This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" width=\"200\" elevated=\"\" frame=\"\" cooling=\"\"\u003e\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eMany speakers employ venting techniques to enhance voice coil cooling. This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame. The elevated frame technology greatly increases thermal power handling, reduces compression effects and does so without any additional parts.\u003c\/p\u003e\u003c!-- split: SUPPORT :--\u003e\u003cb\u003eDownload  \u003ca title=\"C6-650cw Product Manual\" href=\"https:\/\/jlaudio.widen.net\/s\/7qxdtkgbw5\/c6-650cw_man\"\u003e\u003cspan style=\"color: #707073; padding-right: 24px; background: url(\" https: no-repeat right center\u003eC6-650cw Product Manual\u003c\/span\u003e\u003c\/a\u003e\u003cbr\u003e\u003c\/b\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eUSA Limited Warranty:  \u003cspan style=\"color: #707073; padding-right: 12px;\"\u003eOne (1) year from the original date of purchase\u003c\/span\u003e\u003cspan style=\"font-size: 12px;\"\u003e\u003ca href=\"https:\/\/jlaudio.zendesk.com\/hc\/en-us\/articles\/211960818\" target=\"_blank\"\u003eWarranty Details\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eFind the answers to many common questions:\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/jlaudio.zendesk.com\/hc\/en-us\"\u003e\u003cimg src=\"https:\/\/theme.zdassets.com\/theme_assets\/215492\/d1b7fe828af8a716385d044bb61fc13eb9c1e9a1.png\"\u003e\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003c!-- split: PRESS :--\u003e\u003c!-- split: USER REVIEWS :--\u003e","brand":"JL Audio","offers":[{"title":"Default Title","offer_id":44663638458526,"sku":"99059","price":299.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0672\/5992\/4638\/files\/C6-650cw-FLT_71b14078-d6e8-4e89-8f31-b72761dd56fc.jpg?v=1736206440"},{"product_id":"10w1v3-2-car-audio-w1v3-subwoofers-92080","title":"10W1V3 2 CAR AUDIO W1V3 SUBWOOFERS 92080","description":"\u003c!-- split: OVERVIEW :--\u003e\n\u003cp\u003eW1v3 10-inch Subwoofer (300 W, 2 Ω)\u003c\/p\u003e\n\u003cp\u003eThe 10W1v3 is an outstanding choice when space is very tight and amplifier power is moderate.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\n\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\n\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eMany speakers employ venting techniques to enhance voice coil cooling. This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\n\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\n\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame.

The benefit is a more precisely built, more mechanically sound loudspeaker.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eCarefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\n\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\n\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\n\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\n\u003c!-- split: SUPPORT :--\u003e\n\u003cp\u003e\u003cb\u003e\u003ca href=\"https:\/\/embed.widencdn.net\/pdf\/plus\/jlaudio\/amvyoijyrt\/10W1v3_MAN.pdf?u=ndijqi\" style=\"color: #707073; padding-right: 24px; background: url(;\"\u003e\u003c\/a\u003e\u003c\/b\u003e \u003c\/p\u003e\n\u003cp\u003eUSA Limited Warranty:  \u003cspan style=\"color: #707073; padding-right: 12px;\"\u003eOne (1) year from the original date of purchase.\u003c\/span\u003e\u003cspan style=\"font-size: 12px;\"\u003e\u003c\/span\u003e \u003c\/p\u003e\n\u003cp\u003eFind the answers to many common questions:\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/jlaudio.zendesk.com\/hc\/en-us\"\u003e\u003cimg src=\"https:\/\/theme.zdassets.com\/theme_assets\/215492\/d1b7fe828af8a716385d044bb61fc13eb9c1e9a1.png\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c!-- split: PRESS :--\u003e\u003c!-- split: USER REVIEWS :--\u003e","brand":"JL Audio","offers":[{"title":"Default Title","offer_id":44663662772382,"sku":"92080","price":229.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0672\/5992\/4638\/files\/10W1v3-FLT_d5ae6ee8-f8c7-4d39-88b6-aa7764c70985.jpg?v=1736206280"},{"product_id":"10w3v3-4-car-audio-w3v3-subwoofers-92151","title":"10W3V3 4 CAR AUDIO W3V3 SUBWOOFERS 92151","description":"\u003c!-- split: OVERVIEW :--\u003e\n\u003cp\u003eW3v3 10-inch Subwoofer (500 W, 4 Ω)\u003c\/p\u003e\n\u003cp\u003eThis acclaimed Subwoofer strikes an outstanding balance in power handling, enclosure requirements and excursion to deliver excellent results in medium power applications.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\n\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker.

This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\n\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\n\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame. The elevated frame technology greatly increases thermal power handling, reduces compression effects and does so without any additional parts.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eFloating Cone Attach Method - FCAMâ„\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eJL Audio's patented FCAMâ„¢ technology is an innovative method of bonding the surround\/cone assembly to the voice coil former\/spider assembly.

To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\n\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\n\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\n\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\n\u003ch3\u003eBuilt in U.S.A. with Global Components\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eAt a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\n\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eCarefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\n\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\n\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\n\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eTab-Ear Frame Design\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis frame design feature facilitates mounting the Subwoofer in tight spaces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eBy employing a tab-ear mounting system, the driver's overall outside dimensions are reduced, permitting it to be mounted in a space that is very similar to that required by the next smaller round woofer frame.\u003c\/p\u003e\n\u003cp\u003eIn this example, the “Tab-Ear” frame design allows a 13TW5 13.5-inch driver to fit in a space only slightly larger than a conventional 12-inch woofer requires (only 0.44 in. \/ 11.2 mm bigger)\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/u8nriwmwrg\/TabEar_Design.svg?u=rfhkrg\" alt=\"Comparison of 12.52-inch diameter 12W3v3 to 12.96-inch diameter 13TW5 with Tab-Ear mounting and nearly the same footprint\" width=\"600\"\u003e\u003c\/p\u003e\n\u003ch3\u003eConcentric Tube Suspension\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eOur Concentric Tube Suspensionâ„¢ technology delivers unprecedented excursion in a low-profile woofer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eThe biggest challenge in any low-profile woofer design is to create enough mechanical clearance for the speaker to generate enough excursion to meet its output and low-frequency extension goals.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\n\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/dtw48c0qot\/JLA-ELWS-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eCarefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\n\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\n\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\n\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fyt7d3oxb9\/JLA-TabEar-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eTab-Ear Frame Design\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis frame design feature facilitates mounting the Subwoofer in tight spaces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eBy employing a tab-ear mounting system, the driver's overall outside dimensions are reduced, permitting it to be mounted in a space that is very similar to that required by the next smaller round woofer frame.\u003c\/p\u003e\n\u003cp\u003eIn this example, the “Tab-Ear” frame design allows a 13TW5 13.5-inch driver to fit in a space only slightly larger than a conventional 12-inch woofer requires (only 0.44 in. \/ 11.2 mm bigger)\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/u8nriwmwrg\/TabEar_Design.svg?u=rfhkrg\" alt=\"Comparison of 12.52-inch diameter 12W3v3 to 12.96-inch diameter 13TW5 with Tab-Ear mounting and nearly the same footprint\" width=\"600\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/xunqiuuczj\/JLA-ConcentricTube-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eConcentric Tube Suspension\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eOur Concentric Tube Suspensionâ„¢ technology delivers unprecedented excursion in a low-profile woofer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eThe biggest challenge in any low-profile woofer design is to create enough mechanical clearance for the speaker to generate enough excursion to meet its output and low-frequency extension goals.

Do not use any material with a thickness of less than 0.625 in (16 mm) as this may compromise the rigidity of the enclosure.\u003cbr\u003e* All enclosure volumes listed above are net internal volumes!

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\n\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker.

This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\n\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\n\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame. The elevated frame technology greatly increases thermal power handling, reduces compression effects and does so without any additional parts.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/4ytvbjbzta\/JLA-FCAM-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eFloating Cone Attach Method - FCAMâ„¢\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eJL Audio's patented FCAMâ„¢ technology is an innovative method of bonding the surround\/cone assembly to the voice coil former\/spider assembly.

To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\n\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\n\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\n\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fn0gmjcegm\/JLA-BuiltinUSA-Logo-C.svg?u=fhkrg%20alt=\" in=\"\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eBuilt in U.S.A. with Global Components\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eAt a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow.

We recommend bolting the enclosure through the metal of the floorpan or the frame of the vehicle with large diameter washers for reinforcement.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\n\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\n\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eMany speakers employ venting techniques to enhance voice coil cooling. This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\n\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\n\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame. The elevated frame technology greatly increases thermal power handling, reduces compression effects and does so without any additional parts.\u003c\/p\u003e\n\u003c!-- split: SUPPORT :--\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eUSA Limited Warranty:  \u003cspan style=\"color: #707073; padding-right: 12px;\"\u003eOne (1) year from the original date of purchase.\u003c\/span\u003e \u003c\/p\u003e\n\u003cp\u003eFind the answers to many common questions:\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/jlaudio.zendesk.com\/hc\/en-us\"\u003e\u003cimg src=\"https:\/\/theme.zdassets.com\/theme_assets\/215492\/d1b7fe828af8a716385d044bb61fc13eb9c1e9a1.png\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c!-- split: PRESS :--\u003e\u003c!-- split: USER REVIEWS :--\u003e","brand":"JL Audio","offers":[{"title":"Default Title","offer_id":44663665688734,"sku":"92166","price":149.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0672\/5992\/4638\/files\/12W0v3-FLT.jpg?v=1736206284"},{"product_id":"12w1v3-4-car-audio-w1v3-subwoofers-92083","title":"12W1V3 4 CAR AUDIO W1V3 SUBWOOFERS 92083","description":"\u003c!-- split: OVERVIEW :--\u003e\n\u003cp\u003eW1v3 12-inch Subwoofer (300 W, 4 Ω)\u003c\/p\u003e\n\u003cp\u003eThe 12W1v3 is a lightweight 12-inch driver with excellent performance capabilities at moderate power levels.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\n\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\n\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker.

This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\n\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\n\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame.

To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\n\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\n\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\n\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003c!-- split: SUPPORT :--\u003e\n\u003cp\u003eUSA Limited Warranty:  \u003cspan style=\"color: #707073; padding-right: 12px;\"\u003eOne (1) year from the original date of purchase.\u003c\/span\u003e\u003cspan style=\"font-size: 12px;\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eFind the answers to many common questions:\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/jlaudio.zendesk.com\/hc\/en-us\"\u003e\u003cimg src=\"https:\/\/theme.zdassets.com\/theme_assets\/215492\/d1b7fe828af8a716385d044bb61fc13eb9c1e9a1.png\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c!-- split: PRESS :--\u003e\u003c!-- split: USER REVIEWS :--\u003e","brand":"JL Audio","offers":[{"title":"Default Title","offer_id":44663666868382,"sku":"92083","price":249.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0672\/5992\/4638\/files\/12W1v3-FLT_4c493965-90eb-4f56-94b1-09d20d958712.jpg?v=1736206285"},{"product_id":"12tw1-4-car-audio-tw1-subwoofers-92187","title":"12TW1 4 CAR AUDIO TW1 SUBWOOFERS 92187","description":"\u003c!-- split: OVERVIEW :--\u003e\n\u003cp\u003eTW1 12-inch Subwoofer (300 W, 4 Ω) \u003c\/p\u003e\n\u003cp\u003eBuilt on JL Audio's patented thin-line subwoofer technology, the 12TW1 delivers a powerful combination of shallow mounting depth and excursion capability, while operating in insanely small enclosures (0.65 cu.ft. \/ 18.4 liters).

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\n\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/dtw48c0qot\/JLA-ELWS-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eCarefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\n\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\n\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\n\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\n\u003ch3\u003eTab-Ear Frame Design\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis frame design feature facilitates mounting the Subwoofer in tight spaces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eBy employing a tab-ear mounting system, the driver's overall outside dimensions are reduced, permitting it to be mounted in a space that is very similar to that required by the next smaller round woofer frame.\u003c\/p\u003e\n\u003cp\u003eIn this example, the “Tab-Ear” frame design allows a 13TW5 13.5-inch driver to fit in a space only slightly larger than a conventional 12-inch woofer requires (only 0.44 in. \/ 11.2 mm bigger)\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/u8nriwmwrg\/TabEar_Design.svg?u=rfhkrg\" alt=\"Comparison of 12.52-inch diameter 12W3v3 to 12.96-inch diameter 13TW5 with Tab-Ear mounting and nearly the same footprint\" width=\"600\"\u003e\u003c\/p\u003e\n\u003ch3\u003eConcentric Tube Suspension\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eOur Concentric Tube Suspensionâ„¢ technology delivers unprecedented excursion in a low-profile woofer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eThe biggest challenge in any low-profile woofer design is to create enough mechanical clearance for the speaker to generate enough excursion to meet its output and low-frequency extension goals.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\n\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker.

This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\n\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\n\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame.

To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\n\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\n\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\n\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\n\u003ch3\u003eBuilt in U.S.A. with Global Components\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eAt a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\n\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\n\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eCarefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\n\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\n\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\n\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\n\u003ch3\u003eTab-Ear Frame Design\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis frame design feature facilitates mounting the Subwoofer in tight spaces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eBy employing a tab-ear mounting system, the driver's overall outside dimensions are reduced, permitting it to be mounted in a space that is very similar to that required by the next smaller round woofer frame.\u003c\/p\u003e\n\u003cp\u003eIn this example, the “Tab-Ear” frame design allows a 13TW5 13.5-inch driver to fit in a space only slightly larger than a conventional 12-inch woofer requires (only 0.44 in. \/ 11.2 mm bigger)\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eConcentric Tube Suspension\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eOur Concentric Tube Suspensionâ„¢ technology delivers unprecedented excursion in a low-profile woofer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eThe biggest challenge in any low-profile woofer design is to create enough mechanical clearance for the speaker to generate enough excursion to meet its output and low-frequency extension goals.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\n\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eMany speakers employ venting techniques to enhance voice coil cooling. This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\n\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\n\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame. The elevated frame technology greatly increases thermal power handling, reduces compression effects and does so without any additional parts.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/4ytvbjbzta\/JLA-FCAM-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eFloating Cone Attach Method - FCAMâ„¢\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eJL Audio's patented FCAMâ„¢ technology is an innovative method of bonding the surround\/cone assembly to the voice coil former\/spider assembly.

To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\n\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\n\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\n\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/w5cljmnbja\/JLA-TrimRing-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eCustomizable Trim Ring\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis removable ring can be painted to match the installation theme and directly receives JL Audio grille mesh inserts (sold separately).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eThis ABS trim ring is molded in black, but that doesn't mean it has to stay that way.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\n\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/yxmmtifisw\/JLA-W-Cone-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eW-Cone\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThe W-Cone is a unit-body cone assembly that delivers astonishing cone stiffness with minimal mass. The shape also provides superb torsional rigidity, which is critical to maintaining voice coil alignment at the suspension limits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eThe more excursion and motor force a speaker has, the more important cone rigidity becomes. The acceleration forces are extreme, requiring the cone to withstand rapid changes in speed and direction without deformation. Deformation not only leads to distortion, but can also affect the speaker's mechanical integrity by allowing the voice coil to go out of alignment and rub on the top-plate and the pole-piece of the motor.\u003c\/p\u003e\n\u003cp\u003eThere are several approaches to enhancing cone rigidity. The obvious ones are using a thicker material and\/or a stiffer material. In recent years, several manufacturers have used composite cone materials (Kevlar®, fiberglass, etc.) or metals (aluminum, magnesium, titanium alloys). The use of these exotic materials is typically accompanied by marketing claims that the material chosen has exceptional stiffness-to-mass characteristics. These are true statements, but can be misleading. While these materials have excellent stiffness-to-mass properties (compared to paper or poly), they are not lighter than paper or poly in practice. This means that their use accepts the compromise of added moving mass on the design. This leads to efficiency penalties and suspension complications (it's harder to keep a heavy mass aligned properly).\u003c\/p\u003e\n\u003cp\u003eA simple poly cone diaphragm, while sufficient for lower power designs, would not remain rigid under the demands that the W7 design requires. Our engineering team knew that high levels of cone rigidity would be needed, but they focused on achieving rigidity without a huge weight penalty. This ultimately led to the design we call the W-Cone. The W-Cone assembly achieves its rigidity through architectural means, rather than through inherently stiff materials. The design addresses the stiffness issue by using two lightweight mineral-filled polypropylene skins, bonded together at the perimeter and the center of the assembly. The lower skin's cross-section is shaped like a 'W', hence the name, and provides incredible rigidity when bonded to the dished upper skin. The effect is not unlike the trusses of a bridge or the unit-body construction of a modern automobile. In addition to the overall rigidity benefit, the lower skin's shape distributes the force generated by the coil and motor more evenly than a typical diaphragm. The force is not only applied to the apex but also distributed to the perimeter of the outer diaphragm for more linear behavior. A further benefit of the W-Cone is that the upper skin (the one in contact with the listening environment), is isolated from the high air-pressure gradients of the enclosure, further reducing deformation (and distortion).\u003c\/p\u003e\n\u003cp\u003eAs a point of comparison, the W-Cone assembly of a 12W7 is 32% lighter than a typical aluminum-alloy 12-inch cone. If analyzed in terms of weight per square inch of piston area, the W7 cone-body weighs 1.24g\/sq.in., compared to 1.45g\/sq.in. for an aluminum-alloy cone and 1.66g\/sq.in. for a titanium-alloy cone.\u003c\/p\u003e\n\u003cp\u003eSo why polypropylene? As stated above, our patented W-Cone technology achieves all of the benefits of more exotic materials while better suiting the unique nature of the W7. Since the W7 surround is detachable, the moving system (including the diaphragm) is subject to mechanical stress unseen in conventional designs. Because the user can tug on the cone while manipulating the surround, the cone must be able to handle this without buckling or deforming. Paper, metal or brittle composite cones would not handle this well. Our two-skin unit-body cone design achieves outstanding axial and torsional stiffness to withstand all kinds of abuse, and will remain largely unaffected and unblemished.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker.

This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\n\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\n\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame. The elevated frame technology greatly increases thermal power handling, reduces compression effects and does so without any additional parts.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/4ytvbjbzta\/JLA-FCAM-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eFloating Cone Attach Method - FCAMâ„¢\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eJL Audio's patented FCAMâ„¢ technology is an innovative method of bonding the surround\/cone assembly to the voice coil former\/spider assembly. This feature helps ensure concentricity of the surround, spider and voice coil without torquing the suspension to achieve it. This allows for the inevitable, slight variations in production part dimensions without having them negatively impact the integrity of the suspension and coil-centering at high excursions.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/b1yrufo17s\/JLA-Overroll-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eOverRollâ„¢ Surround\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eBy utilizing space wasted in conventional speakers, this ground-breaking innovation controls the W7's massive excursion without sacrificing precious cone area.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eOne of the first things you notice about a W7 is that something is 'missing'... the mounting flange. Of course, this is actually not the case. The mounting flange is simply hidden beneath the surround and is made accessible for mounting purposes by detaching the outer edge of the surround and moving the roll to the inside (a pretty neat little trick). Apart from the obvious benefits of amazing your friends as you pull the surround off your speaker, there is a serious technical issue that led us in this design direction: Effective Piston Area ('Sd'). This is essentially the speaker's 'cylinder bore', to use an automotive engine analogy, and is calculated by measuring the diameter of the diaphragm including one-half of the surround roll-width. In other words, from the top-center of the surround on one side to top-center of the surround on the other side.\u003c\/p\u003e\n\u003cp\u003eThe displacement capability of a speaker is determined by this piston area times the speaker's excursion capability. Displacement of air is directly linked to output potential. Therefore, the more air a speaker can ultimately displace, the louder it can play. That being said, there is a big difference between piston area and excursion: piston area doesn't need power to make it happen. This means that by making a larger piston, you are directly improving displacement for a given amount of excursion and, therefore, making your speaker more efficient. This is not the only factor that governs efficiency, but it is a major one.\u003c\/p\u003e\n\u003cp\u003eTo make a speaker have more excursion capability not only requires a motor design that can deliver more stroke, but also requires a surround rugged enough to handle the demands of longer excursions and controlled enough to keep everything lined up properly. If the surround's roll-width is not adequately large, its behavior (compliance) is not linear over the useful stroke of the woofer and it is more likely to fatigue and fail. For this reason, speakers with longer excursion capability generally need larger surround rolls (we won't comment on the ones that use large rolls strictly for cosmetic effect).\u003c\/p\u003e\n\u003cp\u003eThe problem with big surrounds is that they begin to encroach on the effective piston area of the driver. For example, a typical 12-inch woofer with a medium-sized roll has an effective piston area of 81.52 square inches. Compare this to a fat-surround 12-inch woofer which has a piston area of 69.07 square inches (15.2 % less effective piston area than the medium-size roll.) To overcome this loss, the fat-surround woofer has to produce more excursion to displace the same air as the woofer with the medium surround (and will require more power to do so).\u003c\/p\u003e\n\u003cp\u003eOverRollâ„¢ technology neatly sidesteps this compromise by allowing us to make full use of the entire footprint of the speaker, placing the surround further to the outside than in a conventional woofer. This means that we can use a large roll for all its benefits without sacrificing cone area (in fact, the 12W7 has 1% more piston area than the medium-surround conventional woofer). By maximizing the effective piston\/total footprint ratio, we can deliver more output for a given excursion and outside frame diameter. This means that the prodigious excursion advantage of the W7 can be put to full use enhancing output, rather than making up for lost piston area.\u003c\/p\u003e\n\u003cp\u003eThe technology also provides a geometry advantage on the outside edge of the surround roll, allowing for more linear operation. A further benefit is that the mounting holes are inherently sealed by the surround, resulting in an improved box seal.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/kfc7jfcn87\/JLA-CDPP-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eRadially Cross-Drilled Pole-Piece\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis innovative venting system greatly enhances thermal dissipation and power handling by directing air flow onto the voice coil former, working in conjunction with the Elevated Frame cooling technology to effectively remove heat from the voice coil.

The top portion of the pole-piece is smaller in outside diameter where the holes vent and helps create a high-volume, high-velocity airflow path between the inner-coil cavity and the ambient air of the enclosure.This helps remove super-heated air that is trapped between the coil former and pole-piece on a conventional design, leading to a dramatic improvement in cooling efficiency, especially at high excursions.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/dtw48c0qot\/JLA-ELWS-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eCarefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\n\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\n\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\n\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fn0gmjcegm\/JLA-BuiltinUSA-Logo-C.svg?u=fhkrg%20alt=\" in=\"\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eBuilt in U.S.A. with Global Components\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eAt a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow.

This, combined with a special cast alloy frame design, makes the 12TW1 capable of operating in extremely tight spaces. These include under-seat installations in trucks, 2-seat sports cars and many other creative applications requiring a compact, low profile subwoofer design.\u003c\/p\u003e\u003cp\u003eJL Audio's patented thin-line woofer technology compresses the architecture of the 12TW1 using a 'concentric tube' structure built into the injection-molded cone body. This structure supports the voice coil and a full annular spider, while permitting the placement of a large motor structure further forward in the speaker than with conventional designs.\u003c\/p\u003e\u003cp\u003eThe 12TW1 also features a clever frame design that minimizes the frontal clearance required for the excursion of the driver. This is accomplished by recessing the suspension attachment surface, so that most of the forward excursion occurs within the frame's dimensions. Thanks to this feature, the 12TW1 requires only 0.87 inches (22 mm) of frontal clearance, even with its grille installed. This allows for more efficient use of space and increased enclosure volume within a given overall depth.\u003c\/p\u003e\u003cp\u003eEven though the 12TW1 is optimized for an enclosure much smaller than any other JL Audio twelve-inch Subwoofer, it never sounds like a big woofer struggling in a tiny box...instead, it delivers all the rich, deep, controlled bass you have come to expect from a JL

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/dtw48c0qot\/JLA-ELWS-logo.svg?u=fhkrg%20alt=\" engineered=\"\" lead-wire=\"\" system=\"\" width=\"200\"\u003e\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fyt7d3oxb9\/JLA-TabEar-logo.svg?u=fhkrg%20alt=\" tab-ear=\"\" frame=\"\" design=\"\" width=\"200\"\u003e\u003ch3\u003eTab-Ear Frame Design\u003cbr\u003e\n\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis frame design feature facilitates mounting the Subwoofer in tight spaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eBy employing a tab-ear mounting system, the driver's overall outside dimensions are reduced, permitting it to be mounted in a space that is very similar to that required by the next smaller round woofer frame.\u003c\/p\u003e\u003cp\u003eIn this example, the “Tab-Ear” frame design allows a 13TW5 13.5-inch driver to fit in a space only slightly larger than a conventional 12-inch woofer requires (only 0.44 in. \/ 11.2 mm bigger)\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/u8nriwmwrg\/TabEar_Design.svg?u=rfhkrg\" alt=\"Comparison of 12.52-inch diameter 12W3v3 to 12.96-inch diameter 13TW5 with Tab-Ear mounting and nearly the same footprint\" width=\"600\"\u003e\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/xunqiuuczj\/JLA-ConcentricTube-logo.svg?u=fhkrg%20alt=\" concentric=\"\" tube=\"\" suspension=\"\" width=\"200\"\u003e\u003ch3\u003eConcentric Tube Suspension\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eOur Concentric Tube Suspensionâ„¢ technology delivers unprecedented excursion in a low-profile woofer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eThe biggest challenge in any low-profile woofer design is to create enough mechanical clearance for the speaker to generate enough excursion to meet its output and low-frequency extension goals.

This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\n\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/dtw48c0qot\/JLA-ELWS-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eCarefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\n\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\n\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\n\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fyt7d3oxb9\/JLA-TabEar-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eTab-Ear Frame Design\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis frame design feature facilitates mounting the Subwoofer in tight spaces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eBy employing a tab-ear mounting system, the driver's overall outside dimensions are reduced, permitting it to be mounted in a space that is very similar to that required by the next smaller round woofer frame.\u003c\/p\u003e\n\u003cp\u003eIn this example, the “Tab-Ear” frame design allows a 13TW5 13.5-inch driver to fit in a space only slightly larger than a conventional 12-inch woofer requires (only 0.44 in. \/ 11.2 mm bigger)\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/u8nriwmwrg\/TabEar_Design.svg?u=rfhkrg\" alt=\"Comparison of 12.52-inch diameter 12W3v3 to 12.96-inch diameter 13TW5 with Tab-Ear mounting and nearly the same footprint\" width=\"600\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/xunqiuuczj\/JLA-ConcentricTube-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eConcentric Tube Suspension\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eOur Concentric Tube Suspensionâ„¢ technology delivers unprecedented excursion in a low-profile woofer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eThe biggest challenge in any low-profile woofer design is to create enough mechanical clearance for the speaker to generate enough excursion to meet its output and low-frequency extension goals.

This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" elevated=\"\" frame=\"\" cooling=\"\" width=\"200\"\u003e\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eMany speakers employ venting techniques to enhance voice coil cooling. This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame. The elevated frame technology greatly increases thermal power handling, reduces compression effects and does so without any additional parts.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/4ytvbjbzta\/JLA-FCAM-logo.svg?u=fhkrg%20alt=\" fcam=\"\" width=\"200\"\u003e\u003ch3\u003eFloating Cone Attach Method - FCAMâ„¢\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e \u003c\/strong\u003eJL Audio's patented FCAMâ„¢ technology is an innovative method of bonding the surround\/cone assembly to the voice coil former\/spider assembly.

To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fn0gmjcegm\/JLA-BuiltinUSA-Logo-C.svg?u=fhkrg%20alt=\" built=\"\" in=\"\" u=\"\" s=\"\" a=\"\" with=\"\" global=\"\" components=\"\" width=\"200\"\u003e\u003ch3\u003eBuilt in U.S.A. with Global Components\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eAt a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow.

These powerful machines are able to cut a wide range of features onto a sheet of MDF, with minimal waste and absolute precision. The KOMO machines cut out the woofer holes, terminal holes, cut dado grooves, create countersinks and most importantly, cut the angles at the edges of the panels that form the enclosure's main shell so that these panels fit together precisely, with no gaps or leaks.\u003c\/p\u003e\u003cp\u003eOnce the panels are cut, assembly technicians line them up in the correct order and glue their outer faces onto a long piece of carpet, creating a 'wrap': a long series of panels, hinged temporarily by the carpet. In the next assembly step, our wood assembly teams fill the V-grooves between the panels and any dado grooves that receive dividers or secondary wraps with wood-glue. Once the glue is applied, the enclosure shells folds together along the V-grooves, capturing dividers in the dado grooves and secondary wraps, and evenly spreading the glue throughout the joints. One line of mechanical fasteners is applied to hold the structure together while the wood glue dries.\u003c\/p\u003e\u003cp\u003eThe V-groove technique greatly improves assembly efficiency, and also results in a far stronger and better sealed enclosure than the typical butt-joint construction found on imported enclosures.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/dtw48c0qot\/JLA-ELWS-logo.svg?u=fhkrg%20alt=\" engineered=\"\" lead-wire=\"\" system=\"\" width=\"200\"\u003e\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fyt7d3oxb9\/JLA-TabEar-logo.svg?u=fhkrg%20alt=\" tab-ear=\"\" frame=\"\" design=\"\" width=\"200\"\u003e\u003ch3\u003eTab-Ear Frame Design\u003cbr\u003e\n\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis frame design feature facilitates mounting the Subwoofer in tight spaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eBy employing a tab-ear mounting system, the driver's overall outside dimensions are reduced, permitting it to be mounted in a space that is very similar to that required by the next smaller round woofer frame.\u003c\/p\u003e\u003cp\u003eIn this example, the “Tab-Ear” frame design allows a 13TW5 13.5-inch driver to fit in a space only slightly larger than a conventional 12-inch woofer requires (only 0.44 in. \/ 11.2 mm bigger)\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/u8nriwmwrg\/TabEar_Design.svg?u=rfhkrg\" alt=\"Comparison of 12.52-inch diameter 12W3v3 to 12.96-inch diameter 13TW5 with Tab-Ear mounting and nearly the same footprint\" width=\"600\"\u003e\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/xunqiuuczj\/JLA-ConcentricTube-logo.svg?u=fhkrg%20alt=\" concentric=\"\" tube=\"\" suspension=\"\" width=\"200\"\u003e\u003ch3\u003eConcentric Tube Suspension\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eOur Concentric Tube Suspensionâ„¢ technology delivers unprecedented excursion in a low-profile woofer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eThe biggest challenge in any low-profile woofer design is to create enough mechanical clearance for the speaker to generate enough excursion to meet its output and low-frequency extension goals.

By elevating the frame above the top-plate of the motor (via  stand-offs integrated into the bottom of the frame) a narrow,  high-velocity air-path is created between the bottom surface of the  frame and the top surface of the top-plate. This air path leads directly  to the voice coil and then turns upward into the spider air cavity. By  utilizing the pumping action of the spider through this focused air  path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\u003cp\u003eAnother important benefit is that the upper surface of the top-plate  (one of the speaker's hottest parts) is directly exposed to cooling air  flow, whereas on a conventional design it is isolated from the air flow  by the lower flange of the frame.

Analyzing this behavior is critical to understanding the  distortion mechanisms of a speaker motor and sheds light on the aspects of  motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003e Linear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows  our transducer engineers to make critical adjustments to motor designs  that result in extremely linear, highly stable dynamic loudspeaker motor  systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/dtw48c0qot\/JLA-ELWS-logo.svg?u=fhkrg%20alt=\" engineered lead-wire system width=\"200\"\u003e\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e Carefully engineered  lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme  excursion demands.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\u003cp\u003eThe biggest problem with this approach is that spider limiting  behavior plays a hugely important role a woofer's performance. Lead-wires that  are attached or woven into the spider material can alter the spider's  'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to  asymmetrical spider behavior and non-uniform stress  distribution around the spider circumference. The wire attachment points  can also cause localized pulling and tearing forces at the  spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider  linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\u003cp\u003eTo overcome these issues, JL Audio's engineered flying  lead-wires work in  conjunction with carefully engineered entry and  exit support  structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fyt7d3oxb9\/JLA-TabEar-logo.svg?u=fhkrg%20alt=\" tab-ear frame design width=\"200\"\u003e\u003ch3\u003eTab-Ear Frame Design\u003cbr\u003e\n\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis frame design feature facilitates mounting the Subwoofer in tight spaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eBy employing a tab-ear mounting system, the driver's overall outside dimensions are reduced, permitting it to be mounted in a space that is very similar to that required by the next smaller round woofer frame.\u003c\/p\u003e\u003cp\u003eIn this example, the “Tab-Ear” frame design allows a 13TW5 13.5-inch driver to fit in a space only slightly larger than a conventional 12-inch woofer requires (only 0.44 in. \/ 11.2 mm bigger)\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/u8nriwmwrg\/TabEar_Design.svg?u=rfhkrg\" alt=\"Comparison of 12.52-inch diameter 12W3v3 to 12.96-inch diameter 13TW5 with Tab-Ear mounting and nearly the same footprint\" width=\"600\"\u003e\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/xunqiuuczj\/JLA-ConcentricTube-logo.svg?u=fhkrg%20alt=\" concentric tube suspension width=\"200\"\u003e\u003ch3\u003eConcentric Tube Suspension\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eOur Concentric Tube Suspensionâ„¢ technology delivers unprecedented excursion in a low-profile woofer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eThe biggest challenge in any low-profile woofer design is to create enough mechanical clearance for the speaker to generate enough excursion to meet its output and low-frequency extension goals.

This increases the battery voltage from its nominal 12V to something higher–the more powerful the amplifier, the greater the required voltage. This power conversion is never perfectly efficient–about 10% of what goes into the amplifier is wasted and ends up dissipating into heat.\u003c\/p\u003e\u003cp\u003eJL Audio's Direct Conversion Class-D Technology (DCDâ„¢) innovates by eliminating the need for this power conversion step entirely. Because we are still bound by the laws of physics, the lack of a step-up power supply means we have to extract as much power as possible from the vehicle's 12V supply. If we were to connect a DCDâ„¢ amplifier to a conventional 4-ohm subwoofer with this limitation in place, we would only achieve about 25 watts, and we all know that powering a subwoofer requires a lot more power than this.\u003c\/p\u003e\u003cp\u003eTo overcome this obstacle, the DCDâ„¢ amplifiers have been designed to drive extremely low impedance speaker loads–as low as 1\/4-ohm (0.25 ohm)! With these very low impedance loads, we can deliver up to 500 watts of clean power, subwoofer power. Those who know Ohm's law and that nothing is free realize that this will require a lot of current to flow, and that's exactly what DCDâ„¢ is engineered to deliver...over 50 Amps peak into a speaker!\u003c\/p\u003e\u003cp\u003eTo deal with these high current amounts, the special, very low-impedance JL Audio Subwoofers used with DCDâ„¢ amplifiers are engineered with unique voice coils and tinsel leads.

These powerful machines are able to cut a wide range of features onto a sheet of MDF, with minimal waste and absolute precision. The KOMO machines cut out the woofer holes, terminal holes, cut dado grooves, create countersinks and most importantly, cut the angles at the edges of the panels that form the enclosure's main shell so that these panels fit together precisely, with no gaps or leaks.\u003c\/p\u003e\u003cp\u003eOnce the panels are cut, assembly technicians line them up in the correct order and glue their outer faces onto a long piece of carpet, creating a 'wrap': a long series of panels, hinged temporarily by the carpet. In the next assembly step, our wood assembly teams fill the V-grooves between the panels and any dado grooves that receive dividers or secondary wraps with wood-glue. Once the glue is applied, the enclosure shells folds together along the V-grooves, capturing dividers in the dado grooves and secondary wraps, and evenly spreading the glue throughout the joints. One line of mechanical fasteners is applied to hold the structure together while the wood glue dries.\u003c\/p\u003e\u003cp\u003eThe V-groove technique greatly improves assembly efficiency, and also results in a far stronger and better sealed enclosure than the typical butt-joint construction found on imported enclosures.

In car audio, the desire for lower tuning frequencies from small enclosure volumes leads to long port lengths that often require compromising the port area. These compromises lead to higher airflow speeds through the port, which can create noise as the air is driven across the edge of the port. The flared port design minimizes these airflow effects by providing a smooth transition for the high-speed air flow, rather than an abrupt termination. The result is less noise and cleaner-sounding bass.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/xtrj6rifmb\/JLA-DMA-logo.svg?u=fhkrg%20alt=\" dma=\"\" optimized=\"\" width=\"200\"\u003e\u003ch3\u003eDynamic Motor Analysis - DMA Optimized Motor\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" elevated=\"\" frame=\"\" cooling=\"\" width=\"200\"\u003e\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker.

This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame. The elevated frame technology greatly increases thermal power handling, reduces compression effects and does so without any additional parts.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/4ytvbjbzta\/JLA-FCAM-logo.svg?u=fhkrg%20alt=\" fcam=\"\" width=\"200\"\u003e\u003ch3\u003eFloating Cone Attach Method - FCAMâ„¢\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e \u003c\/strong\u003eJL Audio's patented FCAMâ„¢ technology is an innovative method of bonding the surround\/cone assembly to the voice coil former\/spider assembly.

To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fn0gmjcegm\/JLA-BuiltinUSA-Logo-C.svg?u=fhkrg%20alt=\" built=\"\" in=\"\" u=\"\" s=\"\" a=\"\" with=\"\" global=\"\" components=\"\" width=\"200\"\u003e\u003ch3\u003eBuilt in U.S.A. with Global Components\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eAt a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow.

These powerful machines are able to cut a wide range of features onto a sheet of MDF, with minimal waste and absolute precision. The KOMO machines cut out the woofer holes, terminal holes, cut dado grooves, create countersinks and most importantly, cut the angles at the edges of the panels that form the enclosure's main shell so that these panels fit together precisely, with no gaps or leaks.\u003c\/p\u003e\u003cp\u003eOnce the panels are cut, assembly technicians line them up in the correct order and glue their outer faces onto a long piece of carpet, creating a 'wrap': a long series of panels, hinged temporarily by the carpet.

Once the glue is applied, the enclosure shells folds together along the V-grooves, capturing dividers in the dado grooves and secondary wraps, and evenly spreading the glue throughout the joints.

These compromises lead to higher airflow speeds through the port, which can create noise as the air is driven across the edge of the port.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" elevated=\"\" frame=\"\" cooling=\"\" width=\"200\"\u003e\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker.

By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame.

To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fn0gmjcegm\/JLA-BuiltinUSA-Logo-C.svg?u=fhkrg%20alt=\" built=\"\" in=\"\" u=\"\" s=\"\" a=\"\" with=\"\" global=\"\" components=\"\" width=\"200\"\u003e\u003ch3\u003eBuilt in U.S.A. with Global Components\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eAt a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow.

These powerful machines are able to cut a wide range of features onto a sheet of MDF, with minimal waste and absolute precision. The KOMO machines cut out the woofer holes, terminal holes, cut dado grooves, create countersinks and most importantly, cut the angles at the edges of the panels that form the enclosure's main shell so that these panels fit together precisely, with no gaps or leaks.\u003c\/p\u003e\u003cp\u003eOnce the panels are cut, assembly technicians line them up in the correct order and glue their outer faces onto a long piece of carpet, creating a 'wrap': a long series of panels, hinged temporarily by the carpet. In the next assembly step, our wood assembly teams fill the V-grooves between the panels and any dado grooves that receive dividers or secondary wraps with wood-glue. Once the glue is applied, the enclosure shells folds together along the V-grooves, capturing dividers in the dado grooves and secondary wraps, and evenly spreading the glue throughout the joints. One line of mechanical fasteners is applied to hold the structure together while the wood glue dries.\u003c\/p\u003e\u003cp\u003eThe V-groove technique greatly improves assembly efficiency, and also results in a far stronger and better sealed enclosure than the typical butt-joint construction found on imported enclosures.

This leads to vastly  reduced distortion and faithfully reproduced transients... or put  simply: tight, clean, articulate bass.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the  forefront of Finite Element Analysis-based modeling of loudspeaker  motors and suspensions. This research is aimed at decoding what we refer to as the  'Loudspeaker Genome'... a project aimed at understanding the true  behavior of loudspeakers under power and in motion. A major component of  this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it  takes a large, complex problem, breaks it down into small solution  elements for analysis and then assembles the data to form an accurate,  'big-picture' solution. DMA's breakthrough is that it actually considers  the effects of power through the coil as well as coil\/cone position  within the framework of a time-domain analysis. This gives us a highly  accurate model of a speaker's actual behavior under real power,  something that the traditional Thiele-Small models or other low power  measurements cannot do. Because DMA does not rely on a steady-state  model, it is able to consider shifts in the circuit elements being  analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon  the magnetic circuit of the motor, specifically the dynamic variations  of the 'fixed' magnetic field. This delivers intensely valuable  information compared to traditional modeling, which assumes that the  'fixed' field produced in the air gap by the magnet and the motor plates  is unchanging. DMA not only shows that this 'fixed' field changes in  reaction to the magnetic field created by current flowing through the  voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the  distortion mechanisms of a speaker motor and sheds light on the aspects of  motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003e Linear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows  our transducer engineers to make critical adjustments to motor designs  that result in extremely linear, highly stable dynamic loudspeaker motor  systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/4ytvbjbzta\/JLA-FCAM-logo.svg?u=fhkrg%20alt=\" fcam width=\"200\"\u003e\u003ch3\u003eFloating Cone Attach Method - FCAMâ„¢\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e This assembly technique, conceived by JL Audio,  ensures proper surround geometry in the assembled speaker for better  excursion control and dynamic voice coil alignment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e \u003c\/strong\u003eJL Audio's patented FCAMâ„¢ technology  is an innovative method of bonding the surround\/cone assembly to the  voice coil former\/spider assembly.

This increases the battery voltage from its nominal 12V to something higher–the more powerful the amplifier, the greater the required voltage. This power conversion is never perfectly efficient–about 10% of what goes into the amplifier is wasted and ends up dissipating into heat.\u003c\/p\u003e\u003cp\u003eJL Audio's Direct Conversion Class-D Technology (DCDâ„¢) innovates by eliminating the need for this power conversion step entirely. Because we are still bound by the laws of physics, the lack of a step-up power supply means we have to extract as much power as possible from the vehicle's 12V supply. If we were to connect a DCDâ„¢ amplifier to a conventional 4-ohm subwoofer with this limitation in place, we would only achieve about 25 watts, and we all know that powering a subwoofer requires a lot more power than this.\u003c\/p\u003e\u003cp\u003eTo overcome this obstacle, the DCDâ„¢ amplifiers have been designed to drive extremely low impedance speaker loads–as low as 1\/4-ohm (0.25 ohm)! With these very low impedance loads, we can deliver up to 500 watts of clean power, subwoofer power. Those who know Ohm's law and that nothing is free realize that this will require a lot of current to flow, and that's exactly what DCDâ„¢ is engineered to deliver...over 50 Amps peak into a speaker!\u003c\/p\u003e\u003cp\u003eTo deal with these high current amounts, the special, very low-impedance JL Audio Subwoofers used with DCDâ„¢ amplifiers are engineered with unique voice coils and tinsel leads.

These powerful machines are able to cut a wide range of features onto a sheet of MDF, with minimal waste and absolute precision. The KOMO machines cut out the woofer holes, terminal holes, cut dado grooves, create countersinks and most importantly, cut the angles at the edges of the panels that form the enclosure's main shell so that these panels fit together precisely, with no gaps or leaks.\u003c\/p\u003e\u003cp\u003eOnce the panels are cut, assembly technicians line them up in the correct order and glue their outer faces onto a long piece of carpet, creating a 'wrap': a long series of panels, hinged temporarily by the carpet. In the next assembly step, our wood assembly teams fill the V-grooves between the panels and any dado grooves that receive dividers or secondary wraps with wood-glue. Once the glue is applied, the enclosure shells folds together along the V-grooves, capturing dividers in the dado grooves and secondary wraps, and evenly spreading the glue throughout the joints. One line of mechanical fasteners is applied to hold the structure together while the wood glue dries.\u003c\/p\u003e\u003cp\u003eThe V-groove technique greatly improves assembly efficiency, and also results in a far stronger and better sealed enclosure than the typical butt-joint construction found on imported enclosures.

These compromises lead to higher airflow speeds through the port, which can create noise as the air is driven across the edge of the port. The flared port design minimizes these airflow effects by providing a smooth transition for the high-speed air flow, rather than an abrupt termination.

This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" elevated=\"\" frame=\"\" cooling=\"\" width=\"200\"\u003e\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker.

This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame.

To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fn0gmjcegm\/JLA-BuiltinUSA-Logo-C.svg?u=fhkrg%20alt=\" built=\"\" in=\"\" u=\"\" s=\"\" a=\"\" with=\"\" global=\"\" components=\"\" width=\"200\"\u003e\u003ch3\u003eBuilt in U.S.A. with Global Components\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eAt a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow.

This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" elevated=\"\" frame=\"\" cooling=\"\" width=\"200\"\u003e\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker.

This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame.

To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/w5cljmnbja\/JLA-TrimRing-logo.svg?u=fhkrg%20alt=\" customizable=\"\" trim=\"\" ring=\"\" width=\"200\"\u003e\u003ch3\u003eCustomizable Trim Ring\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis removable ring can be painted to match the installation theme and directly receives JL Audio grille mesh inserts (sold separately).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eThis ABS trim ring is molded in black, but that doesn't mean it has to stay that way.

With these very low impedance loads, we can deliver up to 500 watts of clean power, subwoofer power. Those who know Ohm's law and that nothing is free realize that this will require a lot of current to flow, and that's exactly what DCDâ„¢ is engineered to deliver...over 50 Amps peak into a speaker!\u003c\/p\u003e\u003cp\u003eTo deal with these high current amounts, the special, very low-impedance JL Audio Subwoofers used with DCDâ„¢ amplifiers are engineered with unique voice coils and tinsel leads. Connections between the amplifier and speaker are made using special heavy gauge speaker cable, with special attention paid to connection integrity to deal with the high current output.\u003c\/p\u003e\u003cp\u003eThe benefit of all this effort is that DCDâ„¢ amplifiers completely avoid the losses associated with a switching power supply, allowing the entire amplifier to achieve total power efficiencies in the 91-94% range. This is very close to the theoretical limit for Class-D efficiency and results in very little heat being generated. All of this allows for a very compact, powerful amplifier that can fit in some of our most space-efficient enclosed systems.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cimg src=\"https:\/\/jlaudio.widen.net\/content\/py0buddffy\/svg\/JLA-V-Groove-logo.svg\" v-groove=\"\" mdf=\"\" construction=\"\" width=\"200\"\u003e\u003ch3\u003eV-Groove MDF Construction\u003cbr\u003e\n\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e This advanced cabinet-building technique uses CNC-machining to create precise panel joints that make enclosure assembly more efficient and exact.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e \u003c\/strong\u003eWe begin with quality medium-density fiberboard, which is then machined on our CNC-controlled KOMO woodworking stations. These powerful machines are able to cut a wide range of features onto a sheet of MDF, with minimal waste and absolute precision. The KOMO machines cut out the woofer holes, terminal holes, cut dado grooves, create countersinks and most importantly, cut the angles at the edges of the panels that form the enclosure's main shell so that these panels fit together precisely, with no gaps or leaks.\u003c\/p\u003e\u003cp\u003eOnce the panels are cut, assembly technicians line them up in the correct order and glue their outer faces onto a long piece of carpet, creating a 'wrap': a long series of panels, hinged temporarily by the carpet. In the next assembly step, our wood assembly teams fill the V-grooves between the panels and any dado grooves that receive dividers or secondary wraps with wood-glue. Once the glue is applied, the enclosure shells folds together along the V-grooves, capturing dividers in the dado grooves and secondary wraps, and evenly spreading the glue throughout the joints. One line of mechanical fasteners is applied to hold the structure together while the wood glue dries.\u003c\/p\u003e\u003cp\u003eThe V-groove technique greatly improves assembly efficiency, and also results in a far stronger and better sealed enclosure than the typical butt-joint construction found on imported enclosures.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/dtw48c0qot\/JLA-ELWS-logo.svg?u=fhkrg%20alt=\" engineered=\"\" lead-wire=\"\" system=\"\" width=\"200\"\u003e\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fyt7d3oxb9\/JLA-TabEar-logo.svg?u=fhkrg%20alt=\" tab-ear=\"\" frame=\"\" design=\"\" width=\"200\"\u003e\u003ch3\u003eTab-Ear Frame Design\u003cbr\u003e\n\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis frame design feature facilitates mounting the Subwoofer in tight spaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eBy employing a tab-ear mounting system, the driver's overall outside dimensions are reduced, permitting it to be mounted in a space that is very similar to that required by the next smaller round woofer frame.\u003c\/p\u003e\u003cp\u003eIn this example, the “Tab-Ear” frame design allows a 13TW5 13.5-inch driver to fit in a space only slightly larger than a conventional 12-inch woofer requires (only 0.44 in. \/ 11.2 mm bigger)\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/u8nriwmwrg\/TabEar_Design.svg?u=rfhkrg\" alt=\"Comparison of 12.52-inch diameter 12W3v3 to 12.96-inch diameter 13TW5 with Tab-Ear mounting and nearly the same footprint\" width=\"600\"\u003e\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/xunqiuuczj\/JLA-ConcentricTube-logo.svg?u=fhkrg%20alt=\" concentric=\"\" tube=\"\" suspension=\"\" width=\"200\"\u003e\u003ch3\u003eConcentric Tube Suspension\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eOur Concentric Tube Suspensionâ„¢ technology delivers unprecedented excursion in a low-profile woofer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eThe biggest challenge in any low-profile woofer design is to create enough mechanical clearance for the speaker to generate enough excursion to meet its output and low-frequency extension goals.

Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\u003cp\u003eTo overcome these issues, JL Audio's engineered flying  lead-wires work in  conjunction with carefully engineered entry and  exit support  structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fyt7d3oxb9\/JLA-TabEar-logo.svg?u=fhkrg%20alt=\" tab-ear frame design width=\"200\"\u003e\u003ch3\u003eTab-Ear Frame Design\u003cbr\u003e\n\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis frame design feature facilitates mounting the Subwoofer in tight spaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eBy employing a tab-ear mounting system, the driver's overall outside dimensions are reduced, permitting it to be mounted in a space that is very similar to that required by the next smaller round woofer frame.\u003c\/p\u003e\u003cp\u003eIn this example, the “Tab-Ear” frame design allows a 13TW5 13.5-inch driver to fit in a space only slightly larger than a conventional 12-inch woofer requires (only 0.44 in. \/ 11.2 mm bigger)\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/u8nriwmwrg\/TabEar_Design.svg?u=rfhkrg\" alt=\"Comparison of 12.52-inch diameter 12W3v3 to 12.96-inch diameter 13TW5 with Tab-Ear mounting and nearly the same footprint\" width=\"600\"\u003e\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/xunqiuuczj\/JLA-ConcentricTube-logo.svg?u=fhkrg%20alt=\" concentric tube suspension width=\"200\"\u003e\u003ch3\u003eConcentric Tube Suspension\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eOur Concentric Tube Suspensionâ„¢ technology delivers unprecedented excursion in a low-profile woofer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eThe biggest challenge in any low-profile woofer design is to create enough mechanical clearance for the speaker to generate enough excursion to meet its output and low-frequency extension goals.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" elevated=\"\" frame=\"\" cooling=\"\" width=\"200\"\u003e\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker.

This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame.

This increases the battery voltage from its nominal 12V to something higher–the more powerful the amplifier, the greater the required voltage. This power conversion is never perfectly efficient–about 10% of what goes into the amplifier is wasted and ends up dissipating into heat.\u003c\/p\u003e\n\u003cp\u003eJL Audio's Direct Conversion Class-D Technology (DCDâ„¢) innovates by eliminating the need for this power conversion step entirely. Because we are still bound by the laws of physics, the lack of a step-up power supply means we have to extract as much power as possible from the vehicle's 12V supply. If we were to connect a DCDâ„¢ amplifier to a conventional 4-ohm subwoofer with this limitation in place, we would only achieve about 25 watts, and we all know that powering a subwoofer requires a lot more power than this.\u003c\/p\u003e\n\u003cp\u003eTo overcome this obstacle, the DCDâ„¢ amplifiers have been designed to drive extremely low impedance speaker loads–as low as 1\/4-ohm (0.25 ohm)! With these very low impedance loads, we can deliver up to 500 watts of clean power, subwoofer power. Those who know Ohm's law and that nothing is free realize that this will require a lot of current to flow, and that's exactly what DCDâ„¢ is engineered to deliver...over 50 Amps peak into a speaker!\u003c\/p\u003e\n\u003cp\u003eTo deal with these high current amounts, the special, very low-impedance JL Audio Subwoofers used with DCDâ„¢ amplifiers are engineered with unique voice coils and tinsel leads.

All of this allows for a very compact, powerful amplifier that can fit in some of our most space-efficient enclosed systems. \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/jlaudio.widen.net\/content\/py0buddffy\/svg\/JLA-V-Groove-logo.svg\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eV-Groove MDF Construction\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis advanced cabinet-building technique uses CNC-machining to create precise panel joints that make enclosure assembly more efficient and exact.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eWe begin with quality medium-density fiberboard, which is then machined on our CNC-controlled KOMO woodworking stations. These powerful machines are able to cut a wide range of features onto a sheet of MDF, with minimal waste and absolute precision. The KOMO machines cut out the woofer holes, terminal holes, cut dado grooves, create countersinks and most importantly, cut the angles at the edges of the panels that form the enclosure's main shell so that these panels fit together precisely, with no gaps or leaks.\u003c\/p\u003e\n\u003cp\u003eOnce the panels are cut, assembly technicians line them up in the correct order and glue their outer faces onto a long piece of carpet, creating a 'wrap': a long series of panels, hinged temporarily by the carpet. In the next assembly step, our wood assembly teams fill the V-grooves between the panels and any dado grooves that receive dividers or secondary wraps with wood-glue. Once the glue is applied, the enclosure shells folds together along the V-grooves, capturing dividers in the dado grooves and secondary wraps, and evenly spreading the glue throughout the joints. One line of mechanical fasteners is applied to hold the structure together while the wood glue dries.\u003c\/p\u003e\n\u003cp\u003eThe V-groove technique greatly improves assembly efficiency, and also results in a far stronger and better sealed enclosure than the typical butt-joint construction found on imported enclosures.

In car audio, the desire for lower tuning frequencies from small enclosure volumes leads to long port lengths that often require compromising the port area. These compromises lead to higher airflow speeds through the port, which can create noise as the air is driven across the edge of the port. The flared port design minimizes these airflow effects by providing a smooth transition for the high-speed air flow, rather than an abrupt termination.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\n\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/dtw48c0qot\/JLA-ELWS-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eCarefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\n\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\n\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\n\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/xunqiuuczj\/JLA-ConcentricTube-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eConcentric Tube Suspension\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eOur Concentric Tube Suspensionâ„¢ technology delivers unprecedented excursion in a low-profile woofer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eThe biggest challenge in any low-profile woofer design is to create enough mechanical clearance for the speaker to generate enough excursion to meet its output and low-frequency extension goals.

This increases the battery voltage from its nominal 12V to something higher–the more powerful the amplifier, the greater the required voltage. This power conversion is never perfectly efficient–about 10% of what goes into the amplifier is wasted and ends up dissipating into heat.\u003c\/p\u003e\n\u003cp\u003eJL Audio's Direct Conversion Class-D Technology (DCDâ„¢) innovates by eliminating the need for this power conversion step entirely. Because we are still bound by the laws of physics, the lack of a step-up power supply means we have to extract as much power as possible from the vehicle's 12V supply. If we were to connect a DCDâ„¢ amplifier to a conventional 4-ohm subwoofer with this limitation in place, we would only achieve about 25 watts, and we all know that powering a subwoofer requires a lot more power than this.\u003c\/p\u003e\n\u003cp\u003eTo overcome this obstacle, the DCDâ„¢ amplifiers have been designed to drive extremely low impedance speaker loads–as low as 1\/4-ohm (0.25 ohm)! With these very low impedance loads, we can deliver up to 500 watts of clean power, subwoofer power. Those who know Ohm's law and that nothing is free realize that this will require a lot of current to flow, and that's exactly what DCDâ„¢ is engineered to deliver...over 50 Amps peak into a speaker!\u003c\/p\u003e\n\u003cp\u003eTo deal with these high current amounts, the special, very low-impedance JL Audio Subwoofers used with DCDâ„¢ amplifiers are engineered with unique voice coils and tinsel leads.

These powerful machines are able to cut a wide range of features onto a sheet of MDF, with minimal waste and absolute precision. The KOMO machines cut out the woofer holes, terminal holes, cut dado grooves, create countersinks and most importantly, cut the angles at the edges of the panels that form the enclosure's main shell so that these panels fit together precisely, with no gaps or leaks.\u003c\/p\u003e\n\u003cp\u003eOnce the panels are cut, assembly technicians line them up in the correct order and glue their outer faces onto a long piece of carpet, creating a 'wrap': a long series of panels, hinged temporarily by the carpet. In the next assembly step, our wood assembly teams fill the V-grooves between the panels and any dado grooves that receive dividers or secondary wraps with wood-glue. Once the glue is applied, the enclosure shells folds together along the V-grooves, capturing dividers in the dado grooves and secondary wraps, and evenly spreading the glue throughout the joints. One line of mechanical fasteners is applied to hold the structure together while the wood glue dries.\u003c\/p\u003e\n\u003cp\u003eThe V-groove technique greatly improves assembly efficiency, and also results in a far stronger and better sealed enclosure than the typical butt-joint construction found on imported enclosures.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\n\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/dtw48c0qot\/JLA-ELWS-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eCarefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\n\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\n\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\n\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fyt7d3oxb9\/JLA-TabEar-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eTab-Ear Frame Design\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis frame design feature facilitates mounting the Subwoofer in tight spaces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eBy employing a tab-ear mounting system, the driver's overall outside dimensions are reduced, permitting it to be mounted in a space that is very similar to that required by the next smaller round woofer frame.\u003c\/p\u003e\n\u003cp\u003eIn this example, the “Tab-Ear” frame design allows a 13TW5 13.5-inch driver to fit in a space only slightly larger than a conventional 12-inch woofer requires (only 0.44 in. \/ 11.2 mm bigger)\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/u8nriwmwrg\/TabEar_Design.svg?u=rfhkrg\" alt=\"Comparison of 12.52-inch diameter 12W3v3 to 12.96-inch diameter 13TW5 with Tab-Ear mounting and nearly the same footprint\" width=\"600\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/xunqiuuczj\/JLA-ConcentricTube-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eConcentric Tube Suspension\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eOur Concentric Tube Suspensionâ„¢ technology delivers unprecedented excursion in a low-profile woofer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eThe biggest challenge in any low-profile woofer design is to create enough mechanical clearance for the speaker to generate enough excursion to meet its output and low-frequency extension goals.

These powerful machines are able to cut a wide range of features onto a sheet of MDF, with minimal waste and absolute precision. The KOMO machines cut out the woofer holes, terminal holes, cut dado grooves, create countersinks and most importantly, cut the angles at the edges of the panels that form the enclosure's main shell so that these panels fit together precisely, with no gaps or leaks.\u003c\/p\u003e\u003cp\u003eOnce the panels are cut, assembly technicians line them up in the correct order and glue their outer faces onto a long piece of carpet, creating a 'wrap': a long series of panels, hinged temporarily by the carpet. In the next assembly step, our wood assembly teams fill the V-grooves between the panels and any dado grooves that receive dividers or secondary wraps with wood-glue. Once the glue is applied, the enclosure shells folds together along the V-grooves, capturing dividers in the dado grooves and secondary wraps, and evenly spreading the glue throughout the joints. One line of mechanical fasteners is applied to hold the structure together while the wood glue dries.\u003c\/p\u003e\u003cp\u003eThe V-groove technique greatly improves assembly efficiency, and also results in a far stronger and better sealed enclosure than the typical butt-joint construction found on imported enclosures.

In car audio, the desire for lower tuning frequencies from small enclosure volumes leads to long port lengths that often require compromising the port area. These compromises lead to higher airflow speeds through the port, which can create noise as the air is driven across the edge of the port. The flared port design minimizes these airflow effects by providing a smooth transition for the high-speed air flow, rather than an abrupt termination. The result is less noise and cleaner-sounding bass.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/xtrj6rifmb\/JLA-DMA-logo.svg?u=fhkrg%20alt=\" dma=\"\" optimized=\"\" width=\"200\"\u003e\u003ch3\u003eDynamic Motor Analysis - DMA Optimized Motor\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/dtw48c0qot\/JLA-ELWS-logo.svg?u=fhkrg%20alt=\" engineered=\"\" lead-wire=\"\" system=\"\" width=\"200\"\u003e\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fyt7d3oxb9\/JLA-TabEar-logo.svg?u=fhkrg%20alt=\" tab-ear=\"\" frame=\"\" design=\"\" width=\"200\"\u003e\u003ch3\u003eTab-Ear Frame Design\u003cbr\u003e\n\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis frame design feature facilitates mounting the Subwoofer in tight spaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eBy employing a tab-ear mounting system, the driver's overall outside dimensions are reduced, permitting it to be mounted in a space that is very similar to that required by the next smaller round woofer frame.\u003c\/p\u003e\u003cp\u003eIn this example, the “Tab-Ear” frame design allows a 13TW5 13.5-inch driver to fit in a space only slightly larger than a conventional 12-inch woofer requires (only 0.44 in. \/ 11.2 mm bigger)\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/u8nriwmwrg\/TabEar_Design.svg?u=rfhkrg\" alt=\"Comparison of 12.52-inch diameter 12W3v3 to 12.96-inch diameter 13TW5 with Tab-Ear mounting and nearly the same footprint\" width=\"600\"\u003e\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/xunqiuuczj\/JLA-ConcentricTube-logo.svg?u=fhkrg%20alt=\" concentric=\"\" tube=\"\" suspension=\"\" width=\"200\"\u003e\u003ch3\u003eConcentric Tube Suspension\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eOur Concentric Tube Suspensionâ„¢ technology delivers unprecedented excursion in a low-profile woofer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eThe biggest challenge in any low-profile woofer design is to create enough mechanical clearance for the speaker to generate enough excursion to meet its output and low-frequency extension goals.

These powerful machines are able to cut a wide range of features onto a sheet of MDF, with minimal waste and absolute precision. The KOMO machines cut out the woofer holes, terminal holes, cut dado grooves, create countersinks and most importantly, cut the angles at the edges of the panels that form the enclosure's main shell so that these panels fit together precisely, with no gaps or leaks.\u003c\/p\u003e\n\u003cp\u003eOnce the panels are cut, assembly technicians line them up in the correct order and glue their outer faces onto a long piece of carpet, creating a 'wrap': a long series of panels, hinged temporarily by the carpet. In the next assembly step, our wood assembly teams fill the V-grooves between the panels and any dado grooves that receive dividers or secondary wraps with wood-glue. Once the glue is applied, the enclosure shells folds together along the V-grooves, capturing dividers in the dado grooves and secondary wraps, and evenly spreading the glue throughout the joints. One line of mechanical fasteners is applied to hold the structure together while the wood glue dries.\u003c\/p\u003e\n\u003cp\u003eThe V-groove technique greatly improves assembly efficiency, and also results in a far stronger and better sealed enclosure than the typical butt-joint construction found on imported enclosures.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\n\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/dtw48c0qot\/JLA-ELWS-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eCarefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\n\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\n\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\n\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fyt7d3oxb9\/JLA-TabEar-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eTab-Ear Frame Design\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis frame design feature facilitates mounting the Subwoofer in tight spaces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eBy employing a tab-ear mounting system, the driver's overall outside dimensions are reduced, permitting it to be mounted in a space that is very similar to that required by the next smaller round woofer frame.\u003c\/p\u003e\n\u003cp\u003eIn this example, the “Tab-Ear” frame design allows a 13TW5 13.5-inch driver to fit in a space only slightly larger than a conventional 12-inch woofer requires (only 0.44 in. \/ 11.2 mm bigger)\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/u8nriwmwrg\/TabEar_Design.svg?u=rfhkrg\" alt=\"Comparison of 12.52-inch diameter 12W3v3 to 12.96-inch diameter 13TW5 with Tab-Ear mounting and nearly the same footprint\" width=\"600\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/xunqiuuczj\/JLA-ConcentricTube-logo.svg?u=fhkrg%20alt=\" width=\"200\"\u003e\u003c\/p\u003e\n\u003ch3\u003eConcentric Tube Suspension\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eOur Concentric Tube Suspensionâ„¢ technology delivers unprecedented excursion in a low-profile woofer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eThe biggest challenge in any low-profile woofer design is to create enough mechanical clearance for the speaker to generate enough excursion to meet its output and low-frequency extension goals.

This increases the battery voltage from its nominal 12V to something higher–the more powerful the amplifier, the greater the required voltage. This power conversion is never perfectly efficient–about 10% of what goes into the amplifier is wasted and ends up dissipating into heat.\u003c\/p\u003e\u003cp\u003eJL Audio's Direct Conversion Class-D Technology (DCDâ„¢) innovates by eliminating the need for this power conversion step entirely. Because we are still bound by the laws of physics, the lack of a step-up power supply means we have to extract as much power as possible from the vehicle's 12V supply. If we were to connect a DCDâ„¢ amplifier to a conventional 4-ohm subwoofer with this limitation in place, we would only achieve about 25 watts, and we all know that powering a subwoofer requires a lot more power than this.\u003c\/p\u003e\u003cp\u003eTo overcome this obstacle, the DCDâ„¢ amplifiers have been designed to drive extremely low impedance speaker loads–as low as 1\/4-ohm (0.25 ohm)! With these very low impedance loads, we can deliver up to 500 watts of clean power, subwoofer power. Those who know Ohm's law and that nothing is free realize that this will require a lot of current to flow, and that's exactly what DCDâ„¢ is engineered to deliver...over 50 Amps peak into a speaker!\u003c\/p\u003e\u003cp\u003eTo deal with these high current amounts, the special, very low-impedance JL Audio Subwoofers used with DCDâ„¢ amplifiers are engineered with unique voice coils and tinsel leads. Connections between the amplifier and speaker are made using special heavy gauge speaker cable, with special attention paid to connection integrity to deal with the high current output.\u003c\/p\u003e\u003cp\u003eThe benefit of all this effort is that DCDâ„¢ amplifiers completely avoid the losses associated with a switching power supply, allowing the entire amplifier to achieve total power efficiencies in the 91-94% range. This is very close to the theoretical limit for Class-D efficiency and results in very little heat being generated. All of this allows for a very compact, powerful amplifier that can fit in some of our most space-efficient enclosed systems.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cimg src=\"https:\/\/jlaudio.widen.net\/content\/py0buddffy\/svg\/JLA-V-Groove-logo.svg\" v-groove=\"\" mdf=\"\" construction=\"\" width=\"200\"\u003e\u003ch3\u003eV-Groove MDF Construction\u003cbr\u003e\n\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e This advanced cabinet-building technique uses CNC-machining to create precise panel joints that make enclosure assembly more efficient and exact.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e \u003c\/strong\u003eWe begin with quality medium-density fiberboard, which is then machined on our CNC-controlled KOMO woodworking stations. These powerful machines are able to cut a wide range of features onto a sheet of MDF, with minimal waste and absolute precision. The KOMO machines cut out the woofer holes, terminal holes, cut dado grooves, create countersinks and most importantly, cut the angles at the edges of the panels that form the enclosure's main shell so that these panels fit together precisely, with no gaps or leaks.\u003c\/p\u003e\u003cp\u003eOnce the panels are cut, assembly technicians line them up in the correct order and glue their outer faces onto a long piece of carpet, creating a 'wrap': a long series of panels, hinged temporarily by the carpet. In the next assembly step, our wood assembly teams fill the V-grooves between the panels and any dado grooves that receive dividers or secondary wraps with wood-glue. Once the glue is applied, the enclosure shells folds together along the V-grooves, capturing dividers in the dado grooves and secondary wraps, and evenly spreading the glue throughout the joints. One line of mechanical fasteners is applied to hold the structure together while the wood glue dries.\u003c\/p\u003e\u003cp\u003eThe V-groove technique greatly improves assembly efficiency, and also results in a far stronger and better sealed enclosure than the typical butt-joint construction found on imported enclosures.

In car audio, the desire for lower tuning frequencies from small enclosure volumes leads to long port lengths that often require compromising the port area. These compromises lead to higher airflow speeds through the port, which can create noise as the air is driven across the edge of the port. The flared port design minimizes these airflow effects by providing a smooth transition for the high-speed air flow, rather than an abrupt termination. The result is less noise and cleaner-sounding bass.\u003c\/p\u003e\u003cp\u003e \u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/xtrj6rifmb\/JLA-DMA-logo.svg?u=fhkrg%20alt=\" dma=\"\" optimized=\"\" width=\"200\"\u003e\u003c\/p\u003e\u003ch3\u003eDynamic Motor Analysis - DMA Optimized Motor\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/dtw48c0qot\/JLA-ELWS-logo.svg?u=fhkrg%20alt=\" engineered=\"\" lead-wire=\"\" system=\"\" width=\"200\"\u003e\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/xunqiuuczj\/JLA-ConcentricTube-logo.svg?u=fhkrg%20alt=\" concentric=\"\" tube=\"\" suspension=\"\" width=\"200\"\u003e\u003ch3\u003eConcentric Tube Suspension\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eOur Concentric Tube Suspensionâ„¢ technology delivers unprecedented excursion in a low-profile woofer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eThe biggest challenge in any low-profile woofer design is to create enough mechanical clearance for the speaker to generate enough excursion to meet its output and low-frequency extension goals.

This leads to vastly  reduced distortion and faithfully reproduced transients... or put  simply: tight, clean, articulate bass.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the  forefront of Finite Element Analysis-based modeling of loudspeaker  motors and suspensions. This research is aimed at decoding what we refer to as the  'Loudspeaker Genome'... a project aimed at understanding the true  behavior of loudspeakers under power and in motion. A major component of  this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it  takes a large, complex problem, breaks it down into small solution  elements for analysis and then assembles the data to form an accurate,  'big-picture' solution. DMA's breakthrough is that it actually considers  the effects of power through the coil as well as coil\/cone position  within the framework of a time-domain analysis. This gives us a highly  accurate model of a speaker's actual behavior under real power,  something that the traditional Thiele-Small models or other low power  measurements cannot do. Because DMA does not rely on a steady-state  model, it is able to consider shifts in the circuit elements being  analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon  the magnetic circuit of the motor, specifically the dynamic variations  of the 'fixed' magnetic field. This delivers intensely valuable  information compared to traditional modeling, which assumes that the  'fixed' field produced in the air gap by the magnet and the motor plates  is unchanging. DMA not only shows that this 'fixed' field changes in  reaction to the magnetic field created by current flowing through the  voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the  distortion mechanisms of a speaker motor and sheds light on the aspects of  motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003e Linear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows  our transducer engineers to make critical adjustments to motor designs  that result in extremely linear, highly stable dynamic loudspeaker motor  systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" elevated frame cooling width=\"200\"\u003e\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the  speaker.

This is typically accomplished  by having big holes in the sides of the frame just below the spider  attachment shelf. While it provides a modest cooling benefit, this  low-velocity air-flow does not blow directly or strongly on the voice  coil.\u003c\/p\u003e\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via  stand-offs integrated into the bottom of the frame) a narrow,  high-velocity air-path is created between the bottom surface of the  frame and the top surface of the top-plate. This air path leads directly  to the voice coil and then turns upward into the spider air cavity. By  utilizing the pumping action of the spider through this focused air  path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\u003cp\u003eAnother important benefit is that the upper surface of the top-plate  (one of the speaker's hottest parts) is directly exposed to cooling air  flow, whereas on a conventional design it is isolated from the air flow  by the lower flange of the frame.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" elevated=\"\" frame=\"\" cooling=\"\" width=\"200\"\u003e\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker.

This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame. The elevated frame technology greatly increases thermal power handling, reduces compression effects and does so without any additional parts.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/4ytvbjbzta\/JLA-FCAM-logo.svg?u=fhkrg%20alt=\" fcam=\"\" width=\"200\"\u003e\u003ch3\u003eFloating Cone Attach Method - FCAMâ„¢\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e \u003c\/strong\u003eJL Audio's patented FCAMâ„¢ technology is an innovative method of bonding the surround\/cone assembly to the voice coil former\/spider assembly.

To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fn0gmjcegm\/JLA-BuiltinUSA-Logo-C.svg?u=fhkrg%20alt=\" built=\"\" in=\"\" u=\"\" s=\"\" a=\"\" with=\"\" global=\"\" components=\"\" width=\"200\"\u003e\u003ch3\u003eBuilt in U.S.A. with Global Components\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eAt a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow.

This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field.

This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\n\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\n\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame. The elevated frame technology greatly increases thermal power handling, reduces compression effects and does so without any additional parts.\u003c\/p\u003e\n\u003cp\u003e\u003cimg width=\"200\" src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/4ytvbjbzta\/JLA-FCAM-logo.svg?u=fhkrg%20alt=\"\u003e\u003c\/p\u003e\n\u003ch3\u003eFloating Cone Attach Method - FCAMâ„¢\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eJL Audio's patented FCAMâ„¢ technology is an innovative method of bonding the surround\/cone assembly to the voice coil former\/spider assembly.

To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\n\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\n\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\n\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\n\u003ch3\u003eCustomizable Trim Ring\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis removable ring can be painted to match the installation theme and directly receives JL Audio grille mesh inserts (sold separately).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eThis ABS trim ring is molded in black, but that doesn't mean it has to stay that way.

This leads to vastly  reduced distortion and faithfully reproduced transients... or put  simply: tight, clean, articulate bass.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the  forefront of Finite Element Analysis-based modeling of loudspeaker  motors and suspensions. This research is aimed at decoding what we refer to as the  'Loudspeaker Genome'... a project aimed at understanding the true  behavior of loudspeakers under power and in motion. A major component of  this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it  takes a large, complex problem, breaks it down into small solution  elements for analysis and then assembles the data to form an accurate,  'big-picture' solution. DMA's breakthrough is that it actually considers  the effects of power through the coil as well as coil\/cone position  within the framework of a time-domain analysis. This gives us a highly  accurate model of a speaker's actual behavior under real power,  something that the traditional Thiele-Small models or other low power  measurements cannot do. Because DMA does not rely on a steady-state  model, it is able to consider shifts in the circuit elements being  analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon  the magnetic circuit of the motor, specifically the dynamic variations  of the 'fixed' magnetic field. This delivers intensely valuable  information compared to traditional modeling, which assumes that the  'fixed' field produced in the air gap by the magnet and the motor plates  is unchanging. DMA not only shows that this 'fixed' field changes in  reaction to the magnetic field created by current flowing through the  voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the  distortion mechanisms of a speaker motor and sheds light on the aspects of  motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003e Linear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows  our transducer engineers to make critical adjustments to motor designs  that result in extremely linear, highly stable dynamic loudspeaker motor  systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" elevated frame cooling width=\"200\"\u003e\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the  speaker. This not only enhances power handling, but also sound quality  by minimizing dynamic parameter shifts and power compression.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eMany speakers employ venting  techniques to enhance voice coil cooling. This is typically accomplished  by having big holes in the sides of the frame just below the spider  attachment shelf. While it provides a modest cooling benefit, this  low-velocity air-flow does not blow directly or strongly on the voice  coil.\u003c\/p\u003e\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via  stand-offs integrated into the bottom of the frame) a narrow,  high-velocity air-path is created between the bottom surface of the  frame and the top surface of the top-plate. This air path leads directly  to the voice coil and then turns upward into the spider air cavity. By  utilizing the pumping action of the spider through this focused air  path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\u003cp\u003eAnother important benefit is that the upper surface of the top-plate  (one of the speaker's hottest parts) is directly exposed to cooling air  flow, whereas on a conventional design it is isolated from the air flow  by the lower flange of the frame. The elevated frame technology greatly  increases thermal power handling, reduces compression effects and does  so without any additional parts.\u003c\/p\u003e\u003c!-- split: SUPPORT :--\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eUSA Limited Warranty:  \u003cspan style=\"color: #707073; padding-right: 12px;\"\u003eTwo (2) years from the original date of purchase\u003c\/span\u003e\u003cspan style=\"font-size: 12px;\"\u003e\u003ca href=\"https:\/\/jlaudio.zendesk.com\/hc\/en-us\/articles\/211960818\" target=\"_blank\"\u003eWarranty Details\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003eFind the answers to many common questions:\u003c\/p\u003e \u003cp\u003e\u003ca href=\"https:\/\/jlaudio.zendesk.com\/hc\/en-us\"\u003e\u003cimg src=\"https:\/\/theme.zdassets.com\/theme_assets\/215492\/d1b7fe828af8a716385d044bb61fc13eb9c1e9a1.png\"\u003e\u003c\/a\u003e\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e\u003c!-- split: PRESS :--\u003e\u003c!-- split: USER REVIEWS :--\u003e","brand":"JL Audio","offers":[{"title":"Default Title","offer_id":44664990367902,"sku":"93281","price":249.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0672\/5992\/4638\/files\/CP112-W0v3-FLT.jpg?v=1736206472"},{"product_id":"13w7ae-d1-5-car-audio-w7ae-subwoofers-92116","title":"13W7AE D1 5 CAR AUDIO W7AE SUBWOOFERS 92116","description":"\u003c!-- split: OVERVIEW :--\u003e\n\u003cp\u003e10th Anniversary Edition - W7 13.5-inch Subwoofer (1500 W, Dual 1.5 Ω voice coils)\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eWords like 'extreme,' 'reference' and 'ultimate' get thrown around quite a bit in the Subwoofer world, but rare is the product that can honestly lay claim to them.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\n\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\n\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\n\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\n\u003cp\u003e\u003cimg width=\"200\" src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/yxmmtifisw\/JLA-W-Cone-logo.svg?u=fhkrg%20alt=\"\u003e\u003c\/p\u003e\n\u003ch3\u003eW-Cone\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThe W-Cone is a unit-body cone assembly that delivers astonishing cone stiffness with minimal mass. The shape also provides superb torsional rigidity, which is critical to maintaining voice coil alignment at the suspension limits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eThe more excursion and motor force a speaker has, the more important cone rigidity becomes. The acceleration forces are extreme, requiring the cone to withstand rapid changes in speed and direction without deformation. Deformation not only leads to distortion, but can also affect the speaker's mechanical integrity by allowing the voice coil to go out of alignment and rub on the top-plate and the pole-piece of the motor.\u003c\/p\u003e\n\u003cp\u003eThere are several approaches to enhancing cone rigidity. The obvious ones are using a thicker material and\/or a stiffer material. In recent years, several manufacturers have used composite cone materials (Kevlar®, fiberglass, etc.) or metals (aluminum, magnesium, titanium alloys). The use of these exotic materials is typically accompanied by marketing claims that the material chosen has exceptional stiffness-to-mass characteristics. These are true statements, but can be misleading. While these materials have excellent stiffness-to-mass properties (compared to paper or poly), they are not lighter than paper or poly in practice. This means that their use accepts the compromise of added moving mass on the design. This leads to efficiency penalties and suspension complications (it's harder to keep a heavy mass aligned properly).\u003c\/p\u003e\n\u003cp\u003eA simple poly cone diaphragm, while sufficient for lower power designs, would not remain rigid under the demands that the W7 design requires. Our engineering team knew that high levels of cone rigidity would be needed, but they focused on achieving rigidity without a huge weight penalty. This ultimately led to the design we call the W-Cone. The W-Cone assembly achieves its rigidity through architectural means, rather than through inherently stiff materials. The design addresses the stiffness issue by using two lightweight mineral-filled polypropylene skins, bonded together at the perimeter and the center of the assembly. The lower skin's cross-section is shaped like a 'W', hence the name, and provides incredible rigidity when bonded to the dished upper skin. The effect is not unlike the trusses of a bridge or the unit-body construction of a modern automobile. In addition to the overall rigidity benefit, the lower skin's shape distributes the force generated by the coil and motor more evenly than a typical diaphragm. The force is not only applied to the apex but also distributed to the perimeter of the outer diaphragm for more linear behavior. A further benefit of the W-Cone is that the upper skin (the one in contact with the listening environment), is isolated from the high air-pressure gradients of the enclosure, further reducing deformation (and distortion).\u003c\/p\u003e\n\u003cp\u003eAs a point of comparison, the W-Cone assembly of a 12W7 is 32% lighter than a typical aluminum-alloy 12-inch cone. If analyzed in terms of weight per square inch of piston area, the W7 cone-body weighs 1.24g\/sq.in., compared to 1.45g\/sq.in. for an aluminum-alloy cone and 1.66g\/sq.in. for a titanium-alloy cone.\u003c\/p\u003e\n\u003cp\u003eSo why polypropylene? As stated above, our patented W-Cone technology achieves all of the benefits of more exotic materials while better suiting the unique nature of the W7. Since the W7 surround is detachable, the moving system (including the diaphragm) is subject to mechanical stress unseen in conventional designs. Because the user can tug on the cone while manipulating the surround, the cone must be able to handle this without buckling or deforming. Paper, metal or brittle composite cones would not handle this well. Our two-skin unit-body cone design achieves outstanding axial and torsional stiffness to withstand all kinds of abuse, and will remain largely unaffected and unblemished.\u003c\/p\u003e\n\u003cp\u003e\u003cimg width=\"200\" src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\"\u003e\u003c\/p\u003e\n\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker.

This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\n\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\n\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame.

Of course, this is actually not the case. The mounting flange is simply hidden beneath the surround and is made accessible for mounting purposes by detaching the outer edge of the surround and moving the roll to the inside (a pretty neat little trick). Apart from the obvious benefits of amazing your friends as you pull the surround off your speaker, there is a serious technical issue that led us in this design direction: Effective Piston Area ('Sd'). This is essentially the speaker's 'cylinder bore', to use an automotive engine analogy, and is calculated by measuring the diameter of the diaphragm including one-half of the surround roll-width. In other words, from the top-center of the surround on one side to top-center of the surround on the other side.\u003c\/p\u003e\n\u003cp\u003eThe displacement capability of a speaker is determined by this piston area times the speaker's excursion capability. Displacement of air is directly linked to output potential. Therefore, the more air a speaker can ultimately displace, the louder it can play. That being said, there is a big difference between piston area and excursion: piston area doesn't need power to make it happen. This means that by making a larger piston, you are directly improving displacement for a given amount of excursion and, therefore, making your speaker more efficient. This is not the only factor that governs efficiency, but it is a major one.\u003c\/p\u003e\n\u003cp\u003eTo make a speaker have more excursion capability not only requires a motor design that can deliver more stroke, but also requires a surround rugged enough to handle the demands of longer excursions and controlled enough to keep everything lined up properly. If the surround's roll-width is not adequately large, its behavior (compliance) is not linear over the useful stroke of the woofer and it is more likely to fatigue and fail. For this reason, speakers with longer excursion capability generally need larger surround rolls (we won't comment on the ones that use large rolls strictly for cosmetic effect).\u003c\/p\u003e\n\u003cp\u003eThe problem with big surrounds is that they begin to encroach on the effective piston area of the driver. For example, a typical 12-inch woofer with a medium-sized roll has an effective piston area of 81.52 square inches. Compare this to a fat-surround 12-inch woofer which has a piston area of 69.07 square inches (15.2 % less effective piston area than the medium-size roll.) To overcome this loss, the fat-surround woofer has to produce more excursion to displace the same air as the woofer with the medium surround (and will require more power to do so).\u003c\/p\u003e\n\u003cp\u003eOverRollâ„¢ technology neatly sidesteps this compromise by allowing us to make full use of the entire footprint of the speaker, placing the surround further to the outside than in a conventional woofer. This means that we can use a large roll for all its benefits without sacrificing cone area (in fact, the 12W7 has 1% more piston area than the medium-surround conventional woofer). By maximizing the effective piston\/total footprint ratio, we can deliver more output for a given excursion and outside frame diameter. This means that the prodigious excursion advantage of the W7 can be put to full use enhancing output, rather than making up for lost piston area.\u003c\/p\u003e\n\u003cp\u003eThe technology also provides a geometry advantage on the outside edge of the surround roll, allowing for more linear operation. A further benefit is that the mounting holes are inherently sealed by the surround, resulting in an improved box seal.\u003c\/p\u003e\n\u003cp\u003e\u003cimg width=\"200\" src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/kfc7jfcn87\/JLA-CDPP-logo.svg?u=fhkrg%20alt=\"\u003e\u003c\/p\u003e\n\u003ch3\u003eRadially Cross-Drilled Pole-Piece\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThis innovative venting system greatly enhances thermal dissipation and power handling by directing air flow onto the voice coil former, working in conjunction with the Elevated Frame cooling technology to effectively remove heat from the voice coil.

Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\n\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\n\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\n\u003cp\u003e\u003cimg width=\"200\" in=\"\" src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fn0gmjcegm\/JLA-BuiltinUSA-Logo-C.svg?u=fhkrg%20alt=\"\u003e\u003c\/p\u003e\n\u003ch3\u003eBuilt in U.S.A. with Global Components\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eAt a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/yxmmtifisw\/JLA-W-Cone-logo.svg?u=fhkrg%20alt=\" width=\"200\" w=\"\" cone=\"\"\u003e\u003ch3\u003eW-Cone\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThe W-Cone is a unit-body cone assembly that delivers astonishing cone stiffness with minimal mass. The shape also provides superb torsional rigidity, which is critical to maintaining voice coil alignment at the suspension limits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eThe more excursion and motor force a speaker has, the more important cone rigidity becomes. The acceleration forces are extreme, requiring the cone to withstand rapid changes in speed and direction without deformation. Deformation not only leads to distortion, but can also affect the speaker's mechanical integrity by allowing the voice coil to go out of alignment and rub on the top-plate and the pole-piece of the motor.\u003c\/p\u003e\u003cp\u003eThere are several approaches to enhancing cone rigidity. The obvious ones are using a thicker material and\/or a stiffer material. In recent years, several manufacturers have used composite cone materials (Kevlar®, fiberglass, etc.) or metals (aluminum, magnesium, titanium alloys). The use of these exotic materials is typically accompanied by marketing claims that the material chosen has exceptional stiffness-to-mass characteristics. These are true statements, but can be misleading. While these materials have excellent stiffness-to-mass properties (compared to paper or poly), they are not lighter than paper or poly in practice. This means that their use accepts the compromise of added moving mass on the design. This leads to efficiency penalties and suspension complications (it's harder to keep a heavy mass aligned properly).\u003c\/p\u003e\u003cp\u003eA simple poly cone diaphragm, while sufficient for lower power designs, would not remain rigid under the demands that the W7 design requires. Our engineering team knew that high levels of cone rigidity would be needed, but they focused on achieving rigidity without a huge weight penalty. This ultimately led to the design we call the W-Cone. The W-Cone assembly achieves its rigidity through architectural means, rather than through inherently stiff materials. The design addresses the stiffness issue by using two lightweight mineral-filled polypropylene skins, bonded together at the perimeter and the center of the assembly. The lower skin's cross-section is shaped like a 'W', hence the name, and provides incredible rigidity when bonded to the dished upper skin. The effect is not unlike the trusses of a bridge or the unit-body construction of a modern automobile. In addition to the overall rigidity benefit, the lower skin's shape distributes the force generated by the coil and motor more evenly than a typical diaphragm. The force is not only applied to the apex but also distributed to the perimeter of the outer diaphragm for more linear behavior. A further benefit of the W-Cone is that the upper skin (the one in contact with the listening environment), is isolated from the high air-pressure gradients of the enclosure, further reducing deformation (and distortion).\u003c\/p\u003e\u003cp\u003eAs a point of comparison, the W-Cone assembly of a 12W7 is 32% lighter than a typical aluminum-alloy 12-inch cone. If analyzed in terms of weight per square inch of piston area, the W7 cone-body weighs 1.24g\/sq.in., compared to 1.45g\/sq.in. for an aluminum-alloy cone and 1.66g\/sq.in. for a titanium-alloy cone.\u003c\/p\u003e\u003cp\u003eSo why polypropylene? As stated above, our patented W-Cone technology achieves all of the benefits of more exotic materials while better suiting the unique nature of the W7. Since the W7 surround is detachable, the moving system (including the diaphragm) is subject to mechanical stress unseen in conventional designs. Because the user can tug on the cone while manipulating the surround, the cone must be able to handle this without buckling or deforming. Paper, metal or brittle composite cones would not handle this well. Our two-skin unit-body cone design achieves outstanding axial and torsional stiffness to withstand all kinds of abuse, and will remain largely unaffected and unblemished.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" width=\"200\" elevated=\"\" frame=\"\" cooling=\"\"\u003e\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker.

This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame. The elevated frame technology greatly increases thermal power handling, reduces compression effects and does so without any additional parts.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/4ytvbjbzta\/JLA-FCAM-logo.svg?u=fhkrg%20alt=\" width=\"200\" fcam=\"\"\u003e\u003ch3\u003eFloating Cone Attach Method - FCAMâ„¢\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e \u003c\/strong\u003eJL Audio's patented FCAMâ„¢ technology is an innovative method of bonding the surround\/cone assembly to the voice coil former\/spider assembly.

Of course, this is actually not the case. The mounting flange is simply hidden beneath the surround and is made accessible for mounting purposes by detaching the outer edge of the surround and moving the roll to the inside (a pretty neat little trick). Apart from the obvious benefits of amazing your friends as you pull the surround off your speaker, there is a serious technical issue that led us in this design direction: Effective Piston Area ('Sd'). This is essentially the speaker's 'cylinder bore', to use an automotive engine analogy, and is calculated by measuring the diameter of the diaphragm including one-half of the surround roll-width. In other words, from the top-center of the surround on one side to top-center of the surround on the other side.\u003c\/p\u003e\u003cp\u003eThe displacement capability of a speaker is determined by this piston area times the speaker's excursion capability. Displacement of air is directly linked to output potential. Therefore, the more air a speaker can ultimately displace, the louder it can play. That being said, there is a big difference between piston area and excursion: piston area doesn't need power to make it happen. This means that by making a larger piston, you are directly improving displacement for a given amount of excursion and, therefore, making your speaker more efficient. This is not the only factor that governs efficiency, but it is a major one.\u003c\/p\u003e\u003cp\u003eTo make a speaker have more excursion capability not only requires a motor design that can deliver more stroke, but also requires a surround rugged enough to handle the demands of longer excursions and controlled enough to keep everything lined up properly. If the surround's roll-width is not adequately large, its behavior (compliance) is not linear over the useful stroke of the woofer and it is more likely to fatigue and fail. For this reason, speakers with longer excursion capability generally need larger surround rolls (we won't comment on the ones that use large rolls strictly for cosmetic effect).\u003c\/p\u003e\u003cp\u003eThe problem with big surrounds is that they begin to encroach on the effective piston area of the driver. For example, a typical 12-inch woofer with a medium-sized roll has an effective piston area of 81.52 square inches. Compare this to a fat-surround 12-inch woofer which has a piston area of 69.07 square inches (15.2 % less effective piston area than the medium-size roll.) To overcome this loss, the fat-surround woofer has to produce more excursion to displace the same air as the woofer with the medium surround (and will require more power to do so).\u003c\/p\u003e\u003cp\u003eOverRollâ„¢ technology neatly sidesteps this compromise by allowing us to make full use of the entire footprint of the speaker, placing the surround further to the outside than in a conventional woofer. This means that we can use a large roll for all its benefits without sacrificing cone area (in fact, the 12W7 has 1% more piston area than the medium-surround conventional woofer). By maximizing the effective piston\/total footprint ratio, we can deliver more output for a given excursion and outside frame diameter. This means that the prodigious excursion advantage of the W7 can be put to full use enhancing output, rather than making up for lost piston area.\u003c\/p\u003e\u003cp\u003eThe technology also provides a geometry advantage on the outside edge of the surround roll, allowing for more linear operation. A further benefit is that the mounting holes are inherently sealed by the surround, resulting in an improved box seal.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/kfc7jfcn87\/JLA-CDPP-logo.svg?u=fhkrg%20alt=\" width=\"200\" cross=\"\" drilled=\"\" pole=\"\"\u003e\u003ch3\u003eRadially Cross-Drilled Pole-Piece\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e This innovative venting system greatly enhances thermal dissipation and power handling by directing air flow onto the voice coil former, working in conjunction with the Elevated Frame cooling technology to effectively remove heat from the voice coil.

To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fn0gmjcegm\/JLA-BuiltinUSA-Logo-C.svg?u=fhkrg%20alt=\" in=\"\" width=\"200\" built=\"\" u=\"\" s=\"\" a=\"\" with=\"\" global=\"\" components=\"\"\u003e\u003ch3\u003eBuilt in U.S.A. with Global Components\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eAt a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow.

This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eLinear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/yxmmtifisw\/JLA-W-Cone-logo.svg?u=fhkrg%20alt=\" w=\"\" cone=\"\" width=\"200\"\u003e\u003ch3\u003eW-Cone\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThe W-Cone is a unit-body cone assembly that delivers astonishing cone stiffness with minimal mass. The shape also provides superb torsional rigidity, which is critical to maintaining voice coil alignment at the suspension limits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eThe more excursion and motor force a speaker has, the more important cone rigidity becomes. The acceleration forces are extreme, requiring the cone to withstand rapid changes in speed and direction without deformation. Deformation not only leads to distortion, but can also affect the speaker's mechanical integrity by allowing the voice coil to go out of alignment and rub on the top-plate and the pole-piece of the motor.\u003c\/p\u003e\u003cp\u003eThere are several approaches to enhancing cone rigidity. The obvious ones are using a thicker material and\/or a stiffer material. In recent years, several manufacturers have used composite cone materials (Kevlar®, fiberglass, etc.) or metals (aluminum, magnesium, titanium alloys). The use of these exotic materials is typically accompanied by marketing claims that the material chosen has exceptional stiffness-to-mass characteristics. These are true statements, but can be misleading. While these materials have excellent stiffness-to-mass properties (compared to paper or poly), they are not lighter than paper or poly in practice. This means that their use accepts the compromise of added moving mass on the design. This leads to efficiency penalties and suspension complications (it's harder to keep a heavy mass aligned properly).\u003c\/p\u003e\u003cp\u003eA simple poly cone diaphragm, while sufficient for lower power designs, would not remain rigid under the demands that the W7 design requires. Our engineering team knew that high levels of cone rigidity would be needed, but they focused on achieving rigidity without a huge weight penalty. This ultimately led to the design we call the W-Cone. The W-Cone assembly achieves its rigidity through architectural means, rather than through inherently stiff materials. The design addresses the stiffness issue by using two lightweight mineral-filled polypropylene skins, bonded together at the perimeter and the center of the assembly. The lower skin's cross-section is shaped like a 'W', hence the name, and provides incredible rigidity when bonded to the dished upper skin. The effect is not unlike the trusses of a bridge or the unit-body construction of a modern automobile. In addition to the overall rigidity benefit, the lower skin's shape distributes the force generated by the coil and motor more evenly than a typical diaphragm. The force is not only applied to the apex but also distributed to the perimeter of the outer diaphragm for more linear behavior. A further benefit of the W-Cone is that the upper skin (the one in contact with the listening environment), is isolated from the high air-pressure gradients of the enclosure, further reducing deformation (and distortion).\u003c\/p\u003e\u003cp\u003eAs a point of comparison, the W-Cone assembly of a 12W7 is 32% lighter than a typical aluminum-alloy 12-inch cone. If analyzed in terms of weight per square inch of piston area, the W7 cone-body weighs 1.24g\/sq.in., compared to 1.45g\/sq.in. for an aluminum-alloy cone and 1.66g\/sq.in. for a titanium-alloy cone.\u003c\/p\u003e\u003cp\u003eSo why polypropylene? As stated above, our patented W-Cone technology achieves all of the benefits of more exotic materials while better suiting the unique nature of the W7. Since the W7 surround is detachable, the moving system (including the diaphragm) is subject to mechanical stress unseen in conventional designs. Because the user can tug on the cone while manipulating the surround, the cone must be able to handle this without buckling or deforming. Paper, metal or brittle composite cones would not handle this well. Our two-skin unit-body cone design achieves outstanding axial and torsional stiffness to withstand all kinds of abuse, and will remain largely unaffected and unblemished.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" elevated=\"\" frame=\"\" cooling=\"\" width=\"200\"\u003e\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker.

This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame.

Of course, this is actually not the case. The mounting flange is simply hidden beneath the surround and is made accessible for mounting purposes by detaching the outer edge of the surround and moving the roll to the inside (a pretty neat little trick). Apart from the obvious benefits of amazing your friends as you pull the surround off your speaker, there is a serious technical issue that led us in this design direction: Effective Piston Area ('Sd'). This is essentially the speaker's 'cylinder bore', to use an automotive engine analogy, and is calculated by measuring the diameter of the diaphragm including one-half of the surround roll-width. In other words, from the top-center of the surround on one side to top-center of the surround on the other side.\u003c\/p\u003e\u003cp\u003eThe displacement capability of a speaker is determined by this piston area times the speaker's excursion capability. Displacement of air is directly linked to output potential. Therefore, the more air a speaker can ultimately displace, the louder it can play. That being said, there is a big difference between piston area and excursion: piston area doesn't need power to make it happen. This means that by making a larger piston, you are directly improving displacement for a given amount of excursion and, therefore, making your speaker more efficient. This is not the only factor that governs efficiency, but it is a major one.\u003c\/p\u003e\u003cp\u003eTo make a speaker have more excursion capability not only requires a motor design that can deliver more stroke, but also requires a surround rugged enough to handle the demands of longer excursions and controlled enough to keep everything lined up properly. If the surround's roll-width is not adequately large, its behavior (compliance) is not linear over the useful stroke of the woofer and it is more likely to fatigue and fail. For this reason, speakers with longer excursion capability generally need larger surround rolls (we won't comment on the ones that use large rolls strictly for cosmetic effect).\u003c\/p\u003e\u003cp\u003eThe problem with big surrounds is that they begin to encroach on the effective piston area of the driver. For example, a typical 12-inch woofer with a medium-sized roll has an effective piston area of 81.52 square inches. Compare this to a fat-surround 12-inch woofer which has a piston area of 69.07 square inches (15.2 % less effective piston area than the medium-size roll.) To overcome this loss, the fat-surround woofer has to produce more excursion to displace the same air as the woofer with the medium surround (and will require more power to do so).\u003c\/p\u003e\u003cp\u003eOverRollâ„¢ technology neatly sidesteps this compromise by allowing us to make full use of the entire footprint of the speaker, placing the surround further to the outside than in a conventional woofer. This means that we can use a large roll for all its benefits without sacrificing cone area (in fact, the 12W7 has 1% more piston area than the medium-surround conventional woofer). By maximizing the effective piston\/total footprint ratio, we can deliver more output for a given excursion and outside frame diameter. This means that the prodigious excursion advantage of the W7 can be put to full use enhancing output, rather than making up for lost piston area.\u003c\/p\u003e\u003cp\u003eThe technology also provides a geometry advantage on the outside edge of the surround roll, allowing for more linear operation. A further benefit is that the mounting holes are inherently sealed by the surround, resulting in an improved box seal.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/kfc7jfcn87\/JLA-CDPP-logo.svg?u=fhkrg%20alt=\" cross=\"\" drilled=\"\" pole=\"\" width=\"200\"\u003e\u003ch3\u003eRadially Cross-Drilled Pole-Piece\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e This innovative venting system greatly enhances thermal dissipation and power handling by directing air flow onto the voice coil former, working in conjunction with the Elevated Frame cooling technology to effectively remove heat from the voice coil.

This helps remove super-heated air that is trapped between the coil former and pole-piece on a conventional design, leading to a dramatic improvement in cooling efficiency, especially at high excursions.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/dtw48c0qot\/JLA-ELWS-logo.svg?u=fhkrg%20alt=\" engineered=\"\" lead-wire=\"\" system=\"\" width=\"200\"\u003e\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fn0gmjcegm\/JLA-BuiltinUSA-Logo-C.svg?u=fhkrg%20alt=\" built=\"\" in=\"\" u=\"\" s=\"\" a=\"\" with=\"\" global=\"\" components=\"\" width=\"200\"\u003e\u003ch3\u003eBuilt in U.S.A. with Global Components\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eAt a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow.

This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field.

DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability.

Deformation not only leads to distortion, but can also affect the speaker's mechanical integrity by allowing the voice coil to go out of alignment and rub on the top-plate and the pole-piece of the motor.\u003c\/p\u003e\u003cp\u003eThere are several approaches to enhancing cone rigidity. The obvious ones are using a thicker material and\/or a stiffer material. In recent years, several manufacturers have used composite cone materials (Kevlar®, fiberglass, etc.) or metals (aluminum, magnesium, titanium alloys). The use of these exotic materials is typically accompanied by marketing claims that the material chosen has exceptional stiffness-to-mass characteristics. These are true statements, but can be misleading. While these materials have excellent stiffness-to-mass properties (compared to paper or poly), they are not lighter than paper or poly in practice. This means that their use accepts the compromise of added moving mass on the design. This leads to efficiency penalties and suspension complications (it's harder to keep a heavy mass aligned properly).\u003c\/p\u003e\u003cp\u003eA simple poly cone diaphragm, while sufficient for lower power designs, would not remain rigid under the demands that the W7 design requires. Our engineering team knew that high levels of cone rigidity would be needed, but they focused on achieving rigidity without a huge weight penalty. This ultimately led to the design we call the W-Cone. The W-Cone assembly achieves its rigidity through architectural means, rather than through inherently stiff materials. The design addresses the stiffness issue by using two lightweight mineral-filled polypropylene skins, bonded together at the perimeter and the center of the assembly. The lower skin's cross-section is shaped like a 'W', hence the name, and provides incredible rigidity when bonded to the dished upper skin. The effect is not unlike the trusses of a bridge or the unit-body construction of a modern automobile. In addition to the overall rigidity benefit, the lower skin's shape distributes the force generated by the coil and motor more evenly than a typical diaphragm. The force is not only applied to the apex but also distributed to the perimeter of the outer diaphragm for more linear behavior. A further benefit of the W-Cone is that the upper skin (the one in contact with the listening environment), is isolated from the high air-pressure gradients of the enclosure, further reducing deformation (and distortion).\u003c\/p\u003e\u003cp\u003eAs a point of comparison, the W-Cone assembly of a 12W7 is 32% lighter than a typical aluminum-alloy 12-inch cone. If analyzed in terms of weight per square inch of piston area, the W7 cone-body weighs 1.24g\/sq.in., compared to 1.45g\/sq.in. for an aluminum-alloy cone and 1.66g\/sq.in. for a titanium-alloy cone.\u003c\/p\u003e\u003cp\u003eSo why polypropylene? As stated above, our patented W-Cone technology achieves all of the benefits of more exotic materials while better suiting the unique nature of the W7. Since the W7 surround is detachable, the moving system (including the diaphragm) is subject to mechanical stress unseen in conventional designs. Because the user can tug on the cone while manipulating the surround, the cone must be able to handle this without buckling or deforming. Paper, metal or brittle composite cones would not handle this well. Our two-skin unit-body cone design achieves outstanding axial and torsional stiffness to withstand all kinds of abuse, and will remain largely unaffected and unblemished.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" elevated=\"\" frame=\"\" cooling=\"\" width=\"200\"\u003e\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker.

This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame. The elevated frame technology greatly increases thermal power handling, reduces compression effects and does so without any additional parts.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/4ytvbjbzta\/JLA-FCAM-logo.svg?u=fhkrg%20alt=\" fcam=\"\" width=\"200\"\u003e\u003ch3\u003eFloating Cone Attach Method - FCAMâ„¢\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e \u003c\/strong\u003eJL Audio's patented FCAMâ„¢ technology is an innovative method of bonding the surround\/cone assembly to the voice coil former\/spider assembly.

Of course, this is actually not the case. The mounting flange is simply hidden beneath the surround and is made accessible for mounting purposes by detaching the outer edge of the surround and moving the roll to the inside (a pretty neat little trick). Apart from the obvious benefits of amazing your friends as you pull the surround off your speaker, there is a serious technical issue that led us in this design direction: Effective Piston Area ('Sd'). This is essentially the speaker's 'cylinder bore', to use an automotive engine analogy, and is calculated by measuring the diameter of the diaphragm including one-half of the surround roll-width. In other words, from the top-center of the surround on one side to top-center of the surround on the other side.\u003c\/p\u003e\u003cp\u003eThe displacement capability of a speaker is determined by this piston area times the speaker's excursion capability. Displacement of air is directly linked to output potential. Therefore, the more air a speaker can ultimately displace, the louder it can play. That being said, there is a big difference between piston area and excursion: piston area doesn't need power to make it happen. This means that by making a larger piston, you are directly improving displacement for a given amount of excursion and, therefore, making your speaker more efficient. This is not the only factor that governs efficiency, but it is a major one.\u003c\/p\u003e\u003cp\u003eTo make a speaker have more excursion capability not only requires a motor design that can deliver more stroke, but also requires a surround rugged enough to handle the demands of longer excursions and controlled enough to keep everything lined up properly. If the surround's roll-width is not adequately large, its behavior (compliance) is not linear over the useful stroke of the woofer and it is more likely to fatigue and fail. For this reason, speakers with longer excursion capability generally need larger surround rolls (we won't comment on the ones that use large rolls strictly for cosmetic effect).\u003c\/p\u003e\u003cp\u003eThe problem with big surrounds is that they begin to encroach on the effective piston area of the driver. For example, a typical 12-inch woofer with a medium-sized roll has an effective piston area of 81.52 square inches. Compare this to a fat-surround 12-inch woofer which has a piston area of 69.07 square inches (15.2 % less effective piston area than the medium-size roll.) To overcome this loss, the fat-surround woofer has to produce more excursion to displace the same air as the woofer with the medium surround (and will require more power to do so).\u003c\/p\u003e\u003cp\u003eOverRollâ„¢ technology neatly sidesteps this compromise by allowing us to make full use of the entire footprint of the speaker, placing the surround further to the outside than in a conventional woofer. This means that we can use a large roll for all its benefits without sacrificing cone area (in fact, the 12W7 has 1% more piston area than the medium-surround conventional woofer). By maximizing the effective piston\/total footprint ratio, we can deliver more output for a given excursion and outside frame diameter. This means that the prodigious excursion advantage of the W7 can be put to full use enhancing output, rather than making up for lost piston area.\u003c\/p\u003e\u003cp\u003eThe technology also provides a geometry advantage on the outside edge of the surround roll, allowing for more linear operation. A further benefit is that the mounting holes are inherently sealed by the surround, resulting in an improved box seal.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/kfc7jfcn87\/JLA-CDPP-logo.svg?u=fhkrg%20alt=\" cross=\"\" drilled=\"\" pole=\"\" width=\"200\"\u003e\u003ch3\u003eRadially Cross-Drilled Pole-Piece\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e This innovative venting system greatly enhances thermal dissipation and power handling by directing air flow onto the voice coil former, working in conjunction with the Elevated Frame cooling technology to effectively remove heat from the voice coil.

The top portion of the pole-piece is smaller in outside diameter where the holes vent and helps create a high-volume, high-velocity airflow path between the inner-coil cavity and the ambient air of the enclosure. This helps remove super-heated air that is trapped between the coil former and pole-piece on a conventional design, leading to a dramatic improvement in cooling efficiency, especially at high excursions.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/dtw48c0qot\/JLA-ELWS-logo.svg?u=fhkrg%20alt=\" engineered=\"\" lead-wire=\"\" system=\"\" width=\"200\"\u003e\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fn0gmjcegm\/JLA-BuiltinUSA-Logo-C.svg?u=fhkrg%20alt=\" built=\"\" in=\"\" u=\"\" s=\"\" a=\"\" with=\"\" global=\"\" components=\"\" width=\"200\"\u003e\u003ch3\u003eBuilt in U.S.A. with Global Components\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eAt a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow.

This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eSince 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the 'Loudspeaker Genome'... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, 'big-picture' solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil\/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the 'fixed' magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the 'fixed' field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this 'fixed' field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability.

The shape also provides superb torsional rigidity, which is critical to maintaining voice coil alignment at the suspension limits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eThe more excursion and motor force a speaker has, the more important cone rigidity becomes. The acceleration forces are extreme, requiring the cone to withstand rapid changes in speed and direction without deformation. Deformation not only leads to distortion, but can also affect the speaker's mechanical integrity by allowing the voice coil to go out of alignment and rub on the top-plate and the pole-piece of the motor.\u003c\/p\u003e\u003cp\u003eThere are several approaches to enhancing cone rigidity. The obvious ones are using a thicker material and\/or a stiffer material. In recent years, several manufacturers have used composite cone materials (Kevlar®, fiberglass, etc.) or metals (aluminum, magnesium, titanium alloys). The use of these exotic materials is typically accompanied by marketing claims that the material chosen has exceptional stiffness-to-mass characteristics. These are true statements, but can be misleading. While these materials have excellent stiffness-to-mass properties (compared to paper or poly), they are not lighter than paper or poly in practice. This means that their use accepts the compromise of added moving mass on the design. This leads to efficiency penalties and suspension complications (it's harder to keep a heavy mass aligned properly).\u003c\/p\u003e\u003cp\u003eA simple poly cone diaphragm, while sufficient for lower power designs, would not remain rigid under the demands that the W7 design requires. Our engineering team knew that high levels of cone rigidity would be needed, but they focused on achieving rigidity without a huge weight penalty. This ultimately led to the design we call the W-Cone. The W-Cone assembly achieves its rigidity through architectural means, rather than through inherently stiff materials. The design addresses the stiffness issue by using two lightweight mineral-filled polypropylene skins, bonded together at the perimeter and the center of the assembly. The lower skin's cross-section is shaped like a 'W', hence the name, and provides incredible rigidity when bonded to the dished upper skin. The effect is not unlike the trusses of a bridge or the unit-body construction of a modern automobile. In addition to the overall rigidity benefit, the lower skin's shape distributes the force generated by the coil and motor more evenly than a typical diaphragm. The force is not only applied to the apex but also distributed to the perimeter of the outer diaphragm for more linear behavior. A further benefit of the W-Cone is that the upper skin (the one in contact with the listening environment), is isolated from the high air-pressure gradients of the enclosure, further reducing deformation (and distortion).\u003c\/p\u003e\u003cp\u003eAs a point of comparison, the W-Cone assembly of a 12W7 is 32% lighter than a typical aluminum-alloy 12-inch cone. If analyzed in terms of weight per square inch of piston area, the W7 cone-body weighs 1.24g\/sq.in., compared to 1.45g\/sq.in. for an aluminum-alloy cone and 1.66g\/sq.in. for a titanium-alloy cone.\u003c\/p\u003e\u003cp\u003eSo why polypropylene? As stated above, our patented W-Cone technology achieves all of the benefits of more exotic materials while better suiting the unique nature of the W7. Since the W7 surround is detachable, the moving system (including the diaphragm) is subject to mechanical stress unseen in conventional designs. Because the user can tug on the cone while manipulating the surround, the cone must be able to handle this without buckling or deforming. Paper, metal or brittle composite cones would not handle this well. Our two-skin unit-body cone design achieves outstanding axial and torsional stiffness to withstand all kinds of abuse, and will remain largely unaffected and unblemished.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" elevated=\"\" frame=\"\" cooling=\"\" width=\"200\"\u003e\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker.

This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.\u003c\/p\u003e\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate. This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\u003cp\u003eAnother important benefit is that the upper surface of the top-plate (one of the speaker's hottest parts) is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame. The elevated frame technology greatly increases thermal power handling, reduces compression effects and does so without any additional parts.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/4ytvbjbzta\/JLA-FCAM-logo.svg?u=fhkrg%20alt=\" fcam=\"\" width=\"200\"\u003e\u003ch3\u003eFloating Cone Attach Method - FCAMâ„¢\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e \u003c\/strong\u003eJL Audio's patented FCAMâ„¢ technology is an innovative method of bonding the surround\/cone assembly to the voice coil former\/spider assembly.

Of course, this is actually not the case. The mounting flange is simply hidden beneath the surround and is made accessible for mounting purposes by detaching the outer edge of the surround and moving the roll to the inside (a pretty neat little trick). Apart from the obvious benefits of amazing your friends as you pull the surround off your speaker, there is a serious technical issue that led us in this design direction: Effective Piston Area ('Sd'). This is essentially the speaker's 'cylinder bore', to use an automotive engine analogy, and is calculated by measuring the diameter of the diaphragm including one-half of the surround roll-width. In other words, from the top-center of the surround on one side to top-center of the surround on the other side.\u003c\/p\u003e\u003cp\u003eThe displacement capability of a speaker is determined by this piston area times the speaker's excursion capability. Displacement of air is directly linked to output potential. Therefore, the more air a speaker can ultimately displace, the louder it can play. That being said, there is a big difference between piston area and excursion: piston area doesn't need power to make it happen. This means that by making a larger piston, you are directly improving displacement for a given amount of excursion and, therefore, making your speaker more efficient. This is not the only factor that governs efficiency, but it is a major one.\u003c\/p\u003e\u003cp\u003eTo make a speaker have more excursion capability not only requires a motor design that can deliver more stroke, but also requires a surround rugged enough to handle the demands of longer excursions and controlled enough to keep everything lined up properly. If the surround's roll-width is not adequately large, its behavior (compliance) is not linear over the useful stroke of the woofer and it is more likely to fatigue and fail. For this reason, speakers with longer excursion capability generally need larger surround rolls (we won't comment on the ones that use large rolls strictly for cosmetic effect).\u003c\/p\u003e\u003cp\u003eThe problem with big surrounds is that they begin to encroach on the effective piston area of the driver. For example, a typical 12-inch woofer with a medium-sized roll has an effective piston area of 81.52 square inches. Compare this to a fat-surround 12-inch woofer which has a piston area of 69.07 square inches (15.2 % less effective piston area than the medium-size roll.) To overcome this loss, the fat-surround woofer has to produce more excursion to displace the same air as the woofer with the medium surround (and will require more power to do so).\u003c\/p\u003e\u003cp\u003eOverRollâ„¢ technology neatly sidesteps this compromise by allowing us to make full use of the entire footprint of the speaker, placing the surround further to the outside than in a conventional woofer. This means that we can use a large roll for all its benefits without sacrificing cone area (in fact, the 12W7 has 1% more piston area than the medium-surround conventional woofer). By maximizing the effective piston\/total footprint ratio, we can deliver more output for a given excursion and outside frame diameter. This means that the prodigious excursion advantage of the W7 can be put to full use enhancing output, rather than making up for lost piston area.\u003c\/p\u003e\u003cp\u003eThe technology also provides a geometry advantage on the outside edge of the surround roll, allowing for more linear operation. A further benefit is that the mounting holes are inherently sealed by the surround, resulting in an improved box seal.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/kfc7jfcn87\/JLA-CDPP-logo.svg?u=fhkrg%20alt=\" cross=\"\" drilled=\"\" pole=\"\" width=\"200\"\u003e\u003ch3\u003eRadially Cross-Drilled Pole-Piece\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e This innovative venting system greatly enhances thermal dissipation and power handling by directing air flow onto the voice coil former, working in conjunction with the Elevated Frame cooling technology to effectively remove heat from the voice coil.

The top portion of the pole-piece is smaller in outside diameter where the holes vent and helps create a high-volume, high-velocity airflow path between the inner-coil cavity and the ambient air of the enclosure.

To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\u003cp\u003eThe biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's 'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\u003cp\u003eTo overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system.

These powerful machines are able to cut a wide range of features onto a sheet of MDF, with minimal waste and absolute precision.

This research is aimed at decoding what we refer to as the  'Loudspeaker Genome'... a project aimed at understanding the true  behavior of loudspeakers under power and in motion. A major component of  this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.\u003c\/p\u003e\u003cp\u003eDMA is a Finite Element Analysis (FEA)-based system, meaning that it  takes a large, complex problem, breaks it down into small solution  elements for analysis and then assembles the data to form an accurate,  'big-picture' solution. DMA's breakthrough is that it actually considers  the effects of power through the coil as well as coil\/cone position  within the framework of a time-domain analysis. This gives us a highly  accurate model of a speaker's actual behavior under real power,  something that the traditional Thiele-Small models or other low power  measurements cannot do. Because DMA does not rely on a steady-state  model, it is able to consider shifts in the circuit elements being  analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.\u003c\/p\u003e\u003cp\u003eDMA is able to analyze the real effects of fluctuating power and excursion upon  the magnetic circuit of the motor, specifically the dynamic variations  of the 'fixed' magnetic field. This delivers intensely valuable  information compared to traditional modeling, which assumes that the  'fixed' field produced in the air gap by the magnet and the motor plates  is unchanging. DMA not only shows that this 'fixed' field changes in  reaction to the magnetic field created by current flowing through the  voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the  distortion mechanisms of a speaker motor and sheds light on the aspects of  motor design that determine truly linear behavior:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003e Linear motor force over the speaker's operational excursion range\u003c\/li\u003e\n\u003cli\u003eConsistent motor force with both positive and negative current through the coil\u003c\/li\u003e\n\u003cli\u003eConsistent motor force at varying applied power levels\u003cbr\u003e \u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eOur ability to fully analyze these aspects of motor behavior allows  our transducer engineers to make critical adjustments to motor designs  that result in extremely linear, highly stable dynamic loudspeaker motor  systems.\u003c\/p\u003e\u003cp\u003eThe payoff is reduced distortion, improved transient performance and stellar sound quality.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/yxmmtifisw\/JLA-W-Cone-logo.svg?u=fhkrg%20alt=\" w cone width=\"200\"\u003e\u003ch3\u003eW-Cone\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eThe W-Cone is a unit-body cone assembly that  delivers astonishing cone stiffness with minimal mass. The shape also  provides superb torsional rigidity, which is critical to maintaining  voice coil alignment at the suspension limits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e\u003c\/strong\u003eThe more excursion and motor force a  speaker has, the more important cone rigidity becomes. The acceleration  forces are extreme, requiring the cone to withstand rapid changes in  speed and direction without deformation. Deformation not only leads to  distortion, but can also affect the speaker's mechanical integrity by  allowing the voice coil to go out of alignment and rub on the top-plate  and the pole-piece of the motor.\u003c\/p\u003e\u003cp\u003eThere are several approaches to enhancing cone rigidity. The obvious  ones are using a thicker material and\/or a stiffer material. In recent  years, several manufacturers have used composite cone materials  (Kevlar®, fiberglass, etc.) or metals (aluminum, magnesium, titanium  alloys). The use of these exotic materials is typically accompanied by  marketing claims that the material chosen has exceptional  stiffness-to-mass characteristics. These are true statements, but can be  misleading. While these materials have excellent stiffness-to-mass  properties (compared to paper or poly), they are not lighter than paper  or poly in practice. This means that their use accepts the compromise of  added moving mass on the design. This leads to efficiency penalties and  suspension complications (it's harder to keep a heavy mass aligned  properly).\u003c\/p\u003e\u003cp\u003eA simple poly cone diaphragm, while sufficient for lower power  designs, would not remain rigid under the demands that the W7 design  requires. Our engineering team knew that high levels of cone rigidity  would be needed, but they focused on achieving rigidity without a huge  weight penalty. This ultimately led to the design we call the W-Cone.  The W-Cone assembly achieves its rigidity through architectural means,  rather than through inherently stiff materials. The design addresses the  stiffness issue by using two lightweight mineral-filled polypropylene  skins, bonded together at the perimeter and the center of the assembly.  The lower skin's cross-section is shaped like a 'W', hence the name, and  provides incredible rigidity when bonded to the dished upper skin. The  effect is not unlike the trusses of a bridge or the unit-body  construction of a modern automobile. In addition to the overall rigidity  benefit, the lower skin's shape distributes the force generated by the  coil and motor more evenly than a typical diaphragm. The force is not  only applied to the apex but also distributed to the perimeter of the  outer diaphragm for more linear behavior. A further benefit of the  W-Cone is that the upper skin (the one in contact with the listening  environment), is isolated from the high air-pressure gradients of the  enclosure, further reducing deformation (and distortion).\u003c\/p\u003e\u003cp\u003eAs a point of comparison, the W-Cone assembly of a 12W7 is 32%  lighter than a typical aluminum-alloy 12-inch cone. If analyzed in terms  of weight per square inch of piston area, the W7 cone-body weighs  1.24g\/sq.in., compared to 1.45g\/sq.in. for an aluminum-alloy cone and  1.66g\/sq.in. for a titanium-alloy cone.\u003c\/p\u003e\u003cp\u003eSo why polypropylene? As stated above, our patented W-Cone technology  achieves all of the benefits of more exotic materials while better  suiting the unique nature of the W7. Since the W7 surround is  detachable, the moving system (including the diaphragm) is subject to  mechanical stress unseen in conventional designs. Because the user can  tug on the cone while manipulating the surround, the cone must be able  to handle this without buckling or deforming. Paper, metal or brittle  composite cones would not handle this well. Our two-skin unit-body cone  design achieves outstanding axial and torsional stiffness to withstand  all kinds of abuse, and will remain largely unaffected and unblemished.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/knnglas3xo\/JLA-ElevatedFrame-logo.svg?u=fhkrg%20alt=\" elevated frame cooling width=\"200\"\u003e\u003ch3\u003eElevated Frame Cooling\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the  speaker.

This is typically accomplished  by having big holes in the sides of the frame just below the spider  attachment shelf. While it provides a modest cooling benefit, this  low-velocity air-flow does not blow directly or strongly on the voice  coil.\u003c\/p\u003e\u003cp\u003eOur design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor (via  stand-offs integrated into the bottom of the frame) a narrow,  high-velocity air-path is created between the bottom surface of the  frame and the top surface of the top-plate. This air path leads directly  to the voice coil and then turns upward into the spider air cavity. By  utilizing the pumping action of the spider through this focused air  path, a large volume of cool air hits the coil windings directly.\u003c\/p\u003e\u003cp\u003eAnother important benefit is that the upper surface of the top-plate  (one of the speaker's hottest parts) is directly exposed to cooling air  flow, whereas on a conventional design it is isolated from the air flow  by the lower flange of the frame. The elevated frame technology greatly  increases thermal power handling, reduces compression effects and does  so without any additional parts.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/4ytvbjbzta\/JLA-FCAM-logo.svg?u=fhkrg%20alt=\" fcam width=\"200\"\u003e\u003ch3\u003eFloating Cone Attach Method - FCAMâ„¢\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e This assembly technique, conceived by JL Audio,  ensures proper surround geometry in the assembled speaker for better  excursion control and dynamic voice coil alignment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003cbr\u003e \u003c\/strong\u003eJL Audio's patented FCAMâ„¢ technology  is an innovative method of bonding the surround\/cone assembly to the  voice coil former\/spider assembly.

Of  course, this is actually not the case. The mounting flange is simply  hidden beneath the surround and is made accessible for mounting  purposes by detaching the outer edge of the surround and moving the  roll to the inside (a pretty neat little trick). Apart from the obvious  benefits of amazing your friends as you pull the surround off your  speaker, there is a serious technical issue that led us in this design  direction: Effective Piston Area ('Sd'). This is essentially the  speaker's 'cylinder bore', to use an automotive engine analogy, and is  calculated by measuring the diameter of the diaphragm including one-half  of the surround roll-width. In other words, from the top-center of the  surround on one side to top-center of the surround on the other side.\u003c\/p\u003e\u003cp\u003eThe displacement capability of a speaker is determined by this piston  area times the speaker's excursion capability. Displacement of air is  directly linked to output potential. Therefore, the more air a speaker  can ultimately displace, the louder it can play. That being said, there  is a big difference between piston area and excursion: piston area  doesn't need power to make it happen. This means that by making a larger  piston, you are directly improving displacement for a given amount of  excursion and, therefore, making your speaker more efficient. This is not  the only factor that governs efficiency, but it is a major one.\u003c\/p\u003e\u003cp\u003eTo make a speaker have more excursion capability not only requires a  motor design that can deliver more stroke, but also requires a surround  rugged enough to handle the demands of longer excursions and controlled  enough to keep everything lined up properly. If the surround's  roll-width is not adequately large, its behavior (compliance) is not  linear over the useful stroke of the woofer and it is more likely to  fatigue and fail. For this reason, speakers with longer excursion  capability generally need larger surround rolls (we won't comment on the  ones that use large rolls strictly for cosmetic effect).\u003c\/p\u003e\u003cp\u003eThe problem with big surrounds is that they begin to encroach on the  effective piston area of the driver. For example, a typical 12-inch woofer with a  medium-sized roll has an effective piston area of 81.52  square inches. Compare this to a fat-surround 12-inch woofer which has a  piston area of 69.07 square inches (15.2 % less effective piston area  than the medium-size roll.) To overcome this loss, the fat-surround woofer has to  produce more excursion to displace the same air as the woofer with the medium surround (and will  require more power to do so).\u003c\/p\u003e\u003cp\u003eOverRollâ„¢ technology neatly sidesteps this compromise by allowing us  to make full use of the entire footprint of the speaker, placing the  surround further to the outside than in a conventional woofer. This  means that we can use a large roll for all its benefits without  sacrificing cone area (in fact, the 12W7 has 1% more piston area than the medium-surround conventional woofer). By maximizing the effective piston\/total footprint ratio, we  can deliver more output for a given excursion and outside frame  diameter. This means that the prodigious excursion advantage of the W7  can be put to full use enhancing output, rather than making up for lost  piston area.\u003c\/p\u003e\u003cp\u003eThe technology also provides a geometry advantage on the outside edge  of the surround roll, allowing for more linear operation. A further  benefit is that the mounting holes are inherently sealed by the  surround, resulting in an improved box seal.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/kfc7jfcn87\/JLA-CDPP-logo.svg?u=fhkrg%20alt=\" cross drilled pole width=\"200\"\u003e\u003ch3\u003eRadially Cross-Drilled Pole-Piece\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e This innovative venting system greatly enhances  thermal dissipation and power handling by directing air flow onto the  voice coil former, working in conjunction with the Elevated Frame  cooling technology to effectively remove heat from the voice coil.

The top portion of the pole-piece is smaller in outside diameter  where the holes vent and helps create a high-volume, high-velocity  airflow path between the inner-coil cavity and the ambient air of the  enclosure.This helps remove super-heated air that is trapped between the  coil former and pole-piece on a conventional design, leading to a  dramatic improvement in cooling efficiency, especially at high  excursions.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/dtw48c0qot\/JLA-ELWS-logo.svg?u=fhkrg%20alt=\" engineered lead-wire system width=\"200\"\u003e\u003ch3\u003eEngineered Lead-Wire System (U.S. Patent #7,356,157) \u003cbr\u003e\n\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003e Carefully engineered  lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme  excursion demands.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eManaging the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.\u003c\/p\u003e\u003cp\u003eThe biggest problem with this approach is that spider limiting  behavior plays a hugely important role a woofer's performance. Lead-wires that  are attached or woven into the spider material can alter the spider's  'stretching' behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to  asymmetrical spider behavior and non-uniform stress  distribution around the spider circumference. The wire attachment points  can also cause localized pulling and tearing forces at the  spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.\u003c\/p\u003e\u003cp\u003eWhile a traditional 'flying lead' design does not compromise spider  linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.\u003c\/p\u003e\u003cp\u003eTo overcome these issues, JL Audio's engineered flying  lead-wires work in  conjunction with carefully engineered entry and  exit support  structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.\u003c\/p\u003e\u003cimg src=\"https:\/\/embed.widencdn.net\/svg\/jlaudio\/fn0gmjcegm\/JLA-BuiltinUSA-Logo-C.svg?u=fhkrg%20alt=\" built in u.s.a. with global components width=\"200\"\u003e\u003ch3\u003eBuilt in U.S.A. with Global Components\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSummary:\u003c\/strong\u003e\u003cbr\u003eJL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Information:\u003c\/strong\u003e\u003cbr\u003eAt a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow.
