C1 650Se Car Audio Speakers C1 Speaker Systems 99061

2-Way Component System: 6.5-inch (165 mm) Woofer, 1-inch (25 mm) Silk Dome Tweeter

The C1-650se component system is engineered to deliver remarkable fidelity and outstanding value in a format that easily fits in factory locations.

Outfitted with pure, silk dome tweeters, the C1-650se component system stands above others in its category with silky smooth, high-frequency clarity and definition. The 1-inch tweeter’s edge-driven design delivers excellent off-axis response and treble extension. It also benefits from the damping of a silk surround suspension and Ferrofluid in the voice coil gap, along with the superior strength of a neodymium magnet circuit. Outboard, 3rd order, high-pass in-line filters, with Advanced Tweeter Protection Circuitry, are also included to guard against high-distortion damage and improve power handling. For maximum installation versatility, surface and flush tweeter mounts are also included. 

C1 woofer drivers benefit from proprietary FEA modeling and JL Audio's expertise in low-frequency driver design. This knowledge is used to create speakers that can play loudly while maintaining a smooth, dynamic, low-distortion sound. At the core of the C1-650 woofer is a proprietary, stamped, steel 6.5-inch (165 mm) frame and DMA-optimized motor system. A mineral-filled, injection-molded, polypropylene cone is suspended with a rubber surround on the front, and a carefully engineered flat Conex® spider at the top of the voice coil, to precisely control the voice coil's motion. Tinsel leads are carefully routed and attached to each spider to prevent fatigue and buzzing. These are the same kinds of features and materials normally found on much more expensive loudspeakers.

To maximize fit, multi-application adaptor rings are included for the woofers, allowing easy, drop-in installation in vehicles equipped with oversized 6.5-inch and 6.75-inch speaker openings. Without the ring, the woofers will also fit into many '6-inch' speaker locations as well. 

When it comes to value, C1-650se is a real deal!

Dynamic Motor Analysis - DMA Optimized Motor

Summary:
JL 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.

Detailed Information:
Since 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.

DMA 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.

DMA 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:

1. Linear motor force over the speaker's operational excursion range
2. Consistent motor force with both positive and negative current through the coil
3. Consistent motor force at varying applied power levels
    

Our 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.

The payoff is reduced distortion, improved transient performance and stellar sound quality.

 

Silk Dome Tweeter

Summary:
Light, fast moving silk dome material promotes high-frequency accuracy. 

Detailed Information:
Silk is a natural material with inherently good characteristics as a tweeter diaphragm. In addition to being very light in weight, silk exhibits excellent damping properties, which reduces ringing and resonances in the tweeter’s passband, leading to a smooth, pleasing high-frequency character free from unnatural sibilance or exaggerated brightness. Compared to a harder material dome, a silk tweeter does not exhibit as much ultra-high frequency extension, but is preferred by many audiophiles for its overall balance.
