Features
Cone: The woofer cone is a sandwich design, with a flax center between two glass layers. This combination of materials results in a neutral sound without coloration.
Surround: The rubber surround is resistant to ultraviolet rays, temperature extremes, and humidity to add to the speaker's reliability and longevity.
Spring-Posts: The spring-post speaker terminals offer easy connection of single banana plugs or bare wire up to 10 gauge.
Rubber Gasket: The gasket/mounting-ring ensures better chassis damping and prevents air leakage. The rubber gasket is removable.
Enclosure: Focal recommends a sealed enclosure volume of 0.28 ft³ (examples are given from 0.21 ft³ to 0.32 ft³). Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable for all types of music.
