Product Research
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.

I am running 3 of these under the back seat of an 01 Colorado with an FPX 1000.1 and they pound. Nobody believes it until they see it. The sound quality is ridiculous!
