Kicker 52CVR124 CVR12 CompVR 12" Subwoofer Improved CompVR uses an optimized motor design with dual voice coils, huge magnets and excellent heat management for the pounding bass that you crave. CompVRs feature 2 or 4-ohm dual voice coils, red stitching for tight suspension, and SoloKon for a unified woofer and back brace system. A steel basket reduces vibration as dual high-temp coils drive the molded woofer fast, delivering powerful, distortion-free bass. The woofer cools itself as the cone moves-pushing out hot air when moving down and pulling in cool air when moving up.
