The CompR 10-Inch Subwoofer is a 4Ω dual voice coil design, making it easy to get the most out of your amp. An advanced suspension and heat management system helps to keep the bass powerful, deep and consistent – all without a hint of distortion. To make our subs even more reliable, KICKER engineers developed Forced Air Cooling to help our subs run 25% cooler than before. The CompR 10-Inch Subwoofer works best with a sealed or ported enclosure and 400 watts of recommended power. See below for more details.
