The CompVX's basket is cast aluminum with motor-cooling perimeter venting and spring-loaded terminals that can accept up to 10-gauge wire, so when you run hundreds of watts to this sub, it gives you loud, distortion-free bass. The CompVX stands alone among round subwoofers, using technologies found in the Solo-Baric L7 like the one-piece SoloKon cone with vented back bracing for ultra-rigidity and a cool motor.
