12" CompVX 4 Ohm

The CompVX 12-Inch Subwoofer is a 4Ω dual voice coil design, making it easy to get most out of your amp.


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 12-Inch Subwoofer works best with a sealed or ported enclosure and 750 watts of recommended power. See below for more details.
