The CompRT 12-Inch Subwoofer is an all-weather thin subwoofer with a pair of 1Ω voice coils.


With our custom SoloKon™ technology and the CompRT’s unique interior support system, the sub pounds out deep bass – even in a small enclosure. Match any RT sub with a PX amplifier for an outstanding combination of power and size. 


The CompRT 12-Inch Subwoofer works best with a sealed or ported enclosure and 500 watts of recommended power. See below for more details.
