8" CompRT 1 Ohm
The 2013 CompRT Thin Subwoofer is the ultimate “mount anywhere” bass solution. Less than four inches deep and capable of tremendously low bass, this weatherproof sub is at home on the trail, in the sand and on the road.

8" CompRT 1 Ohm

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


This shallow-mount subwoofer uses a large-diameter, progressive-roll spider and UV-protected Santoprene surround for truly linear cone movement. A uniquely shaped back plate and bumped top plate allow for full voice-coil movement. All this technology creates outstanding bass in a subwoofer less than three inches deep!


The CompRT Eight-Inch Subwoofer works best with a sealed or ported enclosure and 300 watts of recommended power. See below for more details.
