Product Information

CompRTTM Subwoofers have reduced what were already the thinnest mounting depths available from the world's bass leader, taking almost another inch off the shallow-mount driver's basket suitable for the trickiest installations. It's true, deep bass that's made to fit where conventional-sized subwoofers don't.

Despite the shallower mount, CompRT Subwoofers are now available in 1- or 2-Ohm dual-voice coils, made to match perfectly with KICKER KX-Series Mono Amplifiers in a car or truck, or with smaller-scale, low-impedance KICKER PX-Series Amplifiers in a powersports setting. Picking up where the preceding CompVT Series left off, CompRT Subwoofers are engineered to deliver serious bottom-end where space is limited. Whether behind the seat in a compact car or in a motorcycle's saddlebags, make no mistake signature KICKER bass is on board.

The CompRT motor structure is as intricate as one might expect from a shallow-mount subwoofer. It utilizes a large-diameter, progressive-roll spider for increased linearity and better overall sound. An inverted-bumped back plate and a bumped top plate allow for full voice-coil clearance and excursion, creating outstanding bass despite the limited area. High-temp coil wire winding around the high-mass, solid pole piece and double venting contribute to the woofers' efficient cooling attributes and durability. As a result, CompRT power handling has increased dramatically with the newest design.

CompRT features an injection-molded polypropylene cone and tough SantopreneTM surround that interlocks with the front gasket for ultra-rigidity and minimal distortion. The full-coverage, sealed steel basket provides full protection of the motor assembly, and with the interlocking surround and gasket, helps the weather-proof subwoofer perform perfectly in outdoor powersports settings.

CompRT features dual pairs of sturdy, spring-loaded wire terminals that are custom-designed specifically for the basket so the subwoofer can retain its shallow mounting capability.
