Kenwood SW201X Power Bass Reactor Powered Subwoofer

A pre-owned Kenwood SW201X "Power Bass Reactor" powered subwoofer, a cylindrical amplified bass unit made for the Japanese domestic car audio market and now hard to find. The unit combines an 8 in (200 mm) long-stroke woofer with an 8 in (200 mm) passive radiator and a built-in amplifier in a single sealed enclosure, so it can be added to almost any vehicle without a separate amp. It ships with the subwoofer unit, a wiring set, and the wired remote controller. This is an audio amplification device only and has no radio transmitting or receiving function.
