Kenwood's KSC-SW1 subwoofer may be just what you need if you're looking for more bass, but don't have space for a conventional sub box or powered sub. This compact sub features an amplifier that pushes 150 watts max to a 6-1/2" woofer, with a 6-1/2" passive radiator built in for good measure. It's all housed in a rugged, low-profile enclosure that will fit just about anywhere.
The passive radiator technology is one of the keys to the surprisingly big sound of the KSC-SW1. Air pressure from the powered woofer moves the unpowered 6-1/2" radiator, augmenting the bass response. Both subs are housed in a non-resonant cabinet with a rigid aluminum die-cast back panel. The rigid cabinet reduces vibrations that distort the output of the speakers, so you'll enjoy clean bass.
Kenwood has included a wiring harness that includes a power and ground cables, speaker input wires, and a fuse. Included mounting brackets help you mount the KSC-SW1 securely. And, the wired remote control lets you adjust the level, phase, and the low-pass filter settings right from the front seat.
