The Sonance RK10w is a realistic-looking rock subwoofer compliment to the Sonance RK63, RK83 and other outdoor speakers. The RK10w features a built-in crossover that accepts a 4-conductor wire from a zone amplifier and provides high pass filtered speaker level outputs for the main speakers.

Powerful bass frequencies are reproduced by a ported, weatherproof 10-inch (254mm) polypropylene cone woofer while the main speakers playback upper bass through high frequencies. Adding the RK10w subwoofer improves bass impact and authority while allowing the main speakers to handle more power and have better clarity and lower distortion.
