Product Specifications

The compact speakers of most mini stereo systems have built-in woofers that lack the size and power to faithfully reproduce music's full bass range. With this Powered Subwoofer connected to your mini system, you'll enjoy the deep, rich bass layers you've been missing! This independently powered unit (20 watts RMS, 40 watts peak) fills a room with booming multidirectional bass, yet it has a profile of just 6 1/4 inches to stow discreetly behind couches and chairs. The down-firing bass reflex design provides extended low frequency response while reducing distortion. Links to your mini system via line level (RCA) input or universal (speaker level) input for systems without subwoofer outputs.
