The cabinet has a high-contrast finish with scratch-resistant glossy panels, a textured top, and a magnetic grille to fit beautifully into any decor.

The subwoofer has an advanced 10" ceramic/glass fiber polymer woofer with Deep Channel Design technology to deliver plenty of bass response from little amplifier power. Acoustically tuned bass ports on the cabinet also help to extend low frequency response. BassTrac circuitry is built-in to provide more bass without distortion. The internal amplifier delivers 100W RMS (250W peak) of power for a strong, clear performance.
