Infinity 4-way black 800W Cascade Series Powered Subwoofer

Bass that 'fits' your room; rumbles and goes 'boom'. Housing its four 6", 800W-powered drivers in a slim 8.5"-deep cabinet enclosure, the Cascade Model Fifteen is the ideal low-frequency complement to your surround-sound system and spacious flat-panel home theater. The Room Adaptive Bass Optimization System matches your Cascade Model Fifteen's performance to the natural acoustics of your living room. A vented-enclosure cabinet design allows for extended low-frequency performance from a more modestly-sized cabinet.
