Bass Performance That's Out of Sight

The CSW155 combines stealth convenience with incredible technology to rival the performance of many free-standing, floor-cluttering subwoofers. With one of the shallowest drivers ever engineered (a Polk Audio exclusive), this subwoofer produces air-moving, room-filling bass, while disappearing behind an included perforated aluminum grille (15 1/2" x 17 1/2") that looks like an "air conditioning return" vent. Deep and musical, it's professionally matched to other Polk Audio loudspeakers, allowing you to build the home theater of your dreams in new construction or even in existing walls (60" H x 14" W x 3 3/8" D).
