Polk Audio CSW155 In-Wall (3.387" deep) Passive Subwoofer

Experience deep, high-impact bass without sacrificing an inch of floor space. Polk's CSW155 installs discreetly in your wall for a clutter-free look. Its 10" driver delivers impressively full, powerful lows - from the earth-shaking rumble of an on-screen avalanche, to the fine, precise tones of an upright bass in a jazz concert. This capable sub features a high-quality build and sophisticated design to ensure clean, smooth low-frequency response. And once it's installed, all you'll see is the included aluminum grille. Polk's separate SWA500 amplifier is an ideal choice for powering the CSW155. Got wire? Most speakers don't include any. Learn more about in-wall wiring at the Crutchfield Learning Center.
