About the Polk Audio CSW155
In-wall sub and amp
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.
Note: The enclosure requires a cutout of 14″W x 60″H x 3.375″D. The enclosure is then drywalled over, leaving a 15.5″W x 17.5″H opening for the woofer and slot port, covered by the protective grille.
Plenty of power for great bass
This subwoofer is packaged here with Polk’s separate, cool-running digital amplifier that pumps out 500 watts of solid power. An included custom sound-shaping circuit card precisely tailors the amp’s output for the CSW155. The resulting bass is deep, hard-hitting, and distortion-free. This stable amplifier can also power a pair of the CSW155s for even bigger, stronger bass.
The amp’s standard chassis width lets you stack it neatly with your other audio/video components, or you can hide it away in a cabinet to reduce room clutter.
