Polk Audio CSW100 Built-in Floor or Ceiling 10" Subwoofer, 27-140 Hz, Single

Bass Performance That's Out of Sight
The Polk CSW100 is the least visually intrusive built-in subwoofer on the market today. It's designed for in-floor, in-ceiling or in-furniture placement. It fits comfortably between standard joists and the narrower QuietFloor spacing. Once installed, all you see is a tiny 4 1/2x14-inch grille (supplied). Visitors to your home will think they're seeing an air vent and they'll wonder where all that awesome bass is coming from!
