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!

**REQUIRES** SWA500 - Dedicated Digital Power Amplifer for CSW Series Subwoofers (required for functionality). Please see related products for more information**

CSW100 Features:

  • Winner: CEA Innovations Design & Engineering Award.*
  • Installs easily between standard floor or ceiling joists, or sits inside an entertainment center.
  • Long-throw 10-inch polycomposite subwoofer driver.
  • Polk’s proprietary, patented Dynamic Balance® technology allows our engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.
  • Klipple optimized coil alignment for extraordinarily efficient shallow-depth motor action even at tremendous volume levels.
  • Rigidly-braced MDF composite enclosure for resonance-free, totally rattle-free performance.
  • Patented high velocity compression drive bandpass alignment with slot-load bass venting for gutsy, driving bass.
  • Heavy duty mounting hardware and professional anti-rattle isolation pads included.
  • Grille opening dimensions: 3-inches H x 12-inches W (7.62cm H x 30.48cm W).
  • Powered for optimum performance by the SWA500 digital amplifier, available separately
