About the CSW100
The Polk Audio CSW100 is a passive in-floor or in-ceiling subwoofer that uses a single 10-inch long-throw Dynamic Balance woofer with a polymer composite cone in a bandpass MDF enclosure, designed to mount between standard floor or ceiling joists with only a small rectangular grille visible after installation. It delivers a total frequency response of 27 Hz to 140 Hz (-3 dB: 33 Hz to 120 Hz) at 8-ohm nominal impedance. The CSW100 must be used with Polk's external SWA500 Class D digital amplifier (sold separately), which is specifically equalized for this model and can power up to two CSW100 units. The enclosure measures 26.25 H x 13 W x 8 D inches, weighs about 33 lbs, and includes gold-plated binding post inputs and a paintable rectangular grille for flush mounting.
