Details from Polk Audio

    The CSW155 is for everyone who covets uncompromising bass performance in a nearly invisible package. The CSW155 s single 10-inch diameter driver is the shallowest ever engineered by Polk, ensuring the CSW155 fits easily in a wall. This is really big bass that s created with free-standing subwoofer performance and ultra-reliability in mind. The CSW155 stands 60 inches tall but fits comfortably between standard 16-inch on-center studs.

    CSW155 Features:
  • Fits comfortably between standard 16-inch OC (on-center) studs.
  • Single 10-inch diameter driver is the shallowest driver Polk has ever engineered.
  • Klippel Optimized woofer - By using a state-of-the-art Klippel Distortion Analyzer, Polk engineers were able to optimize the woofer s motor structure, voice coil alignment and suspension for the best possible performance and low distortion even at extreme listening levels.
  • Neodymium Motor Structure- made the sub s shallow depth possible without giving up an ounce of performance.
  • Cast Aluminum Basket is rigid and inert to suppress resonance.
  • Massive 2-inch Voice Coil for high bass output and high power handling
  • Inverted Roll Surround-highly reliable design maintains its "springiness over time.
  • Dual spiders ensure linear excursion and prevent the driver from bottoming out.
  • Rigid MDF Slot Ported Enclosure--The port cross section runs the width of the grille. Steel plate on the back of the cabinet stiffens the enclosure for better performance.
  • 15-1/2 X 17-1/2 perforated aluminum grille included.
  • All mounting hardware and isolation pads included.
  • CSW155 SPEX optimization card included with SWA500 amplifier.
