Bass Performance That's Out of Sight

The CSW155 combines stealth convenience with incredible technology to rival the performance of many free-standing, floor-cluttering subwoofers. With one of the shallowest drivers ever engineered (a Polk Audio exclusive), this subwoofer produces air-moving, room-filling bass, while disappearing behind an included perforated aluminum grille (15 1/2" x 17 1/2") that looks like an "air conditioning return" vent. Deep and musical, it's professionally matched to other Polk Audio loudspeakers, allowing you to build the home theater of your dreams in new construction or even in existing walls (60" H x 14" W x 3 3/8" D).


  • The CSW subwoofers fit easily within standard joist spacing.
  • Single 10-inch diameter drivers are matched to meet specific shallow-depth performance
  • guidelines for each subwoofer enclosure.
  • Klippel Distortion Analyzer
  • By using state-of-the-art Klippel distortion analysis, Polk engineers have optimized
  • the subwoofer’s motor structure, voice coil alignment and suspension for the best possible performance and low distortion even at extreme listening levels in the shallowest of install spaces.
  • Neodymium motor structure (in the extra-shallow CSW155 model) makes shallow-depth high performance possible, without sacrificing an ounce of deep bass.
  • Cast aluminum baskets are rigid and inert to suppress resonance.
  • Massive 2-inch voice coils for high bass output and high power handling.
  • Highly durable inverted roll surround maintains “springiness” over the long life of the subwoofer.
  • Dual spiders ensure extraordinary linear excursion and prevent the driver from ever bottoming out, even at tremendous volume levels.
  • Rigid MDF enclosures create shallow-depth structures that eliminate resonances for tighter, more musical bass.
  • Complete mounting hardware and special isolation pads are included.
  • Requires SWA 500 Amplifier.


  • Installs Easily between standard 16" OC (on-center) studs.
  • Long-Throw 10" Polycomposite Subwoofer Driver.
