Finally an in-wall sub that out-performs many free-standing powered subwoofers!
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.
SWA500 Amplifier (sold separately)
The CSW155 is powered by an external 500-Watt Class D amplifier, the SWA500 (sold separately). The bottom line is high power and cool, reliable operation, with precise definition and low distortion. The SWA500 is supplied with a SPEX Card that plugs into the SWA500 to pre-program equalization, infrasonic filter characteristics and power output of the amplifier to optimize its performance for the CSW155. Each SWA500 can power up to two CSW155s.
The numbers don’t lie. The CSW155 delivers more deep and ultra deep bass than many free-standing models!
