CSW155
High Performance Built-In Subwoofer
60″ H x 14″ W

The In-Wall Sub That Outperforms Many Freestanding Subs

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 a camouflage “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).

CSW155 Features:
Installs Easily between standard 16″ OC (on-center) studs.
Long-Throw 10″ Polycomposite Subwoofer Driver.
The shallowest driver ever engineered by Polk Audio, for superior performance in only 3 3/8″ of enclosure depth.
Patented Dynamic Balance Construction uses laser interferometry to tune out performance-robbing resonances before you hear them.
Inverted Roll Surround for long life in demanding in-wall environments.

Inert Cast Aluminum Basket Suppresses Resonances.

Powerful Neodymium Motor Structure for exclusive shallow design with maximum “throw.”
Dual Spiders ensure smooth linear excursion and prevent “bottoming out.”
2″ Wide Voice Coil for high power-handling and massive bass.
Klippel Optimized coil alignment for extraordinary efficient shallow-depth motor action even at lifelike volume.
Rigid MDF Slot-Ported Enclosure, stiffened and reinforced with steel plates.
Perforated Aluminum Grille Included (15 1/2″ x 17 1/2″).
Heavy-Duty Mounting Hardware and professional anti-rattle isolation pads included.
Powered For Optimum Performance by the SWA500 digital amplifier, available separately.
CSW Series Built-in Subwoofers are remotely controlled by the SWA500 Amplifier (sold separately), which fits conveniently into any equipment rack, so the subwoofers can be tweaked for optimum performance quickly and easily. Plug-in SPEX data cards for each CSW Subwoofer model are included, and automatically download preprogrammed equalization, infrasonic filter characteristics and power-output best matched to your subwoofer. The SWA500 also allows for custom optimization to build on these basic elements and ensure the best performance in your space. The SWA500 Amplifier is a BASH amplifier, combining the fidelity of conventional Class A/B amplifiers with the efficiency of Class D amplifiers. It achieves high power (500 Watts continuous into 4 Ohms!) and cool, reliable operation for epic bass with precise definition and low distortion.

Superior Polk Audio Technologies

Dynamic Balance®-A Polk perfected method of analyzing a speaker’s microscopic behavior with laser Interferometry. Polk engineers can tune out unwanted resonance and distortion with the right combination of materials, geometry and construction techniques. This brings you pure, distortion-free sound.
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 bringing you the best possible performance even at extreme listening levels.
