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.
