The CSW Series Built-in Subwoofer Systems deliver massive, cinema-sized bass from hidden locations inside your walls or floor. And even if you're retro-fitting an existing room as your home theater or game room, installation is easy either within your existing walls or hidden inside media furnishings.
The CSW155 is for everyone who covets uncompromising bass performance in a nearly invisible package. The CSW155’s single 255mm 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 great reliability in mind.
Please note that this is a Passive Subwoofer. Due to the constraints of the size of the cabinet, no amplification is on board. It will be necessary to use external amplification. Polk Audio's SWA500 Digital amplifier is a perfect match.
