POLK SWA 500

Polk Audio SWA500 Power amplifier for Polk CSW in-floor subwoofers. The SWA500 is custom engineered to power Polk Audio’s CSW Series of built-in subwoofers to rafter-shaking, distortion-free levels. The SWA500 comes with custom sound-shaping circuit cards for each of the CSW subs. Plug in supplied SPEX circuit cards to optimize the amplifier to match the specific subwoofer model being used. Custom frequency shaping (programmed into SPEX card) results in deep, hard-hitting, and distortion-free bass.
The SWA500’s standard chassis width lets you stack it neatly with your other audio/video components, or you can hide it away in a cabinet to reduce room clutter. This stable amplifier can also power a pair of either the CSW100s or CSW200s, for deepest, more accurate bass performance.
