By keeping the power source separate, Polk Audio engineers built long-term reliability and functionality into the CSW Series Subwoofers: no need to open walls for tweaks or system upgrades. For peak performance, the SWA500 Digital Power Amplifier is custom engineered to power the CSW Series Subwoofers (up to two at a time). Achieve rafter-shaking bass at lifelike volume level with 500 Watts of cool-running, Class D Digital power (4 Ohms at 0.01% THD). Easy-to-reach controls and a compact size make the SWA500 an easy addition to any equipment stack.
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.
