By keeping the power source separate, Polk engineers built long-term reliability and functionality into the CSW Series subwoofers: no need to open walls for tweaks or system upgrades. Peak performance is delivered via the SWA500 digital power amplifier, which can power up to two CSW Series subwoofers at a time.
The Power Behind Our CSW Built-in Subwoofers
CSW built-in subwoofers are powered by an external class D amplifier, the SWA500. It produces 500W continuous into 4 ohms. The BASH amplifier combines the fidelity of conventional class A/B amplifiers with the efficiency of class D amplifiers. The bottom line is high power, and cool, reliable operation with precise definition and low distortion. Plug-in data cards for each subwoofer, called SPEX cards, preprogram equalization, infrasonic filter characteristics and power output that best matches the subwoofer being used. Each SPEX card also custom install subwoofers/amp has specific power control circuitry tailored to each subwoofer’s requirements for an even greater level of reliability.
