The SubSeries 200 Subwoofer is an energy efficient subwoofer powered by a custom-designed NAD amplifier in a small-scale design. In addition to PSB Speakers "smart bass" limiting circuitry, the SubSeries 200 offers extensive musicality and high-powered bass impact. The deceivingly compact design and trim cabinet provide equivalent SubSeries power in a small, highly developed package. The powerful NAD Class D discrete MOSFET amplifier uses less energy to produce more power reducing standby power to an industry low. Capable of 200 watts of continuous power and dynamic peaks of 560 watts, this is one potent sub!
