SW-1  

Subwoofer Amplifier with DSP

The SW-1 is designed to provide not only 90% amplifier efficiency delivering 370-watts of subwoofer driving power, but also the necessary DSP required for all Wisdom Audio RTL subwoofers. Each SW-1 is programmed for use with a specific subwoofer model and is not capable of supporting different subwoofer models simultaneously. The desired crossover frequency between the loudspeakers and the SW-1 is handled upstream in a surround processor.
