Polk Audio PSW Series PSW110 Black High Performance Powered Subwoofer Single

Polk's PSW110 powered subwoofer is the next evolution in powered subwoofers. The compact enclosure is made from non-resonant MDF with 0.75" internal baffling and bracing for rock solid performance with superlative detail and accuracy. The combination of side-firing driver and down-firing port surrounds the room in sound.

The voice coil of the 10" driver is perfectly centered in its magnetic field for deep bass with no distortion. The built in amplifier has a 100W continuous output with 200W of peak power. An overall 32Hz to 250Hz frequency response is attenuated by an adjustable 60Hz to 160Hz crossover so you can tune the output to match the rest of your speakers.

The back panel has both line level and speaker level inputs so you can use the PSW10 with virtually any amplifier. An LFE input allows the subwoofer to receive a precisely tailored signal. There is also a phase switch for additional fine tuning of the sound. The "auto" selection on the power switch lets the subwoofer turn itself off after 15 minutes of no signal and turn itself back an almost instantaneously, leaving you free to enjoy the music and not worry about turning things on and off.
