Explosive Performance for Movies and Music

The PSW404 is designed for mid-sized rooms and makes a great addition to home theater or stereo systems. It shakes out all the thrills and chills in your favorite movie soundtracks, and its accurate musicality will make you sit up and take notice whether you listen to Lenny Kravitz, or the London Symphony Orchestra.

The PSW404 Features

  • Real wood veneer finish
  • Slot Load Venting improves bass response. The wide, long Slot Load Vent dramatically lessens turbulence, noise and distortion, pouring out a tidal wave of precise, thunderous bass!
  • Polk subs sound better because they're built better. Rock-solid MDF construction (including a 1 inch thick front baffle) suppresses enclosure panel resonance for distortion-free, accurate response.
  • Big 10 inch Long Throw Driver for longer excursion and better linearity.
  • Huge Hi-Roll Surrounds that support their longer excursion.
  • Most powered subwoofers are good for just gut-rumble and boom. Polk understands that you listen to music too so our subs are tight, precise and accurate.
  • High current 200 Watt Continuous (375 Watt Dynamic) power amplifier.
  • Adjustable low pass crossover, phase switch and volume control allows perfect blending with any main speaker.
  • Auto on/off circuit that automatically turns your subwoofer on when it senses a program signal. When no signal is present, the amplifier turns off within 15 minutes
  • Unfiltered LFE input for use with low pass filtered subwoofer output jacks
  • Magnetically shielded for safe, flexible placement next to a TV or video monitor.
