PSW303

Powered Subwoofer

Available Finishes:

Explosive Performance For Movies And Music

Robust (adj.) 1. Full of strength, vigorous. 2. Rich and full. Bingo. Mid-sized room? Need big bass, but don't need a subwoofer that's as big as your couch? Try the PSW303. 100 watts of continuous power move the beefy high excursion 8-inch driver with incredible bass and accurate musicality. Its modest size makes it easy to place in a cabinet or behind furniture for unobtrusive high performance. (Unobtrusive (adj.) Not noticeable.)

PSW303 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 8 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 100 Watt Continuous (260 Watt Dynamic) power amplifier.
  • Adjustable lowpass 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.
