Explosive Performance for Movies and Music

If you're looking for clean high output bass from a small stylish package, the PSW550 is the sub for you. Don't let the modest enclosure and driver size fool you. The 8 inch driver is remarkably robust, featuring a long-throw motor and suspension for deep, loud bass that belies its size. Patented Power Port venting further helps the PSW550 perform like a much larger subwoofer. Bigger subwoofers run and hide when confronted with the dainty but dangerous PSW550.

The PSW550 features:

  • Long-throw 8-inch direct radiating subwoofer driver for deep bass
  • Floor coupled Power Port bass vent for deep bass and high acoustic efficiency with low distortion
  • High current power amplifier
  • Magnetically shielded for safe placement near your TV
  • Stylish high gloss black finish
  • 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
  • Adjustable lowpass crossover, phase switch and volume control allows perfect blending with any main speaker.
