Magnetically Shielded Powered Subwoofer

Available Finishes:

Explosive Performance For Movies And Music

The performance of this little subwoofer is all out of proportion with its size. Where's all that strong musical bass come from? It comes from a brawny high current amp driving an 8" woofer. The PSW250 easily connects to any system and represents a tremendous value.

The PSW250 features:

  • 8-inch direct radiating subwoofer driver for deep bass
  • Dual flared ports for low distortion
  • High current power amplifier
  • Magnetically shielded for safe placement near your TV
  • 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
  • Adjustable lowpass crossover, phase switch and volume control allows perfect blending with any main speaker.
