Explosive Performance For Movies And Music

If you're looking for clean, high output bass in your mid-sized to large room (and who isn't?), this is the perfect powered subwoofer for you. Its massive dual 10" drivers pound with nearly 50% more surface area than a single 12" driver. The PSW650 delivers all the power and gut-rumble you expect from a home theater sub, and is also fully capable of conveying all the depth and musicality of a plucked string bass. Quite nicely, we might add. It also gives you the control you crave. Its volume, crossover frequency and phase controls allow you to fine tune it to match your room, and your taste. And the inclusion of both line level and speaker level inputs allow easy hook-up to any system.

  • Two 10 inch direct radiating subwoofer drivers -- nearly 50% more surface area than a single 12" driver -- for deep bass, smooth response and low distortion
  • Dual Power Port bass ports for deep bass and high acoustic efficiency with low distortion
  • High current power amplifier (165 Watts Continuous, 250 Watts Dynamic)
  • Subwoofer volume control, variable crossover control and phase switch allow you to optimize performance to match your audio system, room acoustics, and program material
  • 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
  • +3dB bass boost switch provides increased output when connected to electronics with low output subwoofer output jacks
  • Unfiltered LFE input for use with low pass filtered subwoofer output jacks
  • Speaker and line level inputs
  • 80Hz High-pass filter on both line level and speaker level outputs
