More Bass. Less Space.

No home entertainment system is complete without a powered subwoofer. Discover the extra thrill that deep, clean, high impact bass will add to your system. The new Polk PSW140 powered subwoofer is ideal for movies and music-it delivers deep, powerful bass impact for home theater, and captures all the detail and musicality when reproducing anything from a bass guitar to a concert kettle drum. The Polk PSW140 subwoofer not only offers great bass at an affordable price, it offers plenty of placement options-in an entertainment center, behind furniture or next to a sofa or chair. And it's loaded with an array of convenience and performance features. It's hard to believe such a high quality, full- featured subwoofer can be offered at such an affordable price.

The PSW140 features:

  • 10" direct radiating subwoofer driver for deep bass, smooth response and low distortion.
  • Dual bass ports for deep bass and high acoustic efficiency.
  • High current 180 watt (Dynamic Power) power amplifier.
  • 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 mute circuit that automatically turns your subwoofer on when it senses a program signal. When no signal is present, the circuit mutes the subwoofer.
  • Line level and speaker level inputs
