    PSW 125 Features:

    • Heavy-duty MDF construction is designed and engineered for perfect volume, minutely tuned for distortion-free low frequencies, and internally braced and damped to eliminate internal standing waves and other performance-robbing resonances.
    • This unique configuration uses a specially tuned and directed port to produce maximum bass impact, using your floor as more than just something to stand upon. Downward-firing ports also keep the cabinet’s front profile as sleek as possible.

This process helps the PSW 125 perform effortlessly in high stress, big bass situations when you need them most.

    • Our state-of-the-art Klippel distortion analyser optimises the woofer’s motor structure, voice coil alignment and suspension for smooth, unimpeded movement over a broad spectrum of the lower frequencies to ensure the best, most efficient performance even at extreme listening levels.
    • Easily accessible, professional-grade (unfiltered) LFE, line- and speaker-level inputs, and speaker level outputs, allow easy connection to any system.
    • Smart sensing circuitry knows when to turn itself on and off. Superior compression circuitry limits distortion at extreme volume levels. Intelligent amplifier also features adjustable low-pass crossover, phase switch & subwoofer volume controls to professionally control your bass output and the sub’s blending characteristics with your front stage speakers.
    • PSW Series Subwoofers blend perfectly with systems composed of other Polk loudspeakers, especially TSi, RM and R/T/M Series speakers.
    • Unique design keeps your subwoofer stable and steady even at radical volume levels, for more efficient use of power. No more “escaped washing machine” syndrome.
