King of the Deep
The PSW125 is the King of the PSW Series. The end-all, with a powerful 12-inch composite woofer driven by a high-power intelligent amplifier (150W continuous/300W peak!). The best subwoofer for big rooms and big systems, the PSW125 delivers smooth, musical bass at lifelike volumes; it’s truly groundbreaking.
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.
Unique driver materials, speaker geometry and enclosure construction techniques that actually produce cleaner, clearer sound is at the heart of our patented Dynamic Balance® process. This process helps the PSW125 perform effortlessly in high stress, big bass situations when you need them most.
PSW Series subwoofers outperform the competition with durable, resonance-free Dynamic Balance driver materials that stay stiff and move fast. so you experience deep, musical low frequencies and thrilling effects with superior system blending.
Our state-of-the-art Klippel distortion analyzer optimizes 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.
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.
