Polk Audio® 10" Subwoofer-Cherry

• Heavy-duty MDF enclosure 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.
• 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. It means PSW subwoofers 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. 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, and superior compression circuitry limits distortion at extreme volume levels.
• 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.
