About the PSW-505

The Polk Audio PSW-505 is a powered subwoofer featuring a 12-inch front-firing, long-excursion polymer composite driver with a high-roll surround, magnetically shielded for safe placement near video equipment. It includes a 300-watt continuous RMS amplifier (460 watts dynamic) and a bass reflex enclosure with slot-loaded venting to reduce turbulence and distortion. The frequency response ranges from 23 Hz to 160 Hz overall, with a -3 dB range of 28 Hz to 125 Hz. It offers a continuously variable low-pass crossover adjustable from 60 to 120 Hz with a 24 dB/octave slope, a phase switch (0/180 degrees), and volume control for blending with main speakers. Inputs include unfiltered LFE RCA input, filtered line-level RCA inputs, and speaker-level 5-way binding posts with outputs. The subwoofer has an auto on/off circuit that powers the unit on when signal is detected and off after 15 minutes of no signal. The enclosure is constructed from solid MDF with a 1-inch thick front baffle to minimize resonance. Dimensions are approximately 18.19" H x 15.13" W x 18.28" D, weighing about 43 lbs (19.5 kg). It comes with a 5-year warranty on the woofer and 3 years on the amplifier. The PSW-505 is designed for both music and home theater applications, delivering tight, precise, and accurate bass performance.
