About the PSW-650

The Polk Audio PSW-650 is a high-performance powered subwoofer equipped with two 10-inch direct radiating subwoofer drivers with rubber surrounds, positioned on the side panels for enhanced bass output. It features a 165-watt RMS amplifier (some sources note a high-current 250-watt amplifier) and dual Power Port bass ports that provide deep bass with high acoustic efficiency and low distortion. The subwoofer offers a frequency response range of 28-125 Hz (-3 dB) and a continuously variable low-pass crossover frequency adjustable between 40-120 Hz. It includes multiple input options: preamp-level inputs, speaker-level inputs and outputs, and a dedicated unfiltered LFE input for 5.1 bass. Controls include a phase switch, bass boost (+3 dB), and volume control. The enclosure is bass reflex type with a glossy black or black woodgrain finish, measuring approximately 18 3/4" H x 17 1/2" W x 18 3/4" D. The PSW-650 features an auto on/off circuit that powers the subwoofer on when a signal is detected and off after 15 minutes of inactivity. It is well-regarded for its musical, punchy, and tight bass performance suitable for medium to large rooms and blends well with small main speakers. Warranty coverage is 3 years on electronics and 5 years on the loudspeakers.
