Description

Polk Audio PSW10 — A 10-Inch Powered Subwoofer That Suits Almost Any Room

The Polk Audio PSW10 is a compact, popular 10-inch powered subwoofer offering easy setup, flexible connectivity, and a significant bass boost for home theater or music systems at an accessible price point.

The Driver and Cabinet

Built around a 10-inch Dynamic Balance polymer composite cone driver in a front-firing ported MDF enclosure, the PSW10 is designed to add deep, controlled low-frequency reinforcement to any stereo or surround system without demanding significant floor space. The built-in amplifier delivers 50 watts RMS with 100 watts of dynamic peak power, providing enough headroom for movie soundtracks and music with real low-frequency content. Non-resonant MDF cabinet construction with 0.75-inch baffles and internal bracing keeps the enclosure tight and focused, minimizing cabinet coloration and helping the driver stay controlled even at higher output levels.

Connections

Connectivity is straightforward and flexible — stereo RCA line-level inputs accept signals from any receiver or processor with a subwoofer or line-level output, while spring-clip speaker-level inputs allow direct connection from amplifier or receiver speaker terminals for systems without a dedicated subwoofer output. A variable low-pass crossover (80–160 Hz), independent volume control, and a toggle phase switch on the rear panel allow easy integration with a wide variety of main speakers and room placements. Auto on/off circuitry powers the subwoofer up when signal is detected and returns it to standby during quiet periods. This example is in very good cosmetic condition with light signs of careful use and confirmed fully functional.

Why This One

The Polk Audio PSW10 is a well-established entry-level subwoofer that reliably delivers the bass reinforcement that bookshelf speakers and compact towers simply cannot provide on their own, making it a practical and affordable upgrade for home theater or music listening in small to medium-sized rooms. In very good cosmetic condition and fully tested, this is a ready-to-use addition to any system.

Polk Audio began in Baltimore in 1972, founded by Matthew Polk, George Klopfer and Sandy Gross. Its SDA speakers of the 1980s used a cable between the left and right speakers to widen the stereo image. We carry Polk towers, bookshelf speakers, centre channels and subwoofers. We've had more than 180 Polk listings so far, covering more than 80 different models. Every used Polk here is inspected, tested and serviced as required, then photographed in-house and covered by our Bumper-to-Bumper Warranty and Perpetual Trade-Back Program. Looking for new Polk?

Our five best-selling Polk models so far: the RTi10 towers, the PSW10 and PSW125 subwoofers, the RTi4 bookshelf speakers and the CSi3 centre.

The Polk story, 1972 to today

Matthew Polk, George Klopfer and Sandy Gross, graduates of Johns Hopkins, founded Polk Audio in Baltimore, Maryland, in 1972. The Monitor 7 of 1974 was their first model to succeed, and the Monitor 10 followed in 1976.

SDA. In 1984 Polk introduced SDA (Stereo Dimensional Array). A cable between the left and right speakers lets each one cancel the sound that crosses over to the wrong ear, for a wider stereo image.

Growth. Polk went public in 1986 and moved to new premises in Baltimore. It began moving manufacturing to Tijuana, Mexico, in 1988, and by 2012 Stereophile reported that Polk designed in the US and built in China.

New owners. Directed Electronics agreed to buy Polk in 2006. Polk later became part of Sound United, Masimo bought Sound United in 2022, and in September 2025 HARMAN, a Samsung company, completed its purchase of Sound United. The 2018 Legend series brought SDA back.

Which Polk is which?

Monitor (1970s to early 1990s): the Monitor 4, 5, 7, 10 and 12, with A, B and C revisions.

SDA (1984 to about 1991): the SDA-1 and SDA-2 families, CRS, SRS and the later "TL" models.

RTA (1979 to 1992): towers such as the RTA 11t, with two woofers and two passive radiators.

RT and RTi (2001 onward): Polk's lower-priced lines. Our best-selling RTi10 towers and RTi4 bookshelf speakers come from here.

CSi centres and PSW subwoofers: the CSi3 centre and the PSW10 and PSW125 subwoofers are among the Polks we sell most.

LSi (about 2001 to 2010) and LSiM (2011): Polk's flagship lines of that decade, followed by Signature (2016), Legend (2018) and Reserve (2021).

Buying used Polk: what to check

SDA cable. SDA speakers need the interconnect cable between them for the SDA effect, and early SDA models need a common-ground amplifier. Make sure the cable comes with the pair.

Tweeters. Owners report that some SL3000 tweeters on the 1989 to 1991 SDA TL models leaked their ferrofluid and failed, and that Monitor-series pairs may carry mismatched factory or replacement tweeters. Check that every tweeter plays.

Surrounds. Some early Polks used foam surrounds, which rot with age; later models such as the RTA 11t and LSiM use rubber. Press gently on each woofer surround.

Everything we list is inspected, tested and serviced as required here, and comes with our warranty.
