Polk Audio PSW108 10" Powered Subwoofer - 100W Active Home Theater Sub - Good Condition

Up for sale is a used Polk Audio PSW108 10" Powered Subwoofer.

An absolute classic addition for rounding out a home theater surround system, upgrading a gaming rig, or adding rich low-frequency depth to a traditional 2-channel vinyl stereo setup. The PSW108 is engineered around a front-firing 10" Dynamic Balance® polymer composite woofer paired with a front-panel flared bass port. This architecture maximizes punch and efficiency while heavily dampening cabin distortion, allowing the sub to drop down to a deep $35\text{ Hz}$ frequency response.

Driven by a built-in high-current amplifier pushing 50 Watts RMS / 100 Watts Dynamic Peak Power, this active subwoofer seamlessly blends into your existing system. The rear interface includes variable crossover controls ($80\text{ Hz} - 160\text{ Hz}$), a 0/180-degree phase toggle, and both line-level (RCA) and speaker-level spring-clip inputs, ensuring universal compatibility with vintage stereo receivers and modern AV systems alike.

Condition Notes:

This subwoofer is in Good Used Condition and operates flawlessly.

• Performance: Fully audio-tested. The internal Class-D amplifier module runs cool, the 10" driver foam surround is fully intact, and it produces a tight, authoritative low-end thump without any port chuffing or cabinet rattles.
• Cosmetics: Shows standard, honest signs of typical home shelf use and handling over the years. There is minor surface scuffing visible across the top plate and side panels. The bottom edge where the feet sit shows slightly heavier scuffing from being placed on hardwood floors, but there are no deep gouges or structural cracks. The front fabric grille is fully intact (please see all detailed photos).
