Polk Audio PSW350 10″ Powered Subwoofer – 260W Dynamic

The Polk Audio PSW350 is a compact, full-featured powered subwoofer designed to add clean, high-impact bass to music and home theater systems without dominating your room visually. This example is in very good condition with a black matte finish and has been fully tested to confirm strong output and proper operation.

At its heart, the PSW350 uses a 10″ front-firing Dynamic Balance woofer driven by a high-current 100-watt RMS amplifier (260 watts dynamic), giving it enough headroom to deliver punchy, room-filling bass in small to medium spaces. The enclosure is a direct-radiating, vented design with dual rear-firing ports to extend low-frequency response while keeping distortion low. Overall frequency response is rated from 25 Hz to 180 Hz, with a ‑3 dB range of 38–160 Hz, making it a capable match for bookshelf and tower speakers alike.

On the back panel you’ll find flexible connection and control options: speaker-level inputs and outputs, stereo line-level inputs, and a dedicated unfiltered LFE input for use with modern AV receivers that provide their own bass management. A continuously variable low-pass crossover (60–160 Hz), phase switch, and level control make it straightforward to blend the PSW350 with your mains. The auto on/off feature powers the subwoofer up when it senses signal and puts it into standby after a period of silence, adding convenience in daily use.
