Deep Bass, Small Footprint

The PSW111 packs all the power of Polk Audio technology into just a little over a square foot. Experience the strongest bass you'll ever feel in one of the smallest subwoofers you’ll ever find.

Dynamic Balance®

Unique driver materials, speaker geometry and construction techniques produce clean, crisp sound and effortlessly big bass, especially when you need it most.

Klippel Distortion Analyzer

State-of-the-art optimizations to the motor structure, voice coil alignment and suspension ensure the best, most efficient performance at all volumes.

Innovative Features

Smart circuitry, superior compression and an intelligent amplifier deliver highly efficient bass with low distortion and enhanced blending.

Expertly Crafted

Heavy-duty MDF construction ensures perfect volume and distortion-free low frequencies, while eliminating internal standing waves and performance-robbing resonances.

Unique Configuration

Specially-tuned, downward-firing ports produce maximum bass impact and keep the cabinet's front profile as sleek as possible.


PSW Series subwoofers blend perfectly with systems made up of other Polk Audio loudspeakers, such as TSI, RM and R/T/M Series speakers.
