PSW 505

12" Powered Subwoofer

Dynamic Balance® Woofer Design

Polk perfected the method of analyzing a speaker's microscopic behavior with laser Interferometry. With that information in hand, Polk engineers select the ideal combination of materials, geometry and construction techniques to literally “tune out” unwanted resonance. The result is a subwoofer that delivers pure, distortion free deep bass.

Klippel Optimized Long Throw Woofer

Using a state-of-the-art Klippel Distortion Analyzer, Polk engineers optimized the woofer's motor structure, voice coil alignment and suspension for longer excursion and greater linearity bringing you the best possible performance even at the most extreme listening levels.

Slot Load Venting

Improves bass response. The wide, long slotted vent dramatically lessens turbulence, noise and distortion, pouring out a tidal wave of precise, thunderous bass!

Rock-solid MDF construction

(including a 1 inch thick front baffle) suppresses enclosure panel resonance for distortion-free, accurate response. Polk subs sound better because they're built better.

Why Polk Audio

The real question is, why anything else? We’ve always made the best speakers at the best price - that’s it. 

But for storytelling’s sake, let’s back it up to 1972 where a group of friends, talented engineers, and music lovers got together with the skillset, the ambition to make the best speakers they could afford, and the attitude to change the establishment. That day, a speaker company was born with a clear vision for quality and a powerful mission for value. 

Each and every day since then, all Polk products are the result of tight-knit collaboration, teamwork, and our collective passion to make great sound available to as many people as humanly possible. 

A mission like that requires more than engineering expertise. It requires inventive spirit, hard-earned experience, and intuition. It’s that intuition—the most magical human ingredient—that bestows Polk products their sonic personality and pride of place in your home. To this day, design, acoustics, engineering (and ingenious, intuitive human magic) all happen under one expensive roof under the guise of democratizing sound. Because we mean it when we say great sound shouldn’t be a privilege of the few, it should be accessible and available for all.
