Patented Polk Audio technology and construction techniques produce powerful, deep bass performance, especially when you need it most.

Slot-loaded port design, lightweight polypropylene cones and durable rubber surrounds engineered for perfect volume, superior damping and deep, distortion-free bass response.

Proprietary intelligent amplifiers generate minimal heat and need less power to sound great, even at extreme listening levels.

Lower the subwoofer’s intensity quickly and easily—right toggle from the remote control.

Polk Room Optimizer (PRO) features four-way phase selection, four presets and an easy-to-read, blue status LED so you can adjust your subwoofer for optimal performance without leaving your seat.


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.
