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 expansive 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.
