affordable, high performance speakers



About Polk Audio

Since 1972, Polk has remained faithful to their original goal of building true high-performance speakers that regular people can afford. They have eschewed gimmicks and sonic exaggerations in favor of natural sound and accurate reproduction and customers have remained loyal to the brand.

Walk the halls of Polk Audio's Baltimore headquarters, and you'll meet sales people, engineers and technicians who also happen to be musicians, audiophiles, home theater mavens, tube-equipment fanatics and rare vinyl LP collectors. For the folks at Polk Audio, designing audio equipment is not just a job, it's a passion. And they wouldn't have it any other way.
