Polk Audio is an award-winning manufacturer of high-quality audio products and the largest audio brand in the Sound United group. Founded in 1972, Polk Audio is the market leader in home theater speakers in North America and a leading manufacturer of soundbars, headphones, wireless speakers, portable and watercraft speakers, as well as amplifiers and other high-quality audio products. In 1971, Matthew Polk, George Klopfer, and Sandy Gross were friends and college classmates that shared a love for physics, engineering, and music. They teamed up to build a sound system for a local bluegrass music convention, but after they discovered there weren’t enough funds to pay them, they decided to design and attach a logo to the system. Polk Audio was born. In 1972, the Polk Audio headquarters were established on a quiet overgrown street in Baltimore. Their love for music inspired them to design and build a loudspeaker that not only sounded better than what was available at the time but was more practical. Focused on bringing concert quality sound into homes, the Monitor Series was introduced in 1972, forever changing the home audio paradigm and setting the standard for performance and value. Polk Audio is owned by Masimo Consumer.
