Polk Audio was founded by three people who have "golden ears" for good sound. Mathew Polk, George Klopfer and Sandy Gross joined efforts to create a loudspeaker company that is dedicated to crafting high quality, great sounding loudspeakers for the public. With the creation of The Monitor Series in 1972, the company got their start in a two story house outside of Baltimore, Maryland. In 1974 the Monitor 7 was released and Polk Audio started to become a well know name in the audiophile industry. Since their first successful loudspeaker they have established a reputation of producing quality products. Now, the company holds over 65 patents for new technology in audio design. Music has always been their passion and creating practical audio solutions is their mission.The Polk Audio brand has made resounding waves in the car audio industry. They feature an expertly crafted line of full-range speakers and component speaker systems for premium sound. The Polk subs are a hot seller with their flashy metallic look and loud bass reproduction. Check out their top notch line of car amplifiers, perfectly designed to power your subwoofers.
