Polk Audio was founded by Matthew Polk, George Klopfer and Sandy Gross in 1972. The three first met one another while attending classes at Johns Hopkins University in Baltimore. After graduating in 1971, the team collaborated on producing a sound system for a local bluegrass music convention. Polk designed the speaker system, and Klopfer built the cabinets. After it was discovered the producers of the convention could not afford the system, Klopfer designed a logo for Polk Audio and attached it to the speakers. Gross organized the marketing of Polk Audio and helped build Polk's worldwide dealer network.
