POLK AUDIO – A HISTORY OF EXCELLENCE

Polk Audio was founded in 1972 by Matthew Polk and George Klopfer. Their dream was to
make speakers with the performance of the world’s best speakers, at a reasonable price. They
did so by applying scientific principles to speaker design and by concentrating solely on the
speaker business. That is how Polk became known as “The Speaker Specialists.”

Today Polk Audio is still headquartered in Baltimore, Maryland and is one of the world’s
largest manufacturers of home and car loudspeakers. Polk’s research has yielded over 20
patents for advances in loudspeaker performance and value. Polk speakers have earned the
praise of audio experts the world over, as well as dozens of awards for innovative, high­quality design. Polk Audio speakers are sold in over 50 countries and in audio/video
specialist retail locations throughout the US.

Founders Matthew Polk and George Klopfer still work alongside 300 dedicated Polk team
members to bring you the best speakers you can buy.
