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 reasonable prices.
They did so by applying scientific principles
to speaker design and by concentrating sole-
ly 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 now 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 innova-
tive, high-quality design. Polk Audio speakers
are sold in over 50 countries and in audio/
video specialist retail locations throughout
the U.S.
Founders Matthew Polk and George Klopfer
still work alongside 300 dedicated Polk team
members to bring you the best speakers you
can buy.
