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 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 innovative,
high-quality 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.

The Story of Dynamic Balance

®

Your new Polk speakers employ Dynamic Balance, a technology which came out of a joint
research project between Polk Audio and Johns Hopkins University. This laser imaging
research enables us to view the entire vibrating surface of a driver or tweeter, allowing us to
observe the resonances which develop on speaker cones as they move. These resonances are
the root cause of frequency response distortions.

As an x-ray enables a physician to discover the root cause of a symptom and thereby pre­scribe the right treatment for a cure, this laser imaging technique allows Polk engineers to
find the right combination of high-tech materials, geometry and construction techniques to
tune out the offending resonances. The benefit of Dynamic Balance is the dramatic
improvement in the sound quality of our speakers, which every listener can appreciate. You
no longer have to choose between excellent bass and smooth, clear midrange and highs.
Now you can have it all, thanks to Dynamic Balance technology.

Polk “Dynamic Balance”

low distortion

Laser Interferometry tests produced holographic “photos” of drivers

in motion. The “bad” drivers are experiencing modal breakup that

results in performance-robbing resonances. A “perfect” driver would

look like a cake (flat on top), more, like the photo on the right.
