partnered with them to produce the best sound­ing, best looking car speakers ever. They are

of our exclusive sound innovations, like Dynamic Balance®for clean sound and low

well as an exciting new look.

The Story of Dynamic Balance

®

Your new Polk speakers employ Dynamic Balance, a technology that 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 that 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.

Concentric breakup of cone

Radial breakup of cone

Polk “Dynamic Balance”

design results in

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.
