polk technology

DYNAMIC BALANCE®

Advanced laser imaging technology allowed Polk Audio engineers to see the entire vibrating surface of a driver and tweeter; they could actually see the resonance develop on the speaker cones—resonance that is the root

cause of loudspeaker distortion (A). Being able to see the resonance develop, they determined the “DynamicA Balance” of high-tech materials, geometry and construction that effectively tune out the offending resonance

(B). Exclusive Dynamic Balance Composite Material Technology delivers sound that’s effortlessly clean and clear, even at lifelike volume. See more about Dynamic Balance at www.polkaudio.com/catalog/technology/.
