Just like Matthew Polks Signature Reference Theater (SRT) system, the components used in the RT Series benefit from Dynamic Balance, a technology which came out of a joint research project between Polk Audio and Johns Hopkins University. This Laser imaging research enabled Polk to view on a microscopic level the entire vibrating surface of a Driver or tweeter. By this method Polk was able 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 prescribe the right treatment for a cure, this laser imaging technique allowed Polk engineers to find the right combinations of high tech materials, geometry and construction techniques to...
