Product Description
Polk Audio 620-RT (Ea) High Performance In-Wall Loudspeaker: Electronics. Just like Matthew Polk's 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. By this method Polk was able to observe the resonances, which develop on speaker cones as they move. 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 tune out the offending resonances. These resonances are the root cause of frequency response distortions.
