Polk Audio 620-RT (Ea) High Performance In-Ceiling Loudspeaker Overviews

Just like Matthew Polk's Signature Reference Theater (Srt) system, the components used in the Rt Series advantage from Dynamic Balance, a technology which came out of a joint explore task in the middle of Polk Audio and Johns Hopkins University. This laser imaging explore enabled Polk to view on a microscopic level the whole vibrating outside of a driver or tweeter. By this method Polk was able to scrutinize the resonances, which build on speaker cones as they move. These resonances are the root cause of frequency response distortions.

As an x-ray enables a physician to scrutinize the root cause of a indication of illness and designate the right rehabilitation 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. The advantage of Dynamic equilibrium is the dramatic improvement in the sound quality of our speakers, which every listener can appreciate. You no longer have to choose in the middle of perfect bass and smooth, clear midrange. Now you can have it all thanks to Dynamic equilibrium technology.

A crossover is the part of the speaker system, which directs high frequencies to the tweeter and lower range frequencies to the woofer. But crossovers can generate distortion, called phase shift, which reduces clarity and degrades the quality of the speaker to generate a life-like spatial image. Thanks to Dynamic equilibrium technology, the response of Polk's mid-woofers remains literal, at much higher frequencies than accepted drivers. This allows Polk to place the crossover frequency above the range where your ear can most authentically detect phase shirt (the valuable midrange). The corollary is clarity and imaging so outstanding that the speakers seem to melt away. You'll feel as if you're at a live carrying out or authentically on the movie set.

And the corollary of all these technologies? One listen will tell you. You
