RING RADIATOR TWEETER

The Ring Radiator Tweeter, usually found only in speakers costing thousands more than Polk speakers, gives the LSi Series its incredible accuracy and astonishing detail, to reveal the nuances of your favorite CDs, high definition discs and LPs. The ultra-light woven ring radiator diaphragm is supported at two hinge points (A & B) and is driven by a centrally positioned voice coil (C). With a higher ratio of supported material than conventional tweeters, there’s less opportunity for performance-robbing resonance to develop. This remarkable tweeter delivers accurate high frequencies with precise detail and wide dispersion. See more about The Ring Radiator at www.polkaudio.com/catalog/technology/.
