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/.
