Daniel J. Hodgson, Polk Audio's Senior Vice President, was very enthusiastic about the $3000/pair LSi25, a floor-standing, 3-way loudspeaker."It has a 1" VIFA ring-radiator, dual-pivot tweeter to increase dispersion," said Daniel. There are two midranges that surround the tweeter in D'Appolito configuration, and a powered 10" sidefiring subwoofer. The drivers have cast speaker baskets with aerated-polypropylene cones. He went on to point out the two small ports on the front baffle next to the midrange. "These two small ports are designed to eliminate resonance, which our company calls Acoustic Resonance Control," added Michael Cooper, Florida Regional Sales Manager for Polk.
