Any movie fan will tell you that surround speakers are an integral part of recreating the movie theater experience in your home. Polk's LSi M 702 f/x speakers is designed just for that purpose. Building upon the widely acclaimed LSi family of speakers, the new LSi M series incorporates the latest developments in speaker technology. The 702 f/x speakers excel at delivering the kind of wide, deep rear soundstage that puts you in the action. You'll also notice realistic details like the zing of bullets rushing past or the rustle of leaves
Like the larger, floor-standing LSi M models, these surround speakers each feature Polk's Dynamic Sonic Engine. Made up of a 3-1/4" midrange driver and a 1" ring radiator tweeter in its own acoustically sealed enclosure, this tightly spaced duo acts like a "mini-monitor." The precise alignment of the midrange and tweeter allows them to disperse sound over a wide, uniform area with excellent off-axis response in the critical 200 Hz to 2,000 Hz midrange.
The ring radiator tweeter features several improvements from the version in the earlier LSi line. A slight reshaping of the tweeter's bullet-shaped phase plug allows it to move even farther out of the baffle, while a redesigned diaphragm has made the tweeter even more efficient. It even has its own tuned enclosure within the Dynamic Sonic Engine. These changes result in higher power handling, extended dynamic range, improved dispersion and extended high-frequency response - all the way up to 30,000 Hz.
