Let's start with critical appreciation: respected reviewer Anthony H. Cordesman writes, "The LSi15 has an extraordinary mix of treble and midrange performance for the price. The upper octaves are among the smoothest and most detailed at all levels of dynamics that I have heard; they certainly outperform most speakers costing more than twice as much" (The Absolute Sound, April/May 2002). We couldn't have said it better ourselves.
Crystal-clear highs and smooth mids
Polk's Ring Radiator tweeter produces crystal-clear highs.
A big part of the LSi15's audiophile-quality sound is the 1" Ring Radiator tweeter. This light, extremely responsive tweeter won't color your music your highs sound as close as possible to the original. The LSi15 also offers two 5-1/4" aerated polypropylene Dynamic Balance® mid/bass drivers, along with Acoustic Resonance Control (ARC) technology vocals and midrange have never sounded so real. The 8" Dynamic Balance woofer and Power Port venting deliver accurate, room-filling bass that goes all the way down to 32 Hz. And a superb cabinet design helps eliminate resonances, so your sound stays smooth and clear. Whether you're enjoying the intricate textures of jazz or chamber music, or the simple purity of a solitary vocalist, the LSi15 will astonish you.
Great for home theater or stereo music setups
Other details include two sets of gold-plated 5-way binding posts for biamping or biwiring, and adjustable spikes for carpeted or hardwood floors. And don't forget with all that sonic richness and precision, a pair of LSi15s make formidable front left and right speakers in a home theater system, too.
