Tower speakers with built-in powered subwoofers
If you "really want deep bass, want a speaker for music and home theater purposes, or want maximum dynamic range for orchestral, jazz, and rock, go with the LSi25," advises reviewer Anthony H. Cordesman (The Absolute Sound, April/May 2002). Why is this speaker so highly recommended? Because the LSi25, along with delivering stunning audiophile-quality sound, also boasts a powered subwoofer in each tower.
Crystal-clear highs and smooth mids
Polk's Ring Radiator tweeter produces crystal-clear highs.
A big part of the LSi25's incredible sound is the 1" Ring Radiator tweeter. This sophisticated tweeter reproduces highs beautifully, for transparent, natural sound. The LSi25 also comes with two 5-1/4" aerated polypropylene Dynamic Balance® mid/bass drivers. These drivers team up with Acoustic Resonance Control (ARC) technology, for vocals and midrange that come alive in your room. And Polk has devoted a lot of attention to cabinet design, so that unwanted resonances are eliminated — your sound stays smooth and clear. Finally, the anti-diffraction grilles help bring you a wide-open soundstage with pristine imaging.
Save your floor-space with a built in subwoofer.
Clear, punchy bass
Polk's packed a 150-watt RMS amplifier into each LSi25 tower; each amp drives a 10" Dynamic Balance® woofer, to provide ultra-responsive bass with precision and punch. Power Port venting makes your bass even more expansive — it's rare to hear lows this intense from a tower speaker.
Works well in either a stereo or multi-channel setup
Other details include two sets of gold-plated 5-way binding posts for biamping or biwiring, and adjustable spikes for carpeted or hardwood floors. When it comes to home theater, a powerful performer like the LSi25 is hard to beat. Start with an LSi25 pair as front left and right speakers, and other LSi speakers to round out your multichannel setup.
