Top of the Line Tower Performance
The flagship in the tower line with built in 150 watt, 10" powered subwoofer on each speaker. You can skip the external subwoofer (you can add one if you really want to!) Let these speakers be the anchor of your 2 channel system, or your multi-channel surround. Weighing over 80 lbs each, they're built like a tank. Compare them to speakers double their price and you'll see (and hear) how well they hold their own.
LSi Series Features
Adjustable Rubber Feet/Carpet Spikes
On tower models, the feet are adjustable incase your floor isn't as perfect as your speakers. Use the non skid rubber feet on hard surfaces and spikes on carpet.
PowerPort®
Patented* Polk technology is featured on every LSi Series speaker. PowerPort provides deep bass while preventing unwanted air chuffing.
*US Patent 5517573 & 5809154
Ring Radiator Tweeters
These exotic tweeters offer some of the finest highs you'll hear out of a speaker. The ring radiator tweeter is the same one found on ultra-high end speakers that cost more than a car! But with Polk LSi, you can experience its precise accuracy and meticulous detail at a fraction of the price. Learn more about the magic behind the Ring Radiator Tweeter
Ebony or Cherry Side Panels*
Made from real wood veneer instead of simulated vinyl. The side panels bring each side's thickness to 1.5" to further brace the cabinet against unwanted resonances. Best of all they look marvelous.
*except LSiC and LSiFX which have all black piano gloss finish
Cast Aluminum Driver Frames
Other speakers use inferior stamped steel baskets which can flex while playing, muddying up the mids. Not so with LSi series- the midbass drivers use cast aluminum baskets to prevent unwanted flex.
Aerated Polypropylene Drivers with Dynamic Balance
How does LSi sound so warm and natural? The material the speaker is made of has a lot to do with it. Aerated polypropylene is stiff on the outside providing transient response, but "chewy' on the inside providing damping and light mass. Want to learn more about the benefits of this space age material? Click here for an in-depth explanation. Dynamic Balance is a Polk perfected method of analyzing a speaker's behavior at the microscopic level with lasers to tune out unwanted resonance and distortion.
Mirrored Design
Ordinary speakers use the same speaker as the left and right, but higher end speakers such as LSi are mirrored, designated left and right. This brings you perfectly balanced stereo imaging.
Piano Gloss Black Cabinet
The piano gloss black cabinet looks classy and blends in with either antique décor or modern high tech furnishings, but it doesn't stop there. The cabinet is extensively braced killing any unwanted cabinet resonance. Knock on any LSi speaker to give them the knuckle test and feel how solidly they're built.
Magnetically Shielded
All models* are magnetically shielded for safe placement near CRT displays.
*Except LSiFX, but you wouldn't put your surround speakers next to your TV anyway…
ARC Port
Featured in all models*. Unfortunately all speakers have a resonance point that will cause midbass boom causing vocals to sound "chesty." We address this problem head on with patented** ARC Port technology bringing you clear, resonance free midrange. Learn more
*Except LSiFX **US Patent # 5696357
Cascade Tapered Array
Cascade Tapered Array is an advanced crossover configuration providing wider dispersion and greater midrange accuracy on multi-driver speakers. It's only used on higher end speakers. Your mids will sound more natural and every seat will hear spectacular sound. Pretty neat?
Perfectly Matched to LCi In-Wall/Ceiling Speakers
Do you have freestanding LSi front speakers but can't mount surrounds or a center? The perfect solution is to use Polk LCi series in-wall/ceiling speakers. They use the same Ring Radiator Tweeter and Aerated Polypropylene Drivers as their freestanding counterparts. You'll have stealth and a perfectly matching system keeping everybody happy.
Bi-Amp*/Bi-Wire Capable and Premium Connectors
All speaker connectors are gold plated for maximum signal transfer. In addition, you may bi-amp or bi-wire each speaker to further maximize sound quality.
*LSi25 is already bi-amped but may be bi-wired.
