Product Description
Amazon.com Product Description
The 150-watt LSi7 high-definition bookshelf loudspeakers add superior musical accuracy and a serious theatrical impact to any home theater system. Inside the sculpted, real wood cabinet is a single, 5.25-inch Dynamic Balance driver with a resonance-suppressing aerated polypropylene cone for wide response and low distortion. Polk's Dynamic Balance technology produces flat frequency response, sharp detail, and an ability to play program material with wide dynamic range at life-like volume levels without a hint of strain. The sound is always clean, clear and effortless. Cast aluminum driver baskets resist flexing for tight bass and coloration-free midrange.
The 1-inch ring radiator tweeters in the LSi7 speakers provide extended frequency response, low distortion, excellent dynamics, and superior detail and transparency. The tweeter's ultra-light woven diaphragm is supported at two pivot points, with the voice coil attached between the two points. With very little unsupported material, there's less opportunity for performance-robbing resonance to develop. A mylar bypass capacitor in the high-pass crossover extends and flattens high frequency response so you hear musical details found in high definition formats such as SACD and DVD-Audio.
Rear-firing patented Power Port vents built into the back plates provide distortion-free bass and double as convenient wall-mounting brackets. This venting extends and strengthens the speaker's lower-midrange performance for a seamless blend with a subwoofer. The dual, front-mounted Acoustic Resonance Control (ARC) port system reduces unwanted internal enclosure resonance for clear midrange reproduction, eliminating unnatural thickness to voices. Also, the LSi7 speakers are timbre-matched with the LSi Series, for a seamless, realistic surround sound experience.
Dual (bi-ampable), gold-plated five-way binding post inputs provide secure wire connections and versatile wiring options.
