Description
When it comes to surround sound, a center channel speaker has to be able to pull its own weight — and then some! After all, the center channel is responsible for most of the dialogue and on-screen effects in a movie soundtrack — and often carries the burden of voices and instruments in multichannel music, too. Up for sale here is Polk Audios once flagship (top-notch) LSiC center channel speaker, with critically acclaimed LSi design and a frequency response of 52-26,000 Hz, extraordinarily well-prepared for the job!Polks Ring Radiator tweeter produces crystal-clear highs.Innovative design for exceptional soundThe LSiC boasts two 5-1/4 aerated polypropylene Dynamic Balance® drivers with ARC and Power Port technology: you get the same sumptuous mids and lows found in other LSi speakers.

The ring radiator contains a series of innovations in tweeter design that make it able to deliver flat response at high dynamic flat responses at high dynamic levels without breaking up, and that means openness and clarity of detail without stridency or harshness. This minimal-distortion tweeter is able to capture details at high or low levels that signify spatial cues. Such measurable performance translates to the presentation of a wide and deep sound stage, at any listening level, with a high degree of stability. The ring radiator is the speaker designers ideal, a tweeter that displays exceptional dynamic range without distortion or losing focus or resolving power. Something that everyone has been desiring and left wanting when listening to the old standard issue dome silk tweeter: a flat, accurate, loud tweeter. One clue to its performance is that while many tweeters require a 3 circular cutout on a baffle board, the ring radiator requires a 4 cutout - meaning what youre getting is a nearly 7 area magnet for a 3 hole, and slightly more than a 12 area magnet for a 4 hole. So, while only 25% larger in area, the magnet may be nearly twice as strong! These are the little things you notice while reading the spec sheets on various tweeters! LOL. As you might imagine, for a voice coil of approximately the same diameter, bigger, stronger magnets usually generate greater control. John Atkinson, Stereophiles editor and resident audio engineer, after testing (in March 2003!) the LSi7s tweeter performance, described it as superbly clean over most of the region shown. Just jumping into the audiophile game, and dont want to break the bank? These Polk Audios served me well, and they sound AWESOME still today! For a very very reasonable, low cost of entry. These things punch way above their price point, sounding as good and often better than speakers that cost twice the original retail price (these cost $820 per pair when they came out!).
