 The Polk Audio LSi7 is a high definition bookshelf speaker that comes with real wood ebony or cherry sides. It was designed for high definition formats which include SACD and DVD-Audio.  The 5 1/4" Dynamic Balance driver has an Aerated Polypropylene cone which provides a wider response and reduces the amount of distortion in the sound. The Ring Radiator tweeters are claimed to be rare in speakers in this price range and they serve the purpose of extending the frequency response, reducing distortion, improving sound dynamics and emphasizing the detail in the sound. It has dual bi-ampable gold plated 5-way binding post inputs that ensure the security of the connections. A mylar bypass capacitor flattens and extends high frequency response while the inert 1-1/2" thick enclosure makes sure that the only thing heard is the music. The Polk Audio LSi7 is provided with magnetic shielding to allow it to be placed near sensitive electronic equipment without any worry of interference.
