The L820 bookshelf/wall-mount speaker is video shielded and features a PolyPlas; woofer and midrange and a pure-titanium tweeter to deliver accurate performance with dramatically reduced distortion for incredibly realistic sound. The 6 inch woofer delivers excellent bass impact and excitement and the ultrahigh-frequency driver extends response out to 40kHz. Perfect for SACD or DVD-Audio recordings. The tweeter is mounted in our proprietary Elliptical Oblate Spheroidal (EOS;) waveguide for improved high-frequency dispersion anywhere in the listening room. The slim and wall-mountable 5 inch deep enclosure complements the latest flat panel televisions and also makes the L820 the perfect surround channel solution.
