The ES80 floorstanding speaker delivers accurate performance – with dramatically reduced distortion for incredibly realistic sound – thanks to its PolyPlas™ woofers and midrange driver, and its titanium-laminate tweeter. The dual 6" woofers deliver deep, accurate bass response, and the ultrahigh-frequency driver extends response out to 40kHz, making the ES80 perfect for the latest high-definition recordings and broadcasts. The tweeter is mounted in our proprietary Elliptical Oblate Spheroidal™ (EOS) waveguide for improved high-frequency dispersion anywhere in the listening room.
