The New Reference Series 800 Floor Standing Speaker features the most dramatic upgrades since the series' inception, including many technologies derived from the Klipsch Reference Premiere Series. The Spun-copper thermoformed crystalline polymer woofers utilize trickle-down technology from Klipsch's highly acclaimed Reference Premiere series of speakers. The two 8-inch injection-molded graphite woofers provide deep, distortion-free bass, while the exclusive Klipsch 1-inch aluminum LTS tweeter and larger 90 x 90 square Tractrix Horn provides improved coverage, bandwidth and directivity control. Easy to setup, supports Dolby Atmos, and has amazing sound that will blow you away!
