Product Description:
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! 

• Handles up to 600W peak power (150W continuous)
  For robust and controlled audio that is crisp and clear.
• Two 8" spun-copper TCP Woofers
  Utlizing trickle-down technology from Klipsch's Reference Premiere series, the TCP woofers have steeper angling of the cones for a smoother response and improved accuracy and transparency.
• 2-way speaker system
  Sounds like 1 source rather than several separate sources.
• MDF Cabinetnt with scratch-resistant, textured wood grain vinyl
  Stylish aesthetic with absolute durability that results in a seamless integration into any décor.
• Sleek, modern appearance
  Hidden fasteners, edge-to-edge horn, and low-profile magnetic grilles give the speakers a polished, modern appearance.
• Rear Tractrix Port
  The rear Tractrix port is perfectly matched to the cabinet and woofers, creating ideal airflow with mininimal distortion or turbulence even at the lowest frequencies.
• High Quality Cabinet Design
  Reinforced 3/4" MDF construction with an all-new bracing design reduces cabinet vibration for less audible coloration and improved sonic accuracy.
• Refined Atmos Connections
  Upgrading to Dolby Atmos is extremely easy with the simple and hidden connections located on the back of the speakers. These refined connections reduce the amount of wire seen and hold them in place for better wire management.

  Ensures a wide range of accurately reproduced sound.
• 98 dB sensitivity
  Ensures crisp, robust audio.
• 8 ohms nominal impedance
  Ensures efficient conduction of power through the speaker.
