The Klipsch Reference Premiere RP-600C center channel speaker at RC Willey delivers incredible clarity by leveraging Klipsch’s proprietary Tractrix horn-loaded technology and dual 6.5" copper-spun Cerametallic woofers. Horn Anatomy Klipsch Reference Premiere series speakers feature a compressed molded silicon face that is matted to the 90x90 Tractrix horn to reduces horn resonance for smoother frequency response. Klipsch computer modeled phase plugs acts as a mechanical filter to further ensure a smooth, flat frequency response while protecting the tweeter from damage. All-New Vented Tweeter A vented tweeter design reduces standing waves behind the tweeter diaphragm for a smoother high frequency reproduction. The titanium tweeter diaphragm’s light weight yet rigid composition exceeds the performance of aluminum, polymer or silk tweeters. Klipsch award-winning Linear Travel Suspension technology leverages a piston motion of the titanium diaphragm that lowers distortion and delivers real-to-life sound. A ceramic magnet housing provides premium performance, Klipsch Reference Premiere tweeters set the standard in acoustic reproduction. Cerametallic Woofers Klipsch Proprietary Cerametallic woofers are the RP-600C center channel speaker’s signature statement for both sound and aesthetics. This extremely light, rigid materials holds its shape while being able to deliver lower frequencies with maximum efficiency. 1 Titanium LTS Vented Tweeter with Hybrid Tractrix Horn Dual 6.5" Spun Copper Cerametallic Woofers Bass-Reflex via Rear-Firing Tractrix port Premium Scratch Resistant Ebony Finish Strong, Flexible Removable Magnetic Grille
