Default Rf-7

The RF-7 utilizes a combination of professional grade materials and advanced horn technology for a smooth response and consistent coverage pattern. The Reference Series flagship's 1.75" titanium dome compression driver is coupled to an 8" square Tractrix Horn and powered by an unusually large, video-shielded 22oz. magnet. This combination offers the speed and accuracy needed to deliver clear, accurate, non-fatiguing high frequencies and upper midrange frequencies at any volume level. This design approach is so efficient that it virtually eliminates the most common cause of driver failure Ô?" excessive energy.

The two 10" Cerametallic woofer cones are lighter, stronger and better damped than commonly used cone materials. Cerametallic is a specially treated aluminum that has been anodized, or electro-chemically transformed into ceramic on both outer surfaces. Similar to the motor of the large compression driver, powerful, video-shielded 50oz. magnets drive these woofers, allowing for precise signal tracking without blurring the sound. Aesthetically, the unmistakable copper color of our Cerametallic cones gives the RF-7 its distinctive Klipsch Reference look.
