"Now in its fifth generation, the Reference II Series speakers present even higher sound quality due to re-engineered drivers and a new crossover system. Complete with proprietary Tractrix® Horn technology, each speaker offers the precision, clarity and effortless power for which Klipsch is known. The new line also exudes elegance with several cosmetic upgrades, including new black metallic finished baffles, machined Cerametallic™ woofers, logos and feet.
...
All of the Reference II Series loudspeakers feature lightweight, rigid Cerametallic woofer cones to ensure tight musical bass response. New Tractrix horn tweeters incorporate Linear Travel Suspension and titanium compression drivers, which work together to reduce distortion and provide an open, natural sound. Available in black ash or cherry furniture-grade wood and vinyl veneers, each of these speakers boasts a stylish finish for seamless integration into any décor."
