DESC: Adopting a completely new cabinet and driver layout that is similar to the Klipsch THX® Ultra2 KS-525-THX surround speaker, the RS-52 establishes greater output, improved coverage and increased power handling to further extend Klipsch's best-in-class surround sound performance. Exclusive Tractrix® Horns have always been the key component of the Reference Series. In the RS-52, this technology has been refined to include improved throat geometry for a more genuine, lifelike sound. Behind the speaker's dual horns lie 1-inch titanium tweeters with powerful neodymium magnet motor structures to provide a unique combination of precision, clarity and effortless dynamics. The RS-52 employs dual 5.25-inch woofers for a solid bass foundation. These Cerametallic™ woofers with inverted copper dust caps exhibit a very high stiffness-to-mass ratio and superb damping characteristics.
