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 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 Wide Dispersion Surround Technology (WDST) provides crystal-clear sonic detail even in listening areas with less than ideal configurations. The Tractrix Horns deliver a 90-degree wide by 60-degree high dispersion pattern. By aligning two horns at 90-degrees with respect to each other, WDST smoothly covers a 180-degree horizontal arc. In other words, the surround sound is pointed at you no matter where you are seated.While increased baffle ribbing around the horn mouth dramatically improves acoustics across the sonic range, the crossover utilizes Klipsch custom internal wiring and the finest components to provide signal purity and perfect driver in a matte black vinyl finish, the RS-52 also features side-firing ports to eliminate turbulence noise and back-panel keyholes and 1/4" threaded inserts to simplify installation. A low-diffraction, magnetically attached grille further accentuates the elegance of this speaker.
