Because the center channel speaker reproduces more than 60 percent of a movie soundtrack, Klipsch spared no expense when developing the Reference Series RC-52. With its ideal combination of technology, performance and design, this speaker delivers a seamless, engaging soundstage that puts listeners inside the action. Exclusive Tractrix Horns have always been the key component of this critically acclaimed series. In the RC-52, this technology has been refined to include improved throat geometry for a more genuine, lifelike sound. Behind the horn lies a 1-inch titanium tweeter with a powerful neodymium magnet motor structure to provide a unique combination of precision, clarity and effortless dynamics. The RC-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. The RC-52"s rigid cabinet offers improved internal cross-bracing to minimize panel vibrations that can color sound. Twin front-firing ports eliminate turbulence noise, while increased baffle ribbing around the horn mouth dramatically improves acoustics across the sonic range. For signal purity and perfect driver integration, the crossover on the RC-52 features the finest components and Klipsch custom internal wiring.
