The RB-15 delivers superb sound through a 5.25-inch woofer and 1-inch titanium-dome tweeter that features a high-energy, video-shielded Neodymium magnet. The tweeter is coupled to an exclusive Klipsch square Tractrix Horn. This advanced horn increases sensitivity while minimizing the room interactions that blur the sonic detail and imaging of conventional speakers. The woofer on the RB-15 is an enhanced version of Klipschs unique, copper-colored Cerametallic material that is stronger than ever. This cone is made of an anodized aluminum that makes it tough but does not detract from its beauty. The anodizing process converts its inner and outer surface to ceramic. The outcome is a rigid cone with outstanding damping characteristics that will not flex or resonate at frequencies within the woofers operating range. Driving this cone is a large, video-shielded magnet and high-temperature, long-excursion voice coil, for high efficiency and deep, powerful, articulate bass without breakup or distortion. Sounds beautiful. To deliver this product properly, it is carefully packed in very strong boxes, thereby wrapped in bubble wrap with lots of padding.
