Four Laws of the Klipsch Universe
Beginning in 1946, company founder, Paul W. Klipsch believed four principles to be the foundation for great sound. Together, these four design principles—high efficiency with low distortion, controlled directivity, flat frequency response, and wide dynamic range—have and always will be the foundation for our stunningly powerful and precise sound.
Every Reference speaker utilizes our Tractrix® Horn technology for lifelike sound, more output using less energy, improved reliability, reduced distortion and a large soundstage with well-defined imaging
Our light, yet rigid Cerametallic woofer cones feature specially treated aluminum to help better dampen and prevent distortion.
Titanium tweeter with linear travel suspension—trickle-down technology from our flagship Palladium Series—provides an open, natural sound, making you feel as if you’re in the studio with the recording artist or on the set of a film.
Enhanced crossover frequencies offer smoother on-axis and off-axis integration.
