The Klipschorn is the proprietary loudspeaker invented by Paul Wilbur Klipsch in 1946. It is notable for its large enclosure and three-way design with a woofer, squawker, and tweeter, that separately deliver the bass, midrange, and treble portions of a sound signal. The horn structure is compound and folded, to deliver sound accurately across the maximum frequency range.
The Klipschorn has an extremely high-efficiency design, meaning relatively little input power is required to generate a big sound. Klipschorn even use walls to further amplify their sound. Paul Klipsch demonstrated that the Klipschorn was capable of reproducing concert hall dynamics with as little as 1 watt of power.
