The researchers invented the exponential horn, and, on realizing that it needed to be nine feet long to reproduce the lowest frequencies on the new discs, designed a method for "folding" the horn into a cabinet of practical size. The design was released by Victor as the "Orthophonic" Victrola in the autumn of 1925.
Paul Wilbur Klipsch (March 9, 1904 – May 5, 2002) was an American engineer and high fidelity audio pioneer, known for developing a high-efficiency folded horn loudspeaker. Unsatisfied with the sound quality of phonographs and early speaker systems, Klipsch used scientific principles to develop a corner horn speaker that sounded more lifelike ...

The first model was released in 1958, and although no new models are being made (Farkas died in 1992), the series is still being manufactured today. [ 1 ]
The P-series horns have longer bells and a heavier manifold than the M-series. [3] The name of the horn is a P followed by the bells that face forward, followed by R if any are reversed, and then the numbers of the reversed bells; a P12345 is a true five-chime horn with all bells facing forward, while P135R24 has bells 2 and 4 reversed.
