CORNER FOLDED HORN SYSTEMS
Shown in Fig. 5.12 are top and side cross-sectional views of the most enduring horn design—the Klipschorn—invented and patented by Paul W. Klipsch.
The enclosure is a low-frequency horn so folded that it can be placed in the corner of a room to utilise reflections from the floor and walls to improve the impedance match at the mouth of the horn and thereby increase response at low-frequencies. It is as though the walls and floor act as extensions of the horn itself.
A horn of this design offers efficiency that can be 10 to 50 times as great as that offered by an infinite-baffle design ; and therefore, a given amount of acoustic power can be generated with much less excursion of the speaker cone. This often significantly ...
