ABSTRACT

A loudspeaker designed to channel the signal (usually the bass) through a folded path, in order to save cabinet space. While the design may preserve the acoustic characteristics of the straight horn, cross vibrations can occur at the bend points, so the design has to be worked out carefully. The most notable folded-horn design was worked out by Paul Klipsch in the late 1940s, and it made use of the room’s corner to extend the length and enlarge the cross-section of the horn mouth.
