ABSTRACT:
A multiple-driver, single horn loudspeaker is disclosed. The loudspeaker comprises an enclosure having a centerline and a single horn mounted therein. The horn has a throat located in the enclosure, and a mouth which is located at an open end of the enclosure. At least one high frequency driver is used to produce high frequency sound which is directed through a passage located along the centerline and are coupled to the throat of the horn. Low frequency drivers for producing low frequency sounds are either located on either side of the centerline and are also coupled to the throat of the horn, or a single low frequency driver is located along the centerline and connected to the throat of the horn. The single horn acts as a waveguide for the sound produced by both the low and high frequency drivers.
