HORN LOUDSPEAKER ABSTRACT OF THE DISCLOSURE A horn loudspeaker construction wherein an integrated sound chamber and horn assembly is provided by two uniquely configured members that form a highly efficient horn loudspeaker capable of being utilized within a four-inch type electrical box. The horn loudspeaker includes a sound chamber for receiving a magnetic loudspeaker driving assembly and diaphragm. The sound chamber also includes a sound opening having a predetermined acoustic orientation. A first horn stage has a first opening acoustically coupled to the sound opening and is characterized by a flare rate that expands as the first horn stage extends away from the sound opening. The first stage includes an acoustical orientation at the output end that is at least 90° disposed from the acoustical orientation of the sound opening. An output horn stage is acoustically coupled at a first end thereof to the output end of the first horn stage and is provided with a flare rate that expands as the output horn stage extends away from the first stage to define a horn output. The output stage is particularly characterized by the acoustical orientation being varied as the flare rate expands so that the acoustical orientation at the horn output is at least 90° disposed from the acoustical orientation formed by the acoustic coupling of the first horn stage and the output horn stage. -1-
