Abstract:
1. A horn loudspeaker, comprising: an acoustic horn, comprising side walls, for determining a horizontal dispersion angle of the acoustic horn, and top and bottom walls, for determining a vertical dispersion angle of the acoustic horn; a plurality of acoustic drivers coupled to the acoustic horn by a diffraction slot having segments, each of the segments separated from adjacent segments by less than one half of a wavelength of a highest frequency of an operational range of the horn loudspeaker; and a circuit for transmitting an audio signal to the plurality of acoustic drivers, the circuit comprising a first signal attenuator electrically coupling an audio signal input element and a first acoustic driver of the plurality of acoustic drivers, and a second signal attenuator electrically coupling the audio signal input element and a second acoustic driver of the plurality of acoustic drivers, wherein the first acoustic driver is directed to a first listening location, and the second acoustic driver is directed to a second listening location, the second listening location being closer to the plurality of acoustic drivers than the first listening location, and wherein the first signal attenuator applies a first attenuation to the audio signal input element, and the second signal attenuator applies a second attenuation, greater than the first attenuation, to the audio signal input element.
