Abstract:
A sound reproduction system for creating a unified sound source field from a plurality of audio signals, comprising:a horn of a loudspeaker enclosure having multiply segmented portions according to the frequency response of the horn, comprising a throat and an aperture extending outwardly from the throat; a loudspeaker driver coupled to the throat of the horn operating in a first one of a plurality of frequency ranges; a pair of loudspeaker drivers operating in a second one of the plurality of frequency ranges, wherein the second one of the plurality of frequency ranges is at a lower frequency than the first one of the plurality of frequency ranges, said pair of loudspeaker drivers being coupled to a respective one of the multiply segmented portions at a distance from the throat of the horn according to the frequency response of the horn for summation of audio signals generated by each of the respective loudspeaker; said loudspeaker drivers being positioned for coupling the plurality of audio signals operating in the plurality of frequency ranges into the aperture of the horn; and wherein respective ones of said pair of loudspeaker drivers are coupled to said respective one of said multiply segmented potions at a distance from said throat corresponding to the distance for said audio signals from the loudspeaker driver to travel Â¼ wavelength.
