Sound reproduction employing unity summation aperture loudspeakers

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 plurality of throat ports for receiving the loudspeaker drivers upon a surface of the horn;
• a first 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 first 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, wherein said first pair of loudspeaker drivers are coupled acoustically to the horn of the loudspeaker enclosure using the throat ports along an outer surface thereof;
• a second pair of loudspeaker drivers coupled to another respective one of the multiply segmented portions of the horn of the loudspeaker enclosure and positioned outwardly and away from the throat operating in a third one of the plurality of frequency range, wherein the third one of the plurality of frequency ranges is at a lower frequency than the first one and the second one of the plurality of frequency ranges, said loudspeaker driver, said first pair of loudspeaker drivers, and said second pair of loudspeaker drivers being acoustically coupled to the horn of the loudspeaker enclosure at respective distances from the throat of the horn for providing a unity summation of an audio sound field at the aperture of the horn;
• said first and second pairs of loudspeaker drivers being positioned for coupling the plurality of audio signals operating in the plurality of frequency ranges into the aperture of the horn.

A sound reproduction method for providing a unified sound source field from a plurality of signals, comprising:

• multiply segmenting a loudspeaker enclosure into various portions of a horn according to the frequency response of the horn with a horn throat and an aperture extending outwardly from the horn throat;
• opening a flare of the horn of the loudspeaker enclosure to provide acoustic coupling in predetermined audio frequency ranges;
• coupling pairs of loudspeaker drivers providing audio signals to respective ones of the various portions of the horn of the loudspeaker enclosure in accordance with the frequency response of the horn;
• and
• operating the acoustically coupled loudspeakers on the loudspeaker enclosure according to the respective frequency response for summation of the audio signals generated by each of the respective loudspeaker sources wherein respective ones of said pair of loudspeaker drivers are coupled to said respective one of said multiply segmented portions at a distance from said throat corresponding to the distance for said audio signals from the loudspeaker driver to travel ¼ wavelength.
