Abstract:
A loudspeaker system for receiving an electrical signal and transmitting an acoustical signal, said acoustical signal being directional and having a substantially continuous beamwidth across a plurality of frequency transitions, comprising:a horn-loaded, middle frequency transducer for producing a middle frequency portion of said acoustical signal, said middle frequency transducer directing said acoustical signal into a horn assembly having at least two opposing interior surfaces and an output aperture, said middle frequency transducer and said horn assembly having a common central axis; and,a direct radiating, low frequency driver for producing a low frequency portion of said acoustical signal, including a first low frequency transducer having a first voice coil and a second low frequency transducer having a second voice coil, wherein a distance D1 measured from said first voice coil to said second voice coil is related to a second distance D2 measured across said output aperture.
