Abstract:
1. A sound reproduction system comprising a loudspeaker having at least two electroacoustic drivers mounted in the loudspeaker, said electroacoustic drivers in the loudspeaker providing non-parallel directivity to sound fields emanating from the at least two electroacoustic drivers, said electroacoustic drivers positioned in the loudspeaker whereby in plan view the sound field axes cross at a point to cause the sound fields to emanate substantially from said single point in plan view, each sound field having a maximum and a minimum amplitude less than 180° apart with an amplitude gradient there between that is substantially preserved over at least two full octaves, and each sound field being asymmetric about the axis of maximum amplitude of the sound field, at least two channels from an electric signal source, each of said channels associated with the creation of each of said sound fields, said sound fields partially superimposed over an angle symmetrically located between the sound fields' maxima or minima, the amplitude gradient of each sound field versus angle being complementary to the amplitude gradient of the other sound field.
