Claim:
1. A loudspeaker system comprising: a linear acoustic source; a waveguide configured to radiate the sound energy from said linear acoustic source, said waveguide having a proximal aperture for receiving the sound energy and a distal aperture for radiating the sound energy, and a surface therebetween for controlling horizontal dispersion of the sound energy emitted therefrom; a first driver and a second driver provided on opposing sides of a central plane bisecting said distal aperture of said waveguide; signal processing circuitry comprising crossover circuitry that is configured to split an input signal into a first signal within a first frequency range and a second signal within a second frequency range, wherein the second frequency range is lower than the first frequency range and overlaps with the first frequency range over an intermediate frequency range residing between the lower −6 dB frequency of the first frequency range and the upper −6 dB frequency of the second frequency range, and wherein said crossover circuitry is in electrical communication with said linear acoustic source and said first driver and said second driver for providing the first signal to said linear acoustic source, and providing the second signal to said first driver and said second driver; wherein said first driver and said second driver are provided with a relative spacing such that acoustic interference between said first driver and said second driver occurs within the intermediate frequency range, such that the acoustic interference is suppressed at least in part within the intermediate frequency range by the sound energy emitted by the waveguide.
