Abstract
The invention is a method of creating an enlarged listening sweet spot for multiloudspeaker audio reproduction. The method employs a plurality of audio drivers displaced generally in a horizontal dimension for a vertically oriented head of a listener, the drivers operating over a plurality of different passbands. Higher frequency drivers are located closer to one another and displaced more towards a center line of the listening space than lower frequency drivers, thereby causing a smaller change in acoustic ear signals for listeners seated away from the designed-for listening position, but without causing increased low frequency signal capacity requirements for phantom images generally outside the array. Specially adapted signal processing accounting for the layout of the various drivers and their associated crossover networks is employed to create desired audio images.
