    Abstract: Loudspeaker system having various loudspeakers (SP.sub.i, i=0, 1, 2, . . . , m) which are arranged in accordance with a predetermined pattern and have associated filters (F.sub.i, i=0, 1, 2, . . . , m), which filters all receive an audio signal (AS) and are equipped to transmit output signals to the respective loudspeakers (SP.sub.i) such that they, during operation, generate a sound pattern of a predetermined form, wherein the loudspeakers (SP.sub.i) have a mutual spacing (l.sub.i), which, insofar as physically possible, substantially corresponds to a logarithmic distribution, wherein the minimum spacing is determined by the physical dimensions of the loudspeakers used.
