ABSTRACT:
In a sound reproduction system having two loudspeakers located in front of a listener, an input audio signal is divided into a plurality of channel signals which are respectively applied through voltage adjusting devices to the front loudspeakers and also to additional speakers or localization networks to generate additional real or phantom sound sources at .+-.90 degrees to the normal to the listener. The additional sound sources and the front loudspeakers are located symmetrically with respect to the listener. By manual operation of the adjusting devices a sonic image can be localized at any point in the front half plane. Continual operation of the adjusting devices causes the localized sonic image to be moved continuously within the localizable area.
