ABSTRACT:
In a speaker system capable of controlling the directivity, a first pair of speaker units are disposed at a cabinet from face having vertical and horizontal axes, so that the diaphragm centers are located along a line which is parallel with the horizontal axis of the front face. A second pair of speaker units are disposed so that the diaphragm centers are located along a line which is parallel with the vertical axis of the front face. The horizontal distance between the centers of the diaphragms of the first pair of speaker units and the vertical distance between the centers of the second pair of speaker units are different from each other. The center of the line which links the diaphragm centers of the first pair of speaker units and the center of the line which links the diaphragm centers of the second pair of speaker units are located at the same position. A fifth speaker unit may be disposed on the front face of the cabinet at a center of an area surrounded by the first and second pair of speaker units.
