ABSTRACT An improved dipole type loudspeaker system has a pair of loudspeakers which are mounted on the front baffle board and the back baffle board of a console and are connected to a signal source so as to be driven in mutually opposite phase relationship. The speakers have substantially the same acoustic characteristics in the medium and high frequency ranges but different acoustic characteristics in the low frequency range. The loudspeaker system produces good surround-sound effect when only a small number are used as rear loudspeakers in, for example, a domestic AV system.
