<p>An improved dipole type characteristic loudspeaker system has a pair of loudspeakers (1 and 2) which are mounted on the front baffle board (4) and the back baffle board (5) of a console (3) and are connected to be driven in each-other opposite phase relation and have substantially the same acoustic characteristics in the medium and high frequency range but different acoustic characteristic in low frequency range; such loudspeaker system produces good surround-sound effect when used as back loudspeakers only with small number.</p>
