PROBLEM TO BE SOLVED: To produce a speaker system whose stereo feeling is satisfactory even though the system is listened to from any 360 degree direction. SOLUTION: Four or more sets of speaker units are alternately mounted on a circumference with a group of three units including two speaker units emitting left and right sounds or a speaker unit emitting a center sound as one set. In such a case, the speaker units emitting the right sound are mounted with a prescribed angle clockwise and the speaker units emitting the left sound are mounted with a prescribed angle counterclockwise so that the right sound can be heard from a right side and the left sound can be heard from a left side even though the speaker system is listened to from any 360 degree direction.
