It is important to find out how many loudspeakers are necessary for multichannel sound systems to reproduce the spatial impression of diffuse sound field. This paper discusses this issue in the case when loudspeakers are placed, symmetrically along a concentric circle around the listener, and at the same height of the listener`s ear. It becomes clear that the spatial impression of diffuse sound field can be reproduced by only two symmetrical pairs of loudspeakers (that is, four loudspeakers in all). On this arrangement, one pair of loudspeakers should be place in the frontal area around the listener with an angle of about 60 degrees, and the other pair should be in the rear area with an angle of 120 to 180 degrees.
