Omnidirectional acoustic enclosure whose loudspeakers 3 and 4, outputting the middle and treble frequencies, whose known axes are placed vertically, are loaded by the axisymmetric horns 1 and 2 which, in a vertical diametral section, exhibit two mouthpieces which are symmetric with respect to the vertical axis, when drawn as a conic, and the throat 11 spreading over the whole of the periphery, its middle plane being horizontal. The device which is the subject of the invention can be used to obtain uniform stereophonic output reconstructing the spatial effect of the recorded orchestra, both in width and depth. <IMAGE>
