The proposed invention is an acoustic enclosure consisting of a loudspeaker A and of an open housing of parallelepipedal or other shape; the internal dimensions H, L, P of the housing are calculated so that they are equal, either to the wavelength lambda 0 of the resonant frequency Fo of the loudspeaker A, or to a multiple of the wavlength lambda o of the resonant frequency Fo of the loudspeaker A, or to a sub-multiple of the wavelength lambda o of the resonant frequency Fo of the loudspeaker A. 1) - The enclosure can consist of several loudspeakers and several open housings, whilst conforming with the same principles of construction. <IMAGE>
