ABSTRACT OF THE DISCLOSURE An electrically driven loudspeaker is coupled to the atmos- phere, which is to carry sound to the human ear, through a hol- low coupler the inlet end of which has a cross sectional area com- parable to the effective area of the loudspeaker, said cross sect- ional area decreasing progressively from said inlet end to an outlet end of substantially smaller cross sectional areas. In a specific embodiment of the invention, an exponential horn is form- ed within the confines of a loudspeaker cabinet enclosure, and the inlet end of the horn is coupled to the electrically driven loudspeaker by means of the hollow coupler also formed within the cabinet enclosure. The outlet end of the coupler has the same cross sectional area and shape as the inlet end of the horn.
