English

A sound source comprising a loudspeaker (6) and a hollow coupler (4) with an open inlet which communicates with and is closed by the loudspeaker (6) and an open outlet, said coupler (4) comprising rigid walls which cannot respond to the sound pressures produced by the loudspeaker (6). According to the invention the loudspeaker (6) comprises a cabinet (8) being narrowed down in the rearward direction. In this manner it is avoided that the cabinet (8) gives a shade from the radiation in the rearward direction, whereby a substantially omnidirectional characteristics is obtained within a relatively large frequency range
