Abstract

The invention relates to a speaker enclosure (1) with extended spatial diffusion, which enclosure comprises at least two acoustic transducers which, each having a favoured acoustic emission axis (2A), are oriented in such a way that their favoured emission axes are themselves oriented in different directions (D1 to D4), particularly divergent directions when they are viewed in projection in an angular orientation sector defined in space. It is characterised in that the various transducers with the favoured emission axes (2A) oriented in different directions (D1 to D4) are arranged with their points (7) called "point source base" situated on a line, called base line, which extends in a substantially midplane and is perpendicular to that of the angular sector in question.
