Abstract (en)
[origin: WO8804514A1] A loudspeaker installation has two preferably flat sound guiding surfaces (2, 3) arranged to form a V-shape in front of the loudspeaker (5) or another sound source seen in the direction of the sound radiation, forming an obtuse angle towards each other. The sound radiated is thus better distributed and good room acoustics are obtained. This is particularly the case of a stereo system with at least two loudspeakers (5).
