Abstract
An acoustic system () for diffusing sound from N channels (Si) comprising audio frequencies, N being greater than or equal to two, the acoustic system comprising a frame (), M loudspeakers (HPj) which are similar to each other and mounted on the frame (), and a processing unit () designed to send M loudspeaker signals (SSj) to the loudspeakers respectively. The loudspeakers are arranged at an angle about an axis (Z), two successive loudspeakers forming an angle (a) substantially equal to 360° divided by M. The processing unit () comprises a splitter () configured to produce the loudspeaker signals (SSj), each loudspeaker signal comprising the same shared bass component (SS) in which audio frequencies that are higher than a first predetermined frequency (f) are non-existent or reduced, at least two of the loudspeaker signals further comprising a specific component (SS) in addition to the shared bass component and in which the audio frequencies below the first frequency are non-existent or reduced, each specific component being obtained from at least one of the channels, and at least two of the specific components being different from each other.
