Abstract (en)
[origin: WO2015063377A1] The invention relates to a sound system comprising at least one Digital Signal Processor control module, acting on a signal to the high-frequency transducer (1) and on a signal to mid-frequency transducer (4) in such a way as to apply, in a common frequency range, at least one magnitude parameter as well as at least one phase parameter so as to produce a directivity along the same angular sector as a directivity produced by the orientable shutters (6).
