Abstract
The disclosure includes a sound system comprising at least one Digital Signal Processor control module, acting on a signal to the high-frequency transducer and on a signal to a mid-frequency transducer so 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.
