Integral active speaker system which can be configured to be used alone or in pairs, with enhancement of the stereo image

摘要

The system has separators adapted to receive left and right side components of a composite stereo signal. Sequence switches are adapted to distribute signals including one of right and left side components between combinations of central and lateral paths according to a preset distribution. The switches include filters to modify a directivity diagram restored on each lateral path to create a cancellation direction. The filters perform filtration while receiving one of the components based on pressure gradient. An enclosure (10) is presented outside in the form of a widened column.
