Acoustic reproduction system with several loudspeakers - uses unique frequency band filtered from full spectrum signal to drive speaker units

摘要

An acoustic reproduction system comprises a group of loudspeakers (3) to (8) each of which is driven by a unique component frequency subrange of the entire acoustic spectrum. A sound signal from a source (10) is applied in parallel to a bank of filters (11) to (16). The filters chop the acoustic spectrum into the individual frequency bands which are applied to the respective speaker element. The groups of speakers are split into subgroups of three each housed in a separate cabinet (1) or (2).
