Abstract
An array of speaker modules includes a first speaker module having at least one electroacoustic driver and a housing that together define a first acoustic cavity having a first cavity volume. The array also includes a second speaker module having at least one electroacoustic driver and a housing that together define a first enclosed volume that is greater than the first cavity volume by a first volume difference. The second speaker module includes a first internal enclosure having a first internal volume that is substantially equal to the first volume difference. The portion of the first enclosed volume that is outside the first internal volume defines a second acoustic cavity having a second cavity volume that is substantially equal to the first cavity volume. This configuration enables the performance of low frequency acoustic drivers in the speaker modules to be substantially matched without requiring complicated alternative approaches for matched performance.
