ABSTRACT:
At least one active and one inactive speaker element or radiator are mounted in each of a plurality of differently sized speaker housings, each of which housings has a fundamental resonant frequency different from each of the other housings. An audio signal is applied simultaneously to each of the active radiators, which in turn create in each housing acoustical wave forms which drive the associated inactive speaker.
