ABSTRACT:
A speaker system of the present invention comprises a cabinet, at least one speaker unit attached to the cabinet, and a plurality of passive radiators attached to the cabinet and each including a diaphragm and a supporting system supporting the diaphragm. The speaker system of the present invention is configured so that distortion components of sound pressures radiated from the supporting systems of the plurality of passive radiators are canceled with each other, and sounds radiated by the plurality of passive radiators are radiated in substantially the same direction from the cabinet.
