Abstract
A loudspeaker includes a housing that has a plurality of walls, which together define an acoustic cavity. An electro-acoustic transducer is mounted to a front wall of the housing, and a motion axis of the electro-acoustic transducer is offset from a centroid of the front wall. The loudspeaker is configured to be stacked with an other loudspeaker of identical construction in a first configuration such that the stacked loudspeakers radiate acoustic energy to produce an omnidirectional radiation pattern; and in a second configuration such that the stacked loudspeakers radiate acoustic energy to produce a cardioid radiation pattern. The loudspeaker includes keyed features which do not interlock and thereby inhibit stacking when the loudspeaker is in a first orientation relative to the other loudspeaker, and which interlock to allow stacking when the loudspeaker is in a second orientation relative to the other loudspeaker.
