ABSTRACT:
A speaker assembly and its method of operation are described wherein a plurality of drivers are spatially adjustable relative to each other and to a selected critical listening point in order to establish maximum sound coherency for the system. Means for adjustment and calibration of the relative positions of the drivers are provided to facilitate their location upon a mounting sub-assembly, interchange of components within the total speaker assembly, and synchronization of the drivers for one or more desired listening positions within a listening environment. The speaker system preferably includes a low frequency range sub-assembly having one or more drivers supported in fixed relation within the total speaker system, a housing for the low frequency range sub-assembly including selective band-pass energy filtration means for isolating each driver from its enclosure and an internal structure providing increased structural rigidity and reducing non-linear turbulence within the enclosure.
