Claim:
1. An audio device comprising: a casing comprising an array of acoustic drivers, each driver operating in a first frequency range and located along an elongate axis of the casing, the array configured to form a plurality of acoustic interference arrays operating over the first frequency range, each acoustic interference array being associated with one of a plurality of audio channels, the casing positionable between a first orientation and a second orientation different from the first orientation; an orientation input device to detect the orientation of the casing relative to the direction of the force of gravity; a processing device; and a storage accessible by the processing device in which is stored a control routine comprising a sequence of instructions that when executed by the processing device, causes the processing device to: monitor the orientation input device to determine the orientation of the casing; in response to the casing being in the first orientation, operate the acoustic drivers to form a first acoustic interference array by utilizing a plurality of coefficients to configure a plurality of filters; and in response to the casing being in the second orientation, operate the acoustic drivers in a manner different from the first acoustic interference array by changing one or more of the coefficients to re-configure one or more of the filters.
