An audio device arranged for being positioned within a room, comprising: a casing rotatable about an axis between a first orientation and a second orientation different from the first orientation, said first and second orientations being relative to a direction of the force of gravity and to a listening position of the room; an orientation input device disposed on the casing to enable determination of an orientation of the casing relative to the direction of the force of gravity; and a plurality of acoustic drivers (191, 192a-e, 193a-e) disposed on the casing, at least a portion of the plurality of acoustic drivers configured to form an acoustic interference array, the plurality of acoustic drivers comprising a first acoustic driver, a direction of maximum acoustic radiation of the first acoustic driver being directed towards the listening position when the casing is in the first orientation, and the direction of maximum acoustic radiation of the first acoustic driver not being directed towards the listening position when the casing is in the second orientation, wherein: in response to the casing being in the first orientation, the first acoustic driver is enabled so that sound is acoustically output by the first acoustic driver when the casing is in the first orientation; and in response to the casing being in the second orientation, the first acoustic driver is disabled, so that sound is not acoustically output by the first acoustic driver when the casing is in the second orientation. a casing rotatable about an axis between a first orientation and a second orientation different from the first orientation, said first and second orientations being relative to a direction of the force of gravity and to a listening position of the room; an orientation input device disposed on the casing to enable determination of an orientation of the casing relative to the direction of the force of gravity; and a plurality of acoustic drivers (191, 192a-e, 193a-e) disposed on the casing, at least a portion of the plurality of acoustic drivers configured to form an acoustic interference array, the plurality of acoustic drivers comprising a first acoustic driver, a direction of maximum acoustic radiation of the first acoustic driver being directed towards the listening position when the casing is in the first orientation, and the direction of maximum acoustic radiation of the first acoustic driver not being directed towards the listening position when the casing is in the second orientation, wherein: in response to the casing being in the first orientation, the first acoustic driver is enabled so that sound is acoustically output by the first acoustic driver when the casing is in the first orientation; and in response to the casing being in the second orientation, the first acoustic driver is disabled, so that sound is not acoustically output by the first acoustic driver when the casing is in the second orientation. in response to the casing being in the first orientation, the first acoustic driver is enabled so that sound is acoustically output by the first acoustic driver when the casing is in the first orientation; and in response to the casing being in the second orientation, the first acoustic driver is disabled, so that sound is not acoustically output by the first acoustic driver when the casing is in the second orientation.
