An audio device arranged for being positioned within a room, comprising: a casing, an axis extending along an elongate dimension of the casing, the casing rotatable about the 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; a plurality of acoustic drivers (191, 192a-e, 193a-b) disposed on the casing and operable to form an acoustic interference array, and a first set of one or more infrared sensors (121a,121b) and a second set of one or more infrared sensors (122a,122b), wherein: in response to the casing being determined to be positioned in the first orientation, the first infrared sensor set is enabled so that it is configured to receive infrared signals representing commands from a remote control or another external control device controlling the audio device, and the second infrared sensor set is disabled; and in response to the casing being determined to be positioned in the second orientation, the second infrared sensor set is enabled so that it is configured to receive infrared signals from the remote control or other external control device, and the first infrared sensor set is disabled. a casing, an axis extending along an elongate dimension of the casing, the casing rotatable about the 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; a plurality of acoustic drivers (191, 192a-e, 193a-b) disposed on the casing and operable to form an acoustic interference array, and a first set of one or more infrared sensors (121a,121b) and a second set of one or more infrared sensors (122a,122b), wherein: in response to the casing being determined to be positioned in the first orientation, the first infrared sensor set is enabled so that it is configured to receive infrared signals representing commands from a remote control or another external control device controlling the audio device, and the second infrared sensor set is disabled; and in response to the casing being determined to be positioned in the second orientation, the second infrared sensor set is enabled so that it is configured to receive infrared signals from the remote control or other external control device, and the first infrared sensor set is disabled. in response to the casing being determined to be positioned in the first orientation, the first infrared sensor set is enabled so that it is configured to receive infrared signals representing commands from a remote control or another external control device controlling the audio device, and the second infrared sensor set is disabled; and in response to the casing being determined to be positioned in the second orientation, the second infrared sensor set is enabled so that it is configured to receive infrared signals from the remote control or other external control device, and the first infrared sensor set is disabled.
