Abstract
An audio device incorporates first acoustic driver at least partially overlain by a first acoustic reflector to define a first effective direction of maximum acoustic radiation and a second acoustic driver at least partially overlain by a second acoustic reflector to define a second effective direction of maximum acoustic radiation, wherein when the audio device is positioned in a room such that the direction of maximum acoustic radiation of the first acoustic driver is substantially perpendicular to the direction of the force of gravity, the first effective direction of maximum acoustic radiation is bent more towards a listening position at which a listener is expected to be located than the first direction of maximum acoustic radiation and away from a floor, and the second effective direction of maximum acoustic radiation is bent more towards the listening position than the second direction of maximum acoustic radiation and away from a wall.
