1. An audio device comprising:
a housing including an interior;
a first cavity disposed within the interior, the first cavity having a first volume;
a second cavity disposed within the interior, the second cavity having a second volume and acoustically sealed from the first cavity, the second volume being greater than the first volume;
a third cavity disposed within the interior, the third cavity having a third volume and acoustically sealed from the first cavity and the second cavity, the third volume being less than the first volume;
a first loudspeaker coupled to the housing and at least partially disposed in the first cavity, the first loudspeaker oriented to emit first sound towards a first side of the audio device;
a second loudspeaker coupled to the housing and at least partially disposed in the second cavity, the second loudspeaker oriented to emit second sound towards a second side of the audio device, the second side being orthogonal to the first side; and
a third loudspeaker coupled to the housing and at least partially disposed in the third cavity, the third loudspeaker oriented to emit third sound towards a third side of the audio device, the third side being opposite the first side.
 
8. A device comprising:
a housing including an interior surface and an exterior surface, the housing having:
a first cavity of a first size formed at least in part by the interior surface;
a second cavity of a second size, different than the first size, formed at least in part by the interior surface, the second cavity being separate from the first cavity; and
a third cavity of a third size, different than the second size, formed at least in part by the interior surface, the third cavity being separate from the first cavity and the second cavity;
a first loudspeaker coupled to the exterior surface and at least partially disposed within the first cavity, the first loudspeaker oriented to emit first sound outward from the device in a first direction;
a second loudspeaker coupled to the exterior surface and at least partially disposed within the second cavity, the second loudspeaker oriented to emit second sound outward from the device in a second direction that is different from the first direction;
a third loudspeaker coupled to the exterior surface and at least partially disposed within the third cavity, the third loudspeaker oriented to emit third sound outward from the device in a third direction that is different from the second direction; and
a cover disposed over at least a portion of the housing, the cover visually concealing the first loudspeaker, the second loudspeaker, and the third loudspeaker.
 
16. A device comprising:
a first loudspeaker oriented to emit first sound outwards from the device in a first direction;
a second loudspeaker oriented to emit second sound outwards from the device in a second direction that is different from the first direction;
a third loudspeaker oriented to emit third sound outwards from the device in a third direction that is different than the second direction;
a unitary housing having an interior surface, wherein the unitary housing includes:
one or more first sidewalls that extend from the interior surface to at least partially form a first back volume for the first loudspeaker, the first back volume having a first size,
one or more second sidewalls that extend from the interior surface to at least partially form a second back volume for the second loudspeaker separate from the first back volume, the second back volume having a second size different than the first size, and
one or more third sidewalls that extend from the interior surface to at least partially form a third back volume for the third loudspeaker separate from the second back volume, the third back volume having a third size different than the second size; and
a seal coupled to the unitary housing, the seal at least partially enclosing the first back volume, the second back volume, and the third back volume at a first location that is spaced apart from a second location at which the one or more first sidewalls, the one or more second sidewalls, and the one or more third sidewalls extend from the interior surface.
