Claim 17:
18. An arrangement comprising:
an audio playback device comprising a panel; and
a height channel speaker for transmitting sound waves to be reflected off an upper surface of a listening environment, the height channel speaker comprising:
an enclosure having a first side and a second side joined by an inclined surface, wherein the first side has a lower vertical height than the second side;
a transducer installed on the inclined surface and positioned to radiate acoustic energy along a radiant axis that is perpendicular to a plane defined by the inclined surface;
an acoustic reflector attached to the lower side and configured to direct, shape, and focus the radiated acoustic energy to the upper surface of the listening environment,
the second side of the enclosure of the height channel speaker being attached to a back side of the panel wherein at least a portion of the panel forms a barrier that provides acoustic occlusion from the listener facing a front side of the panel such that direct sound transmission from the transducer to the listener is reduced.
