In one embodiment, a loudspeaker includes a housing structure having multiple faces. A first face and second face of the housing are between first and second ends to arrange speaker configurations. The housing structure is configured to rotate to direct at least one of the first speaker configuration and the second speaker configuration for output of audio. In one embodiment, the housing structure is an elongated triangular structure. Loudspeaker configurations can include one or more elements to rotate the housing structure to direct at least one of the first speaker configuration and the second speaker configuration for output of audio. Loudspeaker configurations may also include a controller to operate at least one of the first speaker configuration and the second speaker configuration for output of audio based on position of the housing structure. ## Claims ### Claim 1 A loudspeaker, comprising: a housing structure having a first face and a second face, wherein the first face and second face of the housing are between a first and second end; a first speaker configuration arranged on the first face; and a second speaker configuration arranged on the second face, a motor configured to rotate the housing structure, including rotating both the first speaker configuration and the second speaker configuration together, to direct at least one of the first speaker configuration and the second speaker configuration for output of audio, wherein the housing structure is configured to rotate to direct at least one of the first speaker configuration and the second speaker configuration for output of audio; and a controller to rotate the housing structure via the motor, and further configured to operate at least one of the first speaker configuration and the second speaker configuration for output of audio based on position of the housing structure, wherein when rotated in a first position with the first speaker configuration facing in a first direction, the controller is configured to select the first speaker configuration to be a primary source of audio output, and when rotated in a second position with the second speaker configuration facing the first direction, the controller is configured to select the second speaker configuration to be the primary source of audio output. ### Claim 2 (depends on 1) The loudspeaker of claim 1, wherein the housing structure is an elongated housing assembly having at least one of a triangular, square, rectangular and multi-sided cross sectional profile. ### Claim 3 (depends on 1) The loudspeaker of claim 1, wherein the first speaker configuration and the second speaker configuration each include a plurality of speakers, and wherein the first speaker configuration includes at least one of a different number of speakers, different speaker placement, and different speaker type in comparison to the second speaker configuration. ### Claim 4 (depends on 1) The loudspeaker of claim 1, wherein the housing structure rotates relative to the first and second ends, wherein the first face is angled with respect to the second face. ### Claim 5 (depends on 1) The loudspeaker of claim 1, wherein the housing structure rotates with the first and second ends. ### Claim 6 (depends on 1) The loudspeaker of claim 1, wherein the housing structure is rotatably mounted to the first and second ends. ### Claim 7 (depends on 1) The loudspeaker of claim 1, further comprising at least one bracket mounted to the first and second ends, wherein when in the first position, the controller controls output of the second speaker configuration to enhance or isolate off-axis response and create acoustic isolation. ### Claim 8 (depends on 6) The loudspeaker of claim 6, wherein the bracket is an elongated bar extending along a portion of the housing structure. ### Claim 9 (depends on 6) The loudspeaker of claim 6, wherein the bracket is mounted to at least one of outer surfaces of the first and second ends, support elements of the first and second ends and notched channels of the first and second ends. ### Claim 10 (depends on 2) The loudspeaker of claim 2, wherein when rotated in the first position, the first speaker configuration is the only speaker configuration generating audio output. ### Claim 11 A loudspeaker, comprising: a housing structure having an elongated triangular structure, the housing structure having a first face and a second face; a first speaker configuration arranged on the first face of the housing structure; a second speaker configuration on the second face of the housing structure; at least one element configured to rotate the housing structure to direct at least one of the first speaker configuration and the second speaker configuration for output of audio; and a controller to operate at least one of the first speaker configuration and the second speaker configuration for output of audio based on position of the housing structure, wherein the first speaker configuration and the second speaker configuration each include a plurality of speakers, and wherein the first speaker configuration includes at least one of a different number of speakers, different speaker placement, and different speaker type in comparison to the second speaker configuration, and wherein the controller is further configured to rotate the housing structure via the at least one element, wherein when rotated in a first position with the first speaker configuration facing in a first direction, the controller is configured to select the first speaker configuration to be a primary source of audio output, and when rotated in a second position with the second speaker configuration facing the first direction, the controller is configured to select the second speaker configuration to be the primary source of audio output. ### Claim 12 (depends on 11) The loudspeaker of claim 11, wherein the housing structure rotates relative to first and second end units. ### Claim 13 (depends on 11) The loudspeaker of claim 11, wherein the housing structure rotates with first and second end units. ### Claim 14 (depends on 11) The loudspeaker of claim 11, wherein the housing structure is rotatably mounted to the first and second ends. ### Claim 15 (depends on 11) The loudspeaker of claim 11, further comprising at least one bracket mounted to a first and second end of the housing structure. ### Claim 16 (depends on 15) The loudspeaker of claim 15, wherein the bracket is an elongated bar extending along a portion of the housing structure. ### Claim 17 (depends on 15) The loudspeaker of claim 15, wherein the bracket is mounted to at least one of outer surfaces of the first and second ends, support elements of the first and second ends, and notched channels of the first and second ends. ### Claim 18 (depends on 11) The loudspeaker of claim 11, further comprising a drive unit to rotate the housing structure. ### Claim 19 (depends on 11) The loudspeaker of claim 11, wherein the housing structure is configured to rotate along a central axis of the loudspeaker to position one of the first speaker configuration and the second speaker configuration in a forward facing direction.
