1. A device comprising:
- a speaker array comprising three or more speakers configured to produce stereo sound based on left and right stereo signal channels L and R, respectively;
logic to derive a low frequency bass signal, B from L and R;
logic to increase a level of signal B and decrease a level of L or R output by a first speaker of the speaker array as the first speaker is rotated through 90 degrees by way of a rotation of the device between a first and second orientations, and to increase a level of L or R and decrease a level of B output by at least a second speaker of the speaker array throughout the rotation.

Abstract
Left and right stereo channels L and R are provided to a first set of two or more speakers of a speaker array. A bass signal B is applied to a second set of one or more speakers of the speaker array. The level of L and R applied to the first set of speakers is increased as the first set of speakers is rotated to become more horizontally aligned. The level of B applied to the first set of speakers is decreased as the first set of speakers is rotated to become more horizontally aligned.

11. An audio circuit, comprising:
-
stereo left and right channel inputs L and R, respectively; at least three amplifier outputs; and logic to adjust one or more of the amplifier outputs from primarily full range outputs to primarily bass outputs and vice versa according to a parameter representing a degree of rotation of at least three speakers. - View Dependent Claims (12, 13, 14)

15. A process comprising:
-
providing left and right stereo channels L and R, respectively to a first set of two or more speakers of a speaker array, the speaker array configured to provide stereo sound using L and R; applying a bass signal B to a second set of one or more speakers of the speaker array; and continuously decreasing the level of L or R applied to at least one speaker of the first set of speakers as the first set of speakers is rotated through 90 degrees; and continuously increasing the level of B applied to the at least one speaker of the first set of speakers as the first set of speakers is rotated through the 90 degrees. - View Dependent Claims (16, 17, 18, 19, 20, 21)
