Abstract
A first array of speaker elements is disposed in a cylindrical configuration about an axis and configured to play back audio at a first range of frequencies. A second array of speaker elements is disposed in a cylindrical configuration about the axis and configured to play back audio at a second range of frequencies. A digital signal processor generates a first plurality of output channels from an input channel for the first frequencies, applies the output channels to the first array of speaker elements using a first rotation matrix to generate a first beam of audio content at a target angle about the axis, generates a second plurality of output channels from the input channel for the second frequencies, and applies the second output channels to the second array of speaker elements using a second rotation matrix to generate a second beam of audio content at the target angle.
