Abstract
A speaker system includes a first array of transducers in a speaker enclosure and, and at least a second array of transducers in the speaker enclosure. The second array is a low-frequency array and the first array is a high-frequency array. The transducers in the first array are configured to have an operating frequency region covering at least the frequency ranges of the first array and the second array, and the transducers in the second are configured to have an operating frequency region covering at least the frequency ranges of the first array and the second array. The speaker system further includes an input port, and a controller operatively coupled with the input port. The controller is configured to provide an electronic-audio signal to the transducers such that the first array and the second array are tuned to different center frequencies and are a two stage dipole beamforming array.
