Patent ID: 8553894

Claim:
An audio system comprising: a crossover network for separating a left channel, a right channel, and a center channel into low frequency content, midrange frequency content, and high frequency content; an omnidirectional acoustical device for radiating acoustic energy corresponding to the low frequency content of a combined left channel, right channel, and center channel; a first directional array, comprising signal processing circuitry and more than one acoustic driver, for radiating acoustic energy corresponding to the midrange content of one of the left channel and right channel signal so that more acoustic energy corresponding to the midrange content of one of the left channel signal and the right channel signal is radiated laterally than in other directions; and a first passive directional device, for radiating acoustic energy corresponding to the high frequency content of the one of the left channel and right channel signal so that more acoustic energy corresponding to the high frequency content of the one of the left channel signal and the right channel signal is radiated laterally than in other directions.
