摘要: An three-way audio system that uses directional arrays for radiating mid-frequency acoustic energy and passive devices to radiate the high frequencies. includes a left channel, right center channel. A crossover network separates channel into low frequency content, midrange content. omnidirectional acoustical device radiates corresponding content of combined first array, comprising signal processing circuitry more than one driver, so is radiated laterally in other directions. device,
