Abstract: Electronic crossover audio systems and methods in accordance with the invention provide flat frequency response and the feeling of three-dimensional music reproduction with a well defined image of the placement of various instruments, the vocal source across the sound stage, and a distinct impression of good depth of feel. A four submodule crossover module capable of serially chaining and having a fourth submodule for front and rear center monaural outputs provides infinite segmentation and modification of incoming audio frequency signals as well as provides for center monaural submodules to supply lifelike musical performances with superior clarity in a three-dimensional imaging.
