In this article,a method to design two way loudspeaker crossover networks by genetic algorithms is described. The measured sound pressure frequency response and the impedance frequency response of the woofer and the tweeter are used to simulate the response of the system when the loudspeakers are connected to crossover. The component values of the crossover are selected by genetic algorithms such that some responses are optimun. A design example shows that the calculated and measured frequency response are accordant.
