The spatial separation between drivers in a loudspeaker system affects the radiation pattern over the frequency range where more than one driver contributes to the total acoustic output. An analysis of conventional crossover networks shows that the main lobe of the radiation pattern shifts in direction and increases in amplitude. A new network transfer function, which can easily be realized with operational amplifiers, eliminates this problem. Additional active delay networks are used to compensate for offsets in the acoustical planes from which the individual drivers radiate. The audibility of phase distortion is investigated with the conclusion that it is undetectable for the proposed types of networks.
