AB  - Wave Field Synthesis allows the reproduction of arbitrary wave fields in a large listening area. The theoretical driving function for the loudspeakers states, that a correction filter must be implemented to get a flat frequency response of the system. Practical implementations require an adaptation of the filter to the current source position. In this paper measurements of frequency responses for different source positions are compared. Based on those measurements a method for a proper equalization of the system is proposed. Finally, results of listening tests are shown, which compare the quality of a position dependent filtering with a position independent filtering.
