A system evaluation measure is introduced to help optimize the loudspeaker arrangement for sound image localization. Directional auditory tests were car-ried out on twelve loudspeaker arrangements. The results show that three of the twelve arrangements yield excellent image localization. Furthermore, it is confirmed that there is a strong correlation between the system evaluation measure and the directional auditory test results.
