An experiment on the subjective performance of virtual image accuracy is reported when a sound source is reproduced by a  2-loudspeaker array. Assessments are made for a range of loudspeaker subtended angle and loudspeaker distance to identify the optimum loudspeaker positions for a given image location, knowledge relevant to designing multi-loudspeaker arrays.  Additionally, the effects on spatial sound reproduction due to different loudspeaker driver configurations and technologies are studied including near-field anomalies.
