The sweet spot for stereo imaging spans only a few tens of centimetres
Evidence
The presented analysis is valid only if the loudspeakers are equidistant from the listener and if their angular distance is no larger than about 60◦. These criteria define the best listening area in terms of where the virtual sources are localized between the loudspeakers, which, in practice, is only a few tens of centimetres in the left–right direction. When the listener moves outside this area, the virtual source is localized towards the nearest loudspeaker, which emanates a considerable amount of sound. Such erroneous localization occurs due to the precedence effect. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1889
