Stereo imaging is the illusion created of a spread of sound between the two speakers that mimics the sound heard at the original performance, or that is created in the studio. It typically has parameters that include perceived width, height, depth, specificity and instrumental separation. Some systems and technologies can give a better image than others (our concentric drivers for instance), and some listeners judge this parameter less important than the musical performance itself, such as perceived rhythm and timing, musical communication etc.
