The ability to localize a sound in a stereo field or mix is called imaging. Several things will affect the ability of a speaker system to image accurately: How matched the speakers are in construction and level (volume), exactly matched phase, and the interaction of the speakers with the listening environment will all be critical in determining imaging. Assuming that the first items are determined by the speaker manufacturer and your system set up, careful acoustic treatment in your room can often make the largest difference in the clarity, stereo spread, and imaging of your studio monitoring system.
