What is stereo imaging? One way to explain it – the ability of your speakers and system to create a seamless soundstage as opposed to sound that’s coming from two boxes in front of you. With precise stereo imaging, the two speaker boxes should disappear acoustically, and instead, the notes coming from a drummer, guitarist, vocalist or other musician should appear between, to the sides of, in front of, behind and all around where the speakers are set up, like the sounds are coming from specific points in space.
