If a speaker "images" in different locations at the same time it most likely has no image at all.
Well I can assure you that is not true. Listen to a pair of Ohm, mbl German Physics or other good quality omni designs. The imaging and soundstage (when set up properly as always) is top notch. I have several pair of Ohms and have owned a pair for 30 years now and can vouch for that. I’ve heard mbl set up optimally as well and that is in a class of its own in regards to 3-d soundstage and imaging from most any location in the room. You do need a very special room for that with those though.
