Maggies are especially good at doing that, but my M22s are also great at throwing a soundstage much wider than they are physically positioned. I often hear sounds coming from beyond the left and right walls in my living room.
Part of that effect is reflections from the walls, but I have a feeling most of it is on the source. If you set up a pair of mics in front of a band, and one of the instruments is far to the left of both mics, then the closer mic will pick up a stronger signal than the further mic.
When you hear that recording played back on a good system, the interplay between the different sound waves from that instrument should recreate its spatial relationship to the other instruments in the band.
