@snapsc - For me, soundstage is one of the most impact parts of stereo playback. If your music sounds like it’s all coming from the same general area then you know it’s not right. If the Impact Monitors are set-up correctly music comes from behind, to the sides, in-between and in-front of them. They basically disappear. You can mess this up by pushing them too close to the front wall, side walls or even too close to each other. I think it’s the unique character of the tweeter array that allows this to happen so well.
