I have Proac Hexa fronts and was dissatisfied with 2005.2 Eggs as surround backs + rears (4 on the back wall, well behind the listening position; I dont want to hang anything on the side walls): they seemed to create a separate sound stage from the fronts, even after YPAO equalization. I attributed this to their directionality and am testing bipole Mission m3ds surround backs. These seem much better in that they don't seem to create a separate soundfield. They sound very diffuse and laid back (as some reviews suggested they would). Interestingly, the YPAO equalisation is much flatter than with the Eggs, which required a significant taming of the upper frequencies, presumably partly because I have large flat reflective walls. I have considered other rear surround options: - more Hexas: expensive, and even more directional than the Eggs - M&K speakers: 4Ohm and described in various reviews as harsh / unrefined, which is what I want to avoid. It seems as if bipoles are the way to travel. Before I say snap to the Missions, are there other options that might have a little more punch without losing the unified sound field? How are the various Jamos, for example?
