I have a set of "gunned" MMGs that are now over ten years old , they show no sign of delamination ( the back side with the mylar and voice coils is exposed). I think the hardwood frames and the upgraded crossovers help overcome a lot of what some complain about with regular maggies. My set is on the short wall of an L shaped basement room, 13' x 22' with another 16' x 20' off to one side (the L). They are about four feet from the reflecting wall and about that far from either side, with the tweeters inside. I do use a sealed sub for the bottom octave (crossed at 50 hz) and there is a sweet spot, but it's not as narrow as my old SMGa's. I will admit they are not ideal for rock & roll, but they shine with piano, acoustic instruments, and female vocals. I have heard ehoove's modded MG III's a few times- if I had more room I would go that way.
