Actually I don't think I would ever play loud enough to ever do a 1600 watt cab justice even if I was touring nationally on a label. That was just being silly. On the other hand, I like the thought of the EVM in all positions for absolute clarity and no speaker breakup. The EVM in my eyes is one of the most honest speakers you can buy and it reproduces nearly exactly what you put into it. Thus, the idea still stands in my head to run the 200 watters in all four holes of the 4x12. However, I do see the need to flavor it some with C90's at times. It all just depends upon what you are looking for. I certainly wouldn't use that cab with my JMP. My greenback loaded Marshall is all I ever need with that amp aside from some occasional 65's action in my other cab. Personally, I don't think I would ever necessarily need a 4x12 halfback. I think the 2x12 would do just fine. If I needed to be louder I would be mic'd anyway. I kind of like my hearing. Right now I hear enough to know what I don't want to have to.
