Magnepan MC1 & MC3 on-wall speakers

Actually, Riley posted this thread in the HT category. I have similar concern and thought I should posted it up here due to the lack of response in the HT catergory.

"I'm fairly happy w/ my setup, which is 5.2 and all speakers are on the wall. However, I am always on the look for improvement. Thus, I am quite curious about such setup regarding the MC1 & MC3 hang on the wall. I listen to concert DVDs and HT prettery loud. Can the MG handle such loudness given the amp is not an issue? If such is the case, what is the setting for speaker size (large or small) on most pre/pro? If I were to set to loud, could I blow the ribbon, or would the ribbon just rattle? I guess that I want to know how far I can push the MG to the limit. What is the recommended crossover for these babies. I know there is a 30-day trial period, but I'm not ready to go down that route yet. Sorry Riley for sort of stealing your post, but these info maby helpful to us both. Any advised on these MG is greatly appreciated."
