Here's my concerns with your scenario my friend. Using a pro amp and mixer, stating that you want to play it loud...in an outdoor environment is an equation for blown tweeters in those M30's. Turning the volume up will overdrive those M30's lickety split with that gear.
Maybe a better approach for you, given the gear you have, and how loud you like it, would be to find some pro speakers which are ment to handle the volume and power and would better match up with the rest of your gear. Just saying is all, hate to see another post from you about your M30's crapping out on ya.
