Having owned the predecessor to the Bose L1 Mod II, I can assure you that it would be hard to go wrong with the Bose rig. Granted, the cost is more than some of the competition, but there were a couple Have Guitar Will travel guys in the Florida Keys with that rig who were doing big, outdoor jobs and the coverage was absolutely astounding. I'm talking something nearly 2 acres in size and you could hear them equally as well as if you were just a few feet away. And, the overall sound quality was absolutely awesome.

I have not heard the Maui systems used under these conditions, so I cannot comment on them, though they seem to be loved by those performing indoors in mid size venues.

Good luck on whatever you decide upon,

Gary
