Sparky...Sounds like you get good results on outside events with your Maui 11's... I'll be doing a Event April 6 in a Church Multipurpose room... About 60 feet wide 90 feet long...It's set up with the small stage in the middle of the long wall sending sound across the 60' distance...Floor carpet and walls app 8' high carpet...It has a pitched ceiling long length ways... with some sound baffles installed...it can seat 200 people easily...Purchased the Maui 11G2's from Frank at Audioworks CT...Thank both and Don for Your Helpful Information
