I performed outdoors many times at an upscale retirement community, and while they had seating outdoors as well for the residents, they could clearly hear be indoors at the adjacent 60 seat nite club of the facility. I performed close to the entrance, which was a large, double door entry, and the outdoor seating was on the adjacent patio where the residents were at least 50 or more feet away. Fortunately, I had the Bose L1 system while reached everyone in the vicinity.

Good luck, Scott,
