I've used this in the past and it will cover any venue up to 1,200 drunken boaters. This was the largest crowd I ever performed in front of, but I also used it for a concert in Aberdeen Municipal Park, which is about 3 acres and had folks dancing at the other end of the park from where I was set up.

Great thing about Bose, you can send it back, no questions asked, with 30 days, for a full refund.

Good luck,

Gary
