prob not , I have been in a few situations with those speakers I have played a couple of Gyms it would not be my choice for that larger arena I would use my full system DSR 15 DSR 12 K-8 I have a set of all that is 3000 wt per side but believe it or not those K-8 have pulled there weight in many situations in biger clubs I do a lot of Elk Lodge gigs and I play the Big room with those prob 500-700 seats and they do a great Job there is a thresh hold wall that they will have for the high end so in your case prob not. but I have been very impressed with them and highly recomend them for what they do for the size they are.
