I just got home from "Riverfest" where, believe it or not, saw REO Speedwagon in concert. (they are still alive!) Anyway, they can still rock!
So I was standing there thinking... What are used for speakers and POWER for these large outdoor concerts? That's a lot of air to be moving. Do they use giant arrays of woofers to get all that bass? hundreds of thousands of watts?
Anybody have experience with concert sound? Seems like it would be challange to get right.
