Our gymnasium just got revamped, they knocked down a wall and made it probably about 2.5x as long as it was, and now are calling it a field house. It's still under construction, won't be done until August. I was just walking around with the electrician the other day though and noticed that inside of there, they installed all of the speakers so they are mounted directly on the I-Beam and pointed straight at what will be a wood floor, and there's nothing in there aimed at where the bleachers will be at all. Is it just me, or does this sound like a really bad idea? In addition, can anybody provide me with a diagram or article to explain the physics of this? I thought I had some system design manuals sitting around that explained this but I've been unable to find any. I want something that's easy to take to the project managers though so that the issue can be addressed appropriately.
