Okay - we are getting waaaaay off topic here, even though it is useful info.
So, from the top:
If we had to start over, what should be done differently? This is obviously a very large room we're working with, and it's not easy to "get it right," so we're going to need the help of the entire collective here. I realize we all do things a little differently, but a unanimous "Hey, do this" would be very helpful. Also, keep in mind that warp isn't willing to experiment with subwoofer placement, unless something has changed in the last two days. The goal is a relatively flat response with enough ULF content to make us all grin from ear to ear. And obviously, output headroom (no clipping) needs to be a priority, and this man likes to listen LOUD!
We already bottomed out a driver during WOTW last week, so that needs to be prevented.
Based on what I've read from you fine folks, I'm certainly in agreement that in this situation independent EQ might not be the best approach; I don't mind EQing all the subs as one. So that's the number one thing I've taken from your comments. Now, what else should be done? And please, dumb it down for us regular folk
