....... large main room which I am in the center of...

i need clarification, it's important. do you mean "center", as in your mixing position being half-way between the front and rear walls (and assuming you are firing your speakers down the longest length of the room)?

The room is essentially a large square. It is the basement of the house, and i am near the center of the room, as the basement is filled with stuff collected from years of doing theater. And by large square, I would say approximately a 35' X35' concrete and cinder block basement with no acoustical treatment. . . i mean, I don't see any issues there. . . at all. . . sarcasm. . .
