What I know is that if I place my sub in the front right corner then EQ it to MLP, the back left corner and back wall basically get the inverse frequency response of the front right corner. That is why I wonder if opposite corners would balance things out. Also, opposite midwall placement is not possible.
In a square room you certainly have room gain, but square rooms tend to have a lot more nulls because of equal interactions that cancel each other. Multiple subwoofers in a square room is always going to be better than one, because you can reinforce certain frequencies better with two woofers instead of letting the waves on the sidewalls continue to cancel each other out. I definitely think you'll get better response in your room with a second sub (identical!!!) in that corner.
I don't really get the bit about "inverse frequency response" that you mention. I think you mean that the phase will be 180 degrees in the other direction, leading to timing issues and slow bass? The best way to deal with this is with a corner bass trap to reduce that reflection and allow the other wave to stand out over it in amplitude, which will lower the amount of cancellation you're getting as well. I don't know if my physics lingo is correct, but hey Maybe Dave will chime in.
