Here is my graph of the corners measurement...

Is that with both subs in the two corners? That’s some pretty weird-looking response. Almost looks like some kind of comb filter happening. Have you tried taking a reading of each separately. It would help for comparison’s sake. As brucek eloquently put it in a recent thread, the only real reason to separate subs would be to achieve a combined response that you can’t get from each separately.
