Bruce, I'm not sure I agree fully with this statement. If the response at the listening position is the same wherever you put the sub, then I agree. But, if the potential sub locations vary in the response they provide at the listening position, then there's an opportunity to have the two subs complement each other. I was able to do that. The result wasn't magical, but I did pretty much eliminate one peak and one dip and pick up a few db below 30 Hz from the combination. And, as you or others have mentioned, I got some headroom that allowed the low end to be EQ'd with less risk of exceeding Xmax (using Audyssey in my case).
It wasn't clear to me how Trekari put his sub in the listening position. I would think it would need to be upside down (it's down firing) and sitting on something to put the sound power out about where the head is positioned. Was that the case? Sitting lower, the sofa/chair would soak up some SPL and change the pattern.
