Yes. But you'd still be EQ'ing the 2 subs' interaction too, in addition to individually.

Ok, I see what you're getting at. Only EQ individually, but EQ individually so that the combined response is what you want it. That's another further step forward from what I'm suggesting. smile

Again, it remains to be seen whether doing this prior to equalizing the subs' combined output will confer any advantage (and I won't be doing it for all the reasons mentioned) but if this is indeed your intention, it's quite possible you will come close to accomplishing your goal.

Keep us posted. smile
You get it !! Yes, in the end, I don't know if you could get better performance or not from EQ'ing individually plus the total, vs just EQ'ing the sum total of the response. But theoretically, I like the idea of EQ'ing individually 1st, to give Audyssey smoother profiles to work with when EQ'ing the sum total of their interaction. In effect, it's an attempt to minimize the two subs' interaction before EQ'ing the sum total.
