Why, one front/one back sub, a double distance?

I have two subwoofers, both in an infinite baffle configuration (mounted in the wall, into the outside world or attic space, with,yes, a response flat below 10 htz:;and there is no other way to get this at any price).

One is in the front middle of the room (two long-throw 15"), the other in the back, right hand corner (one 18" very long throw Ficaraudio, and two very capable long-throw 10").

My Onkyo pre/pro calculates the 'distance' of the 'subwoofer' as 24 feet, exactly half of the distance from the listening position from each.

The bass is MUCH better if I override the Onkyo calculation by dividing it in half, the actual distance between the two.

What's the explanation?

Hi Pmcneil, you said "a response flat below 10 htz:;and there is no other way to get this at any price)."

That is a great lowwww bass response, how did you measure this? And I would love to see a graph of it. My sub is flat to 12hz, I use the free program from the Home Theater Shack "REW" with a calibrated mic. What program do you use?
