To put things into perspective look at Dominguez ULF thread.
3 XV15's in a 2400^3 room score 800 @ 16hz which is a 4 star rating, meaning the system is capable of clean reference level output down to 16hz.
2 Submersive HP's in a 8000^3 room score 2570 @ 16hz which is a 2.5 star rating, meaning the system can not reach reference level output below 25hz cleanly.
This is not to boast or brag, more so to show how easy it is to get great output out of lesser subs when the room is small. 3 XV15's are similar in output to a Triax in the 16-30hz range and down a couple db above 40hz. So In a 4000^3 room I would guess a 3 star rating, meaning you will come up short trying to reach reference level output. Bear in mind anything above 1.5 star is more bass then a average person would want or need but this is AVS. Hopefully this puts things into perspective for you. Check the thread out when you get a chance.
Thanks for the info and link... I subscribed to it so I can get back to it when I am ready.
