So I am not saying don't go after ULF. But, just make sure everything else is covered first.
Which brings us back to your boxes. I don't know how the 4 sealed will behave in that space but why don't you just find out and do some measurements. Mess around with placement and then decide if you want/need more output.
Personally, I would not hesitate to give up 15Hz and below for earth shattering 15Hz and above.
So, I have the clone amp about 1/2 on the gain nob, and J River at "reference" and I'm totally happy with what I'm getting in room after re-cal with Audyssey on the receiver and a few adjustments in the J River settings.
In fact, sometimes I turn it down.
Now, I haven't yet tested the limits at all and haven't gone for
weird chinese organ drums music or the ULF of some of those demo movies but for great music and very satisfying movie experience in a large room - it is fine.
Just counting down the years until I get after that basement. Tree house and landscaping not to mention garage organizing is going first.
I don't think I'll be modding the 4 UXL-18 boxes at all for now.
