This si very interesting thread for me, just a couple of points more;

I heard a bass driver can be cut under its resonant frequency, this will allow the driver to go much lower.
Say a huge pro paper woofer with FS at 35 hz: we could use it as ULF channel from 25-30 hz down with open bottom.
I have a pair of nice drivers I will try to run a few tests this week.

Another point; we all know the wonders UHF does, say a tweeter up to 40khz, The few experiments I have done with ULF make me belive the same effect is in order, giving mid range and even highs a better integration and intelligibility to instruments.

I was digging out this old interesting thread:

"A basshorn should pressurize the room and create an environment that allows the MF to be “floated” ATOP of basshorn’s pressuranization. Thy basshorn’s out should act like a high density liquid that would permit the low density liquid (MF and HF) do not sink and to fly freely in a room. However, as soon the LF begin to inflict a listener with own ‘"pulsating room effect" then the value of LF should be minimized"
