The front panel was kinda sloppy. Have the thing pretty much pulled apart just trying to tighten it up a bit. I do not know the exact effect of the loading which is why I am posting. I hate cooked drivers but I like to get low. So those Ev drivers were not cutting it. 3.3mm of xmax. It appears more modern subs have double that. I am def not claiming to be a sub master (no pun intended) but twice the xmax has got to push some more air.

The 9 cubic foot box runs out of Xmax 15% before running out of power.
Technically, you will rip the speakers first in a big box and cook them first in a small box, trying to get the LF the small box does not produce
.
It is all a continuum, these three alignments show how each "works", but you can choose things "in between".
Just make sure the box is well braced, try to make the ports closer to square (or triangular) rather than thin slots. And check the tuning to make sure it came out like you want it !
If the old EVM 18s work, I may be interested in them.
I have lots of stuff to trade..
