Ok so these appear to be modified w bins to a reflex bin. I have one stripped of the carpet and cleaned up decent. I am thinking of replacing the EV drivers with Lowriders. Although I just missed a deal on ebay for a lot of 4 for 600$ which Im pretty bummed about. So calculating cubic feet the cabinet appears to be. 46"x 22" x 27" / 1728 = 15.8125. Peavey lists the lowrider as 9 cubic feet for a single sub does this mean a dual sub should run 18 cubic feet. Also I am thinking of running a single rectangular vent in the center of the two drivers as I have seen other manufactureres do. Please advise if you feel inclined thanks. Where is Art Welter that guy knows his stuff.

Do you know what the cabinet is tuned to now? Why do you want to change the port, and do you know what effect that will have on the cabinet and the loading of the drivers?

A slightly small cabinet generally means you can't get quite as low. It can also mean the drivers are less likely to get cooked (large box means lots of excursion down low).

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  Laughing .
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..
