do the mtx 8000 12"s sound best in a sealed or a bandpass ported box? there would be 4 ports on the ported version

It'll be louder in ported, but sloppier. I had 3 6000's in a sealed box, sounded purprisingly loud, I suggest you seal it. Give each sub around 1.5-2 cubes.

yea I have a mtx T81244A .... ok... I'm just going to test what my first box sounds like... tell me if my calculations are correct...

calculating total Vol (subtracting driver displacement also) I got 2.74 cubic feet

for the port (obviously not included in the 2.74) i measured... 2 inches x 16.5 inches with a length of 13" ....

does this equal approx 42.5 Hz?

ok it's been a while and those mtx's sound great a little sloppy but loud...but now my friend got two 12"s for free from a friend and we were wondering whether that box would work for those subs as well
