just ignore the driver cutouts in the pics, you can do dual 12's in any of them.

yeah, check out kpozr's thread on a box build for ARMY-KILLA (which ended up being scrapped, and a new box for himself).

i came up with this for him:

do the 14" x 42" side facing up with the subs on that panel.

or you can play with this site:

http://www.subwoofertools.com/forum/ported-box.asp?Ew=41&Eh=14&Dia=6&Xmax=15&Vd=.08&NumW=2&Vb=4&Fb=30&Qts=&Vas=&Fs=&CE=0

but it seems to think that with that the proper xmax value (11.5 mm for your drivers) you only need a 2.75" wide port. it might be right, but i'd go with more (4"+ wide), that's why in the link i have entered 15mm xmax, so it makes the port bigger. i guess the link and the pic of the plans i threw together for kpozr are pretty much identical //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif and they both will save you a lot of leg room compared to a 19" depth like you originally mentioned.
