I'm guessing, but 8ish cubes seems good. Don't take this to heart because I've only fooled around with SE's in HT applications.

12 cubes(3 per sub after port and sub displacement) tuned to 30hz
should do nicely

or put them in a 4th order bandpass...they r real beast in that type of box

This is 80's life:

"My son!! He just got married!"
"Bandpass? What?"

"OH NO! We're going to crash into the ocean!"
"OH ****! Is this plane 4th order?"

its a sealed box playig into a ported box
with your situation i would do 6 cubes in a common sealed playing into 5 cubes common ported...yes the box is bigger than a ported box but the output with a given frequecy range will be crazy loud
