Box Design... please help

[AK SloPok 10+ year member]

I am racking my brain (not that hard to do). Trying to come up with a workable ported box for 4 9kv.2 drivers. The box would be easy but my problem is I have limited exterior dimentions that are not square.

The exterior dimentions I am working with is 56 long, 12" high, 8.5"deep bottom and 6.5" deep top.

Is this even possible? I would like for the tuning to be below 35hz, maybe fewer drivers? They displace .02cuft each...

I've been playing with it and seems to be very possible as long as the subs aren't too deep (didn't feel like looking up the specs)

I just realized how stupid I have become...

ED suggests .5 cu ft for each driver ported smallest being .3 cu ft, 4 drivers may be too much.

I will play with that one, thanks for the tip.
