In search of DC lv 4 12s box design

[JNells]

Looking for a design for 2 dc level 4 12s.

front forward facing subs, center ported (either slot port or 4-6" aero) sealed off from trunk. Would like tuning somewhere between 32-35

Dimensions:

Optimum first, max dimensions second

H x W x D

15 x 36 x 15

16 x 38 x 20

I'm using 3/4 birch ply, and I plan on doing double on the front face where subs are mounted.

Thanks in advance for any input to get me in the right direction

Cheers

So here is a suggestion for your reference, power: to 3K for the pair, amp subsonic filter to 28Hz, minimum port clearance 4 1/2", figure is just an assembly guide:

NOTE: If building outside you need to build a cardboard dummy box to test fit in it's way inside.

Oh wow... Above and beyond my expectations, I really appreciate it, thank you Joe X! You are the man!

Just wanted to thank you again for the design and cut list, thought I'd show how it's turned out... Not 100% finished, will be "beautified" with paint/carpeted, but here it is built and sanded.
