b&c 18tbw100-4 . need advice on which boxes to build for these drivers

I have 4 of these drivers and i would like to know which design fits them best .
I only need about 40hz extension .
I usually place a pair of subs left and another pair right. But if the build goes well i might build 2 or 4 more.

I was looking at the mth 46 vs and the mhb4818 and the ms46
I chose these 3 because my mt130s fit well on top of those groundstacked
(Thanks for such a great design by the way)

But if you have another suggestion its also welcomed

You can use this driver in these 3 cabs. The MS-46 will go lower, the MHB-4618, the loudest.
