soundqubed conundrum

I have a @12.5 net cubic foot enclosure built (except for baffle) tuned to 37Hz. I have 4 sdc2.5 15's at my disposal. I built the box with using 3 of the subs in mind. Would I be better off with 4 at 3.125 each or 3 at 4.17 each? Amp is a bc3500.

I would do 3, the SDC's like large enclosures. I normally run the 15's in 4.25 - 4.5cubes each...
