Walled off, I'm estimating somewhere between 50 - 58hz. Do you have some extra MDF and a 10" sub laying around? If so, cut 8 pieces the same outside diameter as your 12's. Then cut a piece to seal off the port. Build an enclosure that will fit into the 12" cutout for the 10" sub. Use one of your circle cut pieces for the face of the 10" enclosure. Use the remaining cuts to seal off the wall from the front wave. Mount the enclosure in one of the holes for the 12's. PM me your phone # and I'll explain the rest. My computer is getting angry.
