Decaf Posted August 15, 2009 Report Share Posted August 15, 2009 how can u fit two twelves with only 12" height... u need 13" height, u might be able to get away with 12.5" u should do: 31w*13h*28d 3.96cuft 33.43hz 5" wide port 14.5sqin/cuft of port the piece of wood for the port is 21.5" long so with a max width of 31"... that means 12 for each sub... so 24" + 5" for the port plus 1.5" for both side of the box... that leaves you with 1/2" between each speaker... so put some dowel rod from baffle to back, top to bottom and side to port wall side... i included bracing in the above calulations...
