Joe X Posted January 25, 2012 Report Posted January 25, 2012 If the box is not already physically built then this seems to be around what you want and about right for generic 12"s depending on the power run to them and the drivers themselves Vb should be set higher or lower, it features a double layer baffle: Enclosure Specifications: Fb = 35,015 Hz Vb = 3,962 ft^3 Subwoofer Mounting = Flush Mounted External Height = 15 in External Width = 32,5 in External Depth = 24 in Port Width = 4 1/2 in Cut List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts.

Joe X Posted January 26, 2012 Report Posted January 26, 2012 you think this box would be a good for 2 american bass XFL 12s? Yes, they are recommended for vented enclosures 1.5 to 2.5 cubic feet per sub so 2 cubes per sub is right in the middle.
