OK really good, we have plenty of room to work with Your external measurements need to be 38-inches wide(length) and 16.5 inches tall. Your depth(width) should be around 22-inches. Do not divide the box, let both woofers share the same air space. The port will be 15-inches tall by 3.5 inches wide. It will need to be 16-inches long. You can follow the directions Here You can put the port in the center, if you do shorten the port to 14-inches.
What do you mean, I don't understand. How about a parts list Bottom and Top 21-1/4 by 38-inches Back of Box 15 by 38-inches Side of Box (2) 15 by 20-1/2-inches Port board (1) 15 by 16-inches The baffle board is NOT cut until the rest of the box is put together Baffle Board 16-1/2 by 38-inches Again, use the directions Here
