Ported wall or 4th order wall?

[MrBrownstone]

I have 2 MMATS Dreadnaught !8"s. Ive been contemplating a 4th order wall but have been having some difficulty designing and figuring out all the correct specs required! I know that a ported wall will be easier to design but i don't believe that it will give me the same flexibility of a 4th order! They had been installed in a 6th order but the box started breaking down and i really didn't like the box anyway so it was removed! Any help or advice with this matter would be greatly appreciated! IF any additional information is required please let me know!
