I understand that. The dimmensions I am giving is interior specs of the box.

So in essense when figuring the port size, that space should be added to the box dimmensions. Meaning that if my box is 5 ft3 and I know that I need 2 ft3 for port, then I need to buid a 7 ft3 box. I am just throwing hypothetical numbers out there, just to make sure that I fully understand.

Box size isn't an issue for me. I can go bigger, but wouldn't that also take it out of the recommended specs for the subs?

I think I want internal port. If this setup isn't going to fit can you help guide me into a setup that will fit.

Here is the quick rundown: 4 Soundqubed HDS300 FS 33.65 hz QMS 6.912 QES .769 QTS .692 VAS .782 Ft3 Outside dimmensions of box: 16.3"x41"x27" = 10.44 all setup in a common chamber Port size: 8"x40"x65.88" @ 30 hz I believe this is all correct but what a double check before I build this box. Thanks
