I know how to make a single slotted box, but what about a double slotted box. I am looking to put the slots in the middle. I have seen some pics on termpro but I need to know how the formula works.

I wasn't looking for pre-fab. I was looking for a formula for port.

just like using 2 aeroports just calculate the port area on 2 ports combined get your length and cut it in half.

2 areoports is what I have now. I just used the formula from psp. Does it matter if the ports are in the middle instead of on the ends?

I guess it depends on whether your leaving room up the middle or basicly making 2 boxes out of 1 by making the middle of the ports go all the way back. If you dont leave room for the subs to connect behind the ports you basicly are making 2 boxes in 1

I was thinking it may be easier to have seperate chambers, essentially combining two boxes into one. I would rather leave room for the subs to connect.

thats separate chambers.

aka build two identical boxes mirrored to one another and sharing the same top, bottom, and back pieces
