Center slot port help!

[vnisme 10+ year member]

So I came up with this for 2 15's. If I wanted to make this a center slot port, could I simply just move the port over? Most port calculations for 8 inches wide and 15.5 inches high give me a length in the 20's. My question is that since my box is about 30 inches, would it be correct if I just had a straight slot port in the center? instead of having 2 L shaped ports coming together as I see often. My box has to be long because the height is restricted to 17 and width is restricted to 38. I am concerned about the 2 subs loading differently in a side slot port configuration.

#1 . Use a much better program like Torres to mock up.

#2 . If you're running a center slot you need to put 2 for common walls unless it has to bend or L at the back wall, then it's 3 common. The port is halved in width at the back if again the port needs a bend.

#3 . It will definitely load better center slot.

Thanks A lot! If I were to build this box with the slot to the side and used this for 2 15's. Would the subwoofer closest to the port possibly load differently than the other? Or would The side slot configuration work?

Don't use that calc. It's junk

Yes it can. The reason I say center slot is twofold, proper loading for each sub and bracing through the center without having to add extra material. I build all dual enclosures this way with subs and port on the same plane. Now if you're going with sub up, port back then a side slot is fine.
