single chamber

ok cool so ill stick to 30hz... so the box with port on left and subs on right is ok to build? i kinda wanted to have the port in the middle and subs on each side but cant figue it out.

You can do the center, just make sure you add the numbers up and that the total port length is what you calculated for the tubing you wanted. So make sure your opening is 3.5 inches obviously, and that each port side is 9.5 and 9.5 instead of one big long piece that is 19".

ok gotcha thats how i pictured it in my head that i would have to split the 19" in half for each side but wasnt sure if it would change the tuning... Thanks a bunch man really appreciate it!!

if you are splitting the port down the middle, the middle should be bigger than where it does into each chamber. I'm not sure of the math however.

it will be a single chamber box so there wont be a piece of mdf splitting the port down the middle

i know, the port splits, not the box. 1/2 of the port goes one way and the other 1/2 goes the other way. However, you have the port having the same port area the whole time. I'm guessing each split of the port needs to be 1.75" rather than 3.5" but I don't know the math that well.

yeah idk lol

does no one ever check these pictures to make sure its right?

if you have the port on either side of the box, you need to put in the number 3 for # of common port walls. if the port is in the middle, do 2. this tells the calc how many sides of the box is touching the port.
