How does this box look/ suggestions

[michigancapri92]

ok so im building a new box for my 2 12" t200 subs and was wondering if this looks like an ok box design, the two aero ports will be in the center with subs on each side, and let me know if i need to do anything different with the ports if they are aero ports. thanks

Looks good but make sure you have a way to brace the box a little and you should be good

is that enough port area ?? the only other configuration i came up with for more port area was 5x 2" aeros giving 15sq/inch port and you think i would need bracing for 2 12" t200s ?? using birch if that helps ?

I think two 3" aeros is going to be good. As for bracing, it won't need much. You may be fine. You might consider adding like a couple dowels between the aero ports and the subs on each side because the top and bottom pieces are a little big to not be braced at all. Other than that everything looks perfect

Oh my mistake, you may not have enough port. You may need to go with the 5 2" aero ports or even a center slot port

In fact, you may want to go with three 3" aeros

3 3" aeros is 21.20 in² seems high and i cant get the tuning down to what i want without going external ports :-/ and you think i will need bracing going up and down connecting the top and bottom or baffle and back ??

i was thinking 5 2" aeros giving me 15in/sq ports

I cannot see how the design because I'm on mobile. How much port area do you have?

He's got 3 cubes with two 3" aeros (14sq.in) at 32hz. Port area needs to be at least 25sq in. or so

[michigancapri92]

i have 14.13 in/sq port 3.02ft/sq volume after woofer/port displacement sunded to 32.29hz box is 14"tall 14.75 inch deep 37.25 wide with double baffle

ive been told 14-17 in/sq was decent port area

Whoever said that meant 14-17sq in PER cube, but that is for a slot port.

You can get away with like 8-11sq in PER cube with aero ports. You have 3 cubes, so you need 24-33sq in of port. Understand?
