Can anyone help me with a ported box design for an 18". Here's the measurements I have to work with, I know it won't be optimal for an 18" but it's all the room I have. I'll pay somebody through paypal if need be.

22"H x 40 1/4"L x 21 1/4"W

Please help me out, Thanks.

WHat sub?

18" MT it kills me not to have the optimum space but hopefully 5 c/ft or so will work.

Here's some specs:

It's for an 18" MT

Mounting depth is 10.75"

displacement .25c/ft

Tuning I want at 32hz.

I'm not sure about the volume and maybe 90 to 100sq inches of port?

Go with less port... Try for around 70 sq in. When you have limited space its much better to have the right airspace than a monster port.

he can actually get away with 60square inches of port

it wont as long and it wont take up much space

80

So in this case, the box that iDesign made is perfect for the amount of room I have right?
