How to calculate port size, length, etc?

How does one determine the size of the port tube, length, etc. when building a vented sub box?

Thanks.

I use the size/length that is given in Unibox when I design a sub.

Where do you find Unibox at? Thanks.

When using Google, it's the 3rd link. To make it easy - link.

If you don't have Excel, you can always use WinISD Pro.

If you get this thread moved to the DIY section and post your plans, you will get a lot of help from some very experienced sub builders.

You can also take a look at WinISD Pro, which I personally prefer.
