Ported box volume

[BoxNoob]

When building a slot ported box do you count the port area as part of the box volume or is the port completely separate?

Since the port is actually part of the box/internal do you just subtract the "bracing" of the port, or do you create a 1 cubic foot box, then add the WHOLE port including the bracing/area of the port?

You do not include the port area as part of the box dimensions. Internal box area ends where the port begins.

You'll want to focus on net volume after port, sub and bracing displacement. I normally have two set dimensions, say height and width, and leave depth open. I figure up what the displacement of my port will be, what the bracing and subs will take up then by multiplying/dividing I can determine how deep the enclosure will need to be to yield the net volume I'm after.

ahhhh..

So just to make sure this is correct.. when I do my calculations, 28HZ is approx 50 inches long (11.5 high x 2.75 width) material 0.75.... so If the main chamber is 2.0, then I need an additional 1.2 just for the port area, so the box would be 3.2 total area including port. (currently not calculating displacement from subs..
