Port Area

ok so make sure i've got this right. If i go with a 2 or so net cubic foot box, after i add on port, sub, and bracing displacements it shouldn't be over 3 cubes total correct? And that 20 square inches each? is that for sub or per cubic foot.

you should have 3cuft net after everything.

and 20sq in per woofer is ideal.

using your dimensions... 35.75W X 11T X 25D you've got 4.42 cu.ft.

Build the box that size with the 4 8's along the front of the box with a slot port along the bottom right below them.

The vent should be 34.25W X 1.25T X 18L. That will tune around 37. Divide the center of the vent with a strip of 3/4 for a brace.

That sounds like a winner.

Ok, now i'm confused. First to go with .75 each which adds up to 3 cubic ft, but now you are saying that the 4.42 cubic ft. box would be fine also. Sorry to be a pain, i just don't want to risk this poor fellers subs, if they were mine, i know what i would be doing the box a little differently.

4.42 is before sub@port displacement

[banginsebring07]

ok i guess i misunderstood you then. I though when you said .75 after displacements i thought you meant that was after adding them on. So it would be like .75 cubic ft. and then add on the port and sub displacement which would make it for example like 1.1 cubes correct?

okay sorry for all the dumb question i dunno what the hell i was thinking all week. I think its the lack of sleep. But thanks again, durr on my part.
