I've been trying super hard to get my box calculations right. Can someone confirm these #'s?? I really hope I'm on the money. :lol2:

:thanx: in advance.

Box is 32" tall, 15" deep, and 18" wide. Port is 16.5" tall (internal), 2.25" wide, and 40" long. Looking to be 31-32hz, 2.25cu.ft. after sub and port displacement.

:fingers crossed:

With the demensions you gave I come up with 2.4cu' net vol. tuned at 30.4-- of coarse you did not say what sub or the displacement so after you subtract that the net and tuning will change a little. Hope that helps.

wow i can't believe i forgot to throw in the displacement. lol

THANKS!

I used a displacement of .15cu.ft. for the sub (guesstimation)

How is that? I'm glad to here I'm close!

With the .15 disp. I come up with 2.25 @ 31.4--Looks like you are about were you wanted to be. Of coarse I am no box designer, but I can plug in #'s like a mad-man. :woot:

Its 2.68ft^3 @ 28.4hz after all displacements.

What all did you use to came up with that? Box won't have bracing or a double baffle either.

Definitely not saying you're wrong, just curious.

:lol2: i love the discreet post edit. no problem though man, i really appreciate the help. plus when it comes to what i'm doing, it won't be for competing etc. so anything close enough is no problem.

Sorry, did not take into consideration for the common port walls, went back and checked and that made the difference. Again, sorry for the fail.
