so i am going to run four 10's and want the box 4.2 before sub and port displacement. on the average what would the box be after this displacement? also i was thinking of having the subs on top of the box firing up towards my trunk lid and the port firing towards the back of the trunk.

i was thinking

H: 11--12'
L: 30--32'
W 18--24'

what would this come up to??? i have no idea how to find out. i tried a calculator i found off google but it was no help and they all seemed to give different answers. and it will be made with 3/4' MDF

all info would be great!

Port displacement for a box that sized is usually .25-.5 cubic feet. Sub displacement is anywhere from .018 to .25.
At the maximum dimensions listed, you'd only be able to achieve a 4.16 cubic box, before any sort of displacement. I'd suggest an aeroport, since they take up less space due to their efficiency.

will it sound any different from a slot port? will they be flush with the box or sticking out? and do they cost alot more?

11.25 x 31.25 x 23.25 is going to give you 4.73 cubes...

You're right. It does. However, that only accounts for ONE side of the box. You have to subtract 1.5" for 3/4" wood (.75" wood x 2 = 1.5").

I can read. I'm saying that's the most you can get with said measurements.

CJ's a troller. It's what he does.
He doesn't realize that I've been trolling this forum a lot longer than he has.

why are you always wrong? isnt that what you said to me when i said clipping creates excess heat?

.018 to .25? wtf kind of subs are you thinking of douche? a typical sub is about
.05 to .10 but it depends entirely on the sub.
your math is right but i wanna see a 10 that takes up .25 cf each, a massive 12 takes about .08-.18. some are slightly more but not by much. as far as box design, use a shared space design to maximize air space.
slot ports have been proven to be the most efficient as well as strengthening the box., it has been discussed many times. and they are far cheaper because they are built into the box.

oh wait I forgot man , your 18 yrs old you have massive amounts of experience :) my bad all mighty one lolz
