View Full Version : Help me figure out my cubic ft

OK my dimensions are
48"w
16"h
28" d

and the actual (inside the box) dimensions are
46.5"w
14.5"h
26.5"d

that gives me 10.3cubic ft and 10.1cubic ft per sub/chamber.

This box is for two 15" L7s, each has it's own chamber. What would be the exact cubic ft after port displacement.

Ports are two 6" aeroports 22" Deep.

http://www.the12volt.com/caraudio/boxcalcs.asp#porThanks but that didn't help much. All it really does it let me know how much I need to cut my ports and my total cubic ft (w/o ports displacement) which I already know. I want to know how much it will be after port displacement.

If you can't do simple math... then you should go kill yourself.

Fill up the box with water and tell me how much more it weighs. Then I can help you:cool:

nGOK thanks for the help:rolleyes:

Im not sure of every thing though...my ports are 6" by 22"deep and it's two per sub. So would that be 264inches of port per sub!!!:eyebrow: Can't be....I got this by doing 6" (diameter of port) by depth (22") and got 132 then multipled by 2 since it's two ports per sub...it can't be right though and if that's right then I have too much port area (i think).

ARE YOU ******* ILLITERATE????

Jesus christ, I mean seriously...

DID YOU PASS HIGH SCHOOL GEOMETRY?

NUMBSKULL...

I am seriously baffled, I didn't know ANYONE with HALF of a highschool education could be this stupid. For real. This is a new low.

You are a fuktard.

I know in order to get square inches of port on a normal slot ported box you do the depth of the port times the width and there you get your port area.

I am seriously in disbelief. This is ludicrous...

WOW. You really ARE an idiot... most of the time I was just giving you a hard time... but you REALLY ARE a numbskull.

Port area of a slot port would be width x height, which would give you the area of your port if it were a flat plane.

For a cylindrical port you would find the area of a circle, which would be pi*r^2

But port area doesnt give you volume... So I dont know why you are worried about that as it is.

And I agree, you are retarded.

Search google for the forumula to find volume of a cylinder, it is that simple.

why am i helping?

anyways port area of a slot port is length * width

port area of a round port is pi*r^2

displacement of a round port is pi*r^2*h/12^3

Oh well from several threads I read, that's how it was. Now that I look at some old plans I have, it makes sense.

if you gotta a scientific calculator, all you gotta do is substitute 3 for r and 22 for h

I guess your caraudio skills are based on how long you have been on ca.com.

Im pretty sure I'll be ok for a 15" L7 as far as an cubic ft goes. I just wanted to know what exactly it would be.

I'll have to agree w/ ng with your retardom. I gave you the **** link to your answer but you couldn't figure it out. may this box fall apart also.
