what is a cubic foot?.....seriously? a cubic foot is 1 ft. x 1ft. x 1ft. also known as volume aka how much space something takes up aka 7th grade

so eexplain this, if my sub needs 3 cubic feet would it be like 3ft x 3ft x 3ft ?

Think of it as actual little cubic boxes you can pick up.

A 1 cubic foot box is 1ft x 1ft x 1ft.

Now if you have 3 of those all lined up, it is 3) 1cubic foot boxes. For a total of 3 cubic feet.

Now if each one is 1ft x 1ft x 1ft, and the are all lined up on your floor.

The will still only be 1ft high x 1ft wide, but will be 3ft long total.

thankyou,thankyou,thankyou! this really really helped me understand a lot more of what im asking, im still a bit confused but this did help me a lot. can you possinly answer me this? my sub being ported requires 1-2 cubic feet, any possible way of explaining to me how i would go about getting my height annd wieth and depth ?

Just ordered my danged glue and dust caps, haha.

Also to the OP.

I used to run 12" MTX 8000s. Small sealed boxes sounded great with them. But they pounded in about 2.5 cubes for each woofer ported with a single 4" round port for each woofer.

For a single 12 you can make the box about 14" high so the sub can fit. Then you need enough room to fit the sub and port so you can make it about 20" wide lets say for starters.

So thats 14" x 20".

Now we figure our depth.

Volume is depth x height x width.

So 2 cubes is 12" x 12" x 24"= 3456 cubic inches.

Our 3 dimensions multiplied should come close to 3456. and we have 14 x 20 already which equals 280

So then we take that 3456 and divide by 280 to figure out what else we need. And we get about 12.34", This is how deep we make the box.

So we figured 14" x 20" x 12.34" will give you a 2 cubic ft box that can fit a 12" sub and room for a port on the baffle.

You will have to make the box a bit larger though because the sub and port take up some of that airspace. Thats why a 2.5 cube box may do better.

So lets add another .5 cubes by making the box deeper.

2.5 cubes is 4320 cubic inches.

our 14x20=280

4320/280=15.43"

So make the box 14"H x 20"w x 15.43"D for 2.5 cubes

haha, no probs. Hanging with girls is a very good thing.

I'm gonna teach my girl how to build a woofer.
