13" tall, port is 11.25 tall? 7/8" MDF? im not sure how long the port is either, or whether all the measurements are internal or external.

probably around 4 - 4-1/2 cubes, i didnt figure in the port or anything. the 35"x13"x18" box is 4.7125 ft^3

my calculations come up with 3.844, and that is not factoring the port, or basket displacment.

3.679 with 3/4 inch MDF. The first numbers were using 5/8 MDF

This is just a rough estimate and no where near accurate because, well your diagram *****.

2.98 after port displacement. Not factoring speaker displacement tuned to 32hz

It was pain tryin to read it.

Where did you get the box. Did the person who sold you the subs make it??? Or is it pre fab.

those are all external, 3/4 MDF...and the people at GS are *****!that is an estimate for internal volume. correct me if i am wrong, but it is probably closer to 3.5 with the subs in it. the box empty is close to 3.8 or 3.7

Guys, can you explain to me how this is figured out.

Is it wxhxd then divide it by what number? 1728?

and how do you figure out displacement?

and how do you figure out displacement?

Box Internal L x W x H = ? then Divide by 1728 to get cubic feet.

Port L x (W+.75) x H = ?

Subtract the port area from the box area.

Then subtract your speakers displacement. Which can be found in the manual.
