Can someone tell me if this box is 3cf after displacement

I am having a box built and my friend says the internal volume will be 29.5 inches wide, 15.5 inches high and 11.75 inches deep. My sub displaces 0.25 cubic inches

Is it possible to tell me if this box will be 3cf after displacement

That's 2.85 cf

2.859

So this box here is not 3cf sealed

so since the box is double baffled, does it now make it 3cf after displacement. Sub displacement being 0.25 cbuic feet

I got 2.86 cubes after sub displacement.

11.75 x 15.5 x 29.5 = 5372 cubic inches = 3.11 cubic feet - .25 = 2.86 cubic feet

What sub are you running? jw

So seeing how everyone got 2.86 cf feet without taking into consideration it's double baffled, doesn't the extra 3/4 inch the sub sticks out add to the internal volume?

all the air space you will be gaining is an extra sub hole cut out's volume, added to the entire interior volume.

So you will be adding ~~.067 cubic feet to the interior of the box.

~2.9 cubes total.

Well i asked for 3cf max since thats what SI recommended, So 2.9cf is good enough. SI recommends 2.3-3cf
