Can someone here verify my numbers for my sonosubs volume. (math was always my weakest subj.)

16.5" OD
16" ID
20" H
.25" wall thickness
My calculations give me 2.27f^3. Is this right?
Thank you to all that respond. JB

I get 2.33 Cu ft. That is using pi X 64 X 20 divided by 1728.

Is 20" the internal height?

Greets!

Assuming the 20" height is i.d.:

(((16^2*pi)/4)*20)/1728 = ~2.327105669 ft^3 minus whatever Vb the driver, etc., takes up.

The actual height of the tube is 22", but the total thickness of the caps are 2" so I am deducting 2 from the height. 20" will be my internal volume. Thank you Cal.

As G.M. has pointed out, you will need deduct the volume of the driver from the box.

...and don't forget to calculate to 9 decimal points.

Yeah, that's the problem with electronic calculators, they don't round off unless you use scientific notation, which flummoxes too many folks to use on most forums.
