Volume of sub enclosure
Can somebody confirm if I am correct. I have a JL 10w3v3 D4.
Based on JL spec, I need a volume of .625 cubic ft (net) and .844157 (gross)
http://mobile.jlaudio.com/pdfs/11232.pdf
So the total volume cubic ft (gross internal) would be :
17.25 x 10.25 x 8 x 8.25 (already subtract 3/4 for mdf on all sides) = 1458.703/1728=.844157 gross internal volume cubic ft?
Just making sure. My last build I did it incorrectly (I used net before taking in consideration for the sub so the enclosure turned out smaller).

if you took time to do that math, leave it at that..
seriously. I used to build HUGE vans full of speakers.. and ya know, for all that math and theory, it never gained me anything, never lost me anything either on anything i had to stretch etc. .
As long as its not a grossly incorrect cabinet it will be juuuust fine. Espec if sealed.. thats almost a no brainer.
Build, install, forget.
Thats how I think sound systems should be..

Sealed boxes are relatively easy to tune as opposed to ported ones. Anything from about .75 to 1 cubic foot should be nice and safe. I usually build slightly towards tha larger end of things so I can tune lower and use less power.
Math and theory is a good guideline in building quality enclosures but by no means should it be taken as the final word.
