I just built a subwoofer box for my JL Audio 12W6 V2, the recommended net
volume in the JL site (PDF) is 1.25 cub ft. but due to faulty calculation,
I built mine as 1.225 cub feet.

Question 1: Do you guys think I need to rebuild the box to get it perfect?
Question 2: I am wondering how different will 0.025 cub feet affects the
sound quality? will it be big difference?

John

I'll defer to people that have more experience with ported boxes, but
you're only talking about a two-percent variation here. Was your
error in the size of the port, or in the size of the rest of the
enclosure? If the entire .025 cubic feet shortage is in the port, you
might notice the difference, but maybe not.

Sorry, I forgot to say it's a sealed box. The error was due to wood cutting
measurement. Do you think .025 cubic feet will be a problem?

I dont know where I got the idea that you used a ported box.
Don't even think about re-building a sealed box to correct a 2% sizing
error. Sealed boxes are pretty forgiving up to a 10% variation. If
it would make you feel better, one pound of polyfill stuffed in the
box (fluff it until it's about the density of cotton candy) will make
the sub behave as if it were in a larger box.

You'll be fine. That small of a variationin a sealed box is nothing to
worry about.

0.025ft.....
