For my 12W6V2 what size sealed enclosure would be the best? Specs call for .90-1.50 cu. I was thinking of building an enclosure 12"x12" with 1" MDF board which would turn out to be 1.0 cu. Would it be better if I made the box to meet minimum recommended enclosure size or am I good? ------------- Thuan

1.25 cu.ft. is what I would go with for that sub. Remember to adjust for speaker displacement.

And remember to allow for material displacement. If you built your box 12" x12" x12" it would be 1 cu.ft. on the outside but will be quite a bit smaller on the inside. You box volume needs to be a net internal volume. I also would go with 1.25 cu.ft. for this sub.

Im using a site that has a "box calculator", it allows me to enter in the thickness of the material I plan to use. 1.25 it will be, Thanks. What will happen if I made the box to .90 cu? Would it just sound crappy?

It would sound less then its best... .9 is a absolute minimum box size. And the other number is a maximum recommended box size, above that they recommend a ported box. JL ranks its recommended enclousure sizes with a letter grade, remember in school? A, B, C, D, F. Go see you local JL dealer to get a letter grade for your box size, but I think 1.25 is a very good number from my experience. Remember to add the displacement of the woofer. So the number will really be like 1.45 or something.
