Box is too big for 2 L7 12's....

I've got my 1 L7 in 3.5 cu ft now, sounds amazing.

7cu ft is too big?

What do you recommend?

I would say 5 cubes for 12's, MAYBE 6 at the absolute MAX.

What about a chamber for each?

Would a 3.5cu ft chamber each or 7cu ft chamber for both be any different?

Who keeps telling people this? Speakers work best in a specific airspace. Larger does NOT mean better. It never has, and it never will. All you'll do by going bigger if you don't know what you're doing is going to bottom out the subs and reach its mechanical limits.

Oh wow, so if I put my 10" sub in a 25 cube box that means it'll have better low end than if I put it in a 3 cube box right?

No, that box is far too large for a pair of 12's.

The same (if not BETTER) performance can be had from a smaller (properly sized) enclosure.

For the people saying it's way too big, have you actually heard L7's in a box that size? If you have and you can really tell its too big then I wouldn't do it.

I made a 2.75 @ 33 hz box for (1) type R 12" sub and people said it was too big, but after hearing close to the same setup, but in a smaller 1.80 @ 34hz I actually liked the sound and output much more of the larger box. Thats just my opinion.
