Hey so I just built a sealed box for my new jl 12w6v2 and I was going by jl's site for box dimensions. Somehow the dimensions got off and the box is about .15 to.2 cubic feet too big. It's about 1.52 cubic feet or so before the sub goes in and it should have been about 1.34 cubic feet before the sub. So I thnk the box sounds pretty good but I'm wondering if I should add some material to deaden the sound inside to make the sound cleaner or anything else?
I'm hesitant to put polyfill in cause it seems like it isn't good if the enclosure is already above the recommended size...anyway I would appreciate some help.
