Would lining JL's H.O.12w7enclosure with Polyfill make it sound any louder/crisper or more bass/Spl?

-Have to open up the box anyway to silicone a small leak and was just wondering if I wuld gain anything or if it would sound any better if stuffed it or lined it with some leftover polyfill I had from another build I did. Tjanx.no major difference.

Might play a touch lower.



Polyfill makes the box perform as if it were somewhat larger. How much depends on the quantity of poly per cubic foot. IIRC using about 1.5lb of fill per cubic foot nets an effective volume increase of around 35%.



If the subs would benefit from a larger box it could help a little, but if the box is already the ideal size adding polyfill could actually make things a little worse.i do not about the h.o. box in particular . but i know some jl audio boxes come with polyfill in them already.so if polyfill would help then chances are it already has it.
