Alrite So I bought a Fi BL 18" sub and I wanted to kno something. What if I buy a Fi BTL 18" sub as well. Can I use both of those subs in the same box or I can't ?

Thanks!

x2, absolutely NO

They are two different drivers. The BTL's suspension is stiffer than the BL by 17.9 l, that means the BL's suspension will move a lot more and make it prone to mechanical failure if put in a common chamber enclosure. If they are separate you won't have a problem, but it's possible they have a diffferent "sound".

Why would you want to do this, buy two of the same subs
