    Default Sealed fiberboard sub box?

    Hey guys! It's been a while since I was on here, it's been a busy summer. I'm still driving an '01 S10, and I still have the 12" Xplod subwoofer in the cab. My question is if it's possible or wise to build a sealed box using fiberboard. I have quite a bit left after I built the potted box, easily enough to meet the space requirements for my sub. The reason I want to build a sealed box is because I'm told it will provide tighter, cleaner bass. Any help would be awesome! Thanks guys

    If at first you don't succeed, then skydiving is not for you.

    that's what most of them are made of. I dont see any reason that wouldnt work. RTV sealant should work nicely in the seams.

    I've always used MDF when I build my enclosures...

    Thanks guys, I guess I'm uninformed and a newb to this but all of the sealed boxes I've seen were made of fiberglass. The rtv is an excellent suggestion, but is it a good idea to use that to seal the sub itself or should a get a ring specifically designed for such a purpose?

    I've always used MDF as well. I like my sealed box because just like you said it is a tighter cleaner bass. My interior of my truck doesn't rattle as much and yet I still hit a 135.6 db this weekend

    Nice! That's exactly what I wanted to hear, as the top notch high quality plastic in my truck doesn't sound too good.

    Haha I feel ya there man! I fitted my box so it fits snug in my back plastic then both my seats slide back into it. Keeps it solid ha

    Sounds slick to me, now Im really wanting to get to work on a new and better box. It's been since March that I've done any woodwork, since I injured my finger, but there is nothing like a project to excite oneself into getting busy.

    That would be sweet! When i first got into audio I was like hey a box is just a box but its amazing how much a difference it makes! A sub is only as good as its box. Here's the most recent one I made. Amp isn't mounted on it in the pic though

    That's impressive, I'm assuming it's a sealed box? And are those 10's?
