ok so i have a sealed enclosure from futureshop and i also built one myself, no specs or anything, but for 2 15"s, i was wondering if silicone would be good to seal the corners and all inside the box so it closes up gaps thats the air could pass threw from..if not what should i use?

 

a good box only needs glue, and screws to hold everything together while the glue dries


that said I've also made not so perfect cuts before..... if the gaps are very substantial I'd use bondo or better yet kitty hair fiberglass....

 

Silicone is fine i use it inside my spl box.

 

I use a latex based product called Alex Plus, no matter how good my cuts are, I run a bead down each joint.

Just make sure and let the silicone cure before putting a sub in, as some products can release nasty fumes. I have heard that some of the fumes can effect the glues used on a sub, and while I'm not sure whether that is true, I would rather not find out the hard way.

 

with a 15 ur pushing a lot more air and more strain on the box, best bet is to get some fiberglass resin and coat the inside of the box, it will seal it up good and make it bullet proof as long as u actually screwed it together lol
