Besides caulking the seams, what else can been done to assure the enclosure is sealed tight? Sound damping material?


And where is a good place to get vinyl to cover the box?

 

If the box is well built, caulking the inside is all thats needed.

 

gently push on the cone... its should come back slowly if its sealed...

 

I've always put the box together with liquid nails and then screwed it together. No problems so far.

 

I use silicone. Used it on the past couple boxes I made. Deffinetally makes the box air tight. I think its either elmers or g.e. glue I cant remember. But its the stuff thats rated the best for everything.

 

yeh I agree with whitekid silicone is the way to go

 

I fiberglassed all the inside corners.

 

Mitch got it right. If it's a sealed enclosure, push on the sub firmly. The cone of the sub will slowly come back out if there are no leaks. If the cone just comes right back out there is an air leak either on the box or surrounding the sub. When building a box I suggest using wood glue along the edges of each face of the box. Any wood glue will do. Be sure to screw the box together tightly and then use silicone caulking on the inside of the box. If the surround of your sub is made of foam, let the caulked box air out for a day. The silicone fumes may eat away at the foam surround!
