3/4" mdf! the popular choice, and it will work well. make sure it is braced, as any box should be. peace

Pick up some liquid nails, wood screws, a counter-sinking bit, and silicone while you're at it :)

Yes, liquid nails. www.liquidnails.com

And why do you want to sound deaden your box? You would only need to sound deaden it if it was built horrendously...

o people told me to deaden the inside to seal it better and it will have a deeper bass

just stick with mdf
use liquid nails and screws to hold the wood together(liquid nails helps seal it)
then us silicone on all the seams(for even better seal)
dont bother to sound deaden unless you really built the box badly(hope not)

thats about it

Okay I'm going to go against the grain here. If you make sure that all of our cuts are accurate and straight. You don't need the liquid nails. Just liberally apply some urethane wood glue on the edges as you assemble the enclosure. Then once the glue dries go back in and seal the seams with silicon if you like. :) You don't really need to sound deaden the enclosure unless it's resonating really bad. But if you want to I would spray some rubberized undercoating inside the enclosure. Then let it sit a couple of days to dry, and air out. :)

ok thanx guys. my dad wanted to try this stuff called gorila glue he can get its suppose to be strong stuff and hes pating for it so i am going to go with that. and as for he sound deadener thanx for tealling me i really dont need it becouse this shop here were i live said it would help it with bass just no matter whut. so thats going to save me $25.

Tell your dad he is a genius :D Gorilla is the best urethane glue I have found. Great stuff. i was going to suggest it. But it's hard to find in some places. Try a test with it. glue a couple of mdf scraps together. Then try toseperate them. I bet the mdf breaks before the glue does :)

like the bottle says, it really is the strongest glue in the world(maybe)

ramos

Sounds like a good idea to me. Just make sure the edges fit together nice and flush with no gaps. The glue is a bonding agent not a filler. :)

Most likely not. Any damping from materials simply takes away the total air you have inside the box, and so causing greater roll off at the bass frequencies.

You probably can HEAR deep bass better by damping, even though the sub isnt creating any more, simply because the high-bass and low mids (if any) in an undamped badly sealed box made the sound muddy.
