oh belive me, that box is glued!. It is glued where the wood meet the other board, and then again along the corners on the inside of the box. i used power grip or something like that. I threw the tube away already. But if you ever seen the commerical where this guys neighbor is working on his house really early in the morning, and wakes the guy nextdoor up, and he walks to his house and grabs the guys hammer that he is banging on his house with, and runs a bead of the caulk along the hammer and glues it to the guys ceiling then walks away.
We did cheap out a little bit tho on the wood, we used a old box we made for some dd 3515s that was 11cubed tuned too about 45 hertz that sat in a mazda mx3 firing foward.. That was a big box!!! heres some pics I took with my cell before I got uncheap and bought a digi, but it will give you an idea of the box size... PS: Dont diss the audiobling, right now I have more respect for a 2400watt rms amp at 15.5 volts for $400, then the spl dynamics that is 3000watt rms at 14.4 that costs almost $3000!
