Cement box?

he could simply inset a wood ring to accept the screws

x2, that's what i would do. Incorporate it into the mold, pretty simple actually.

I know that someone earlier in the thread said something about cement board. Would this work for an enclosure? Would it have flex or would it be stiffer than MDF? I figure that if it is good enough to put tile on it in the bathroom or kitchen then it would have to be good enough for a sub??????? LOL

Could always go for some super light weight stuff and use fiberblass strands and fiberglass or plastic reinforcing grid with about 1/4" openings. Only problem would be large flat panels. Concrete is good in compression but not tension so when you get larger flat ares flex will be easier and that is what will crack or break the concrete, but with the right amount of reinforcement you should be good. Also look into latex for the mix as well this will add some more tensile strength to the concrete.

Can make some crazy stuff out of concrete, Check out http://www.concretecanoe.org its a competition held every year that I participated in a few times with school. Made a concrete mix that was actually light enough to float in water, got myself a softball sized ball of it that will just float, kinda cool stuff.

Pointless for daily driving, imo. Wood works just fine and is much lighter. You'll be putting extra strain on your car and wasting gas money.

yeah but you would be the talk of the town if you had a concrete box for your subs. I would never do it myself but i think that it would be pretty interesting. IMO

The box was built out of mdf but had marble on the back wall.

yup.. I had to frame it in MDF to keep the marble reasonable to work with.

here are some pics for the fun of it.

seemed to work well //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif
