Bad idea?

Let's just say you made mold for the cement.. Would it work well?

I just had some reading comprehension test at school talking about Thomas Edison's Cement houses... So I just thought of this out of curiosity...

If you plan on competing, it isn't legal.

Never going to compete... Just for personal daily use.

If you do it, get some of that garage floor coating for the exterior of the box!

Yeah, lol.

How thick would the cement have to be?

I would look in to the mixes that are used in concrete counter tops, you would ahve to use some kind of reinforcement (chicken wire, 1/4inch smooth rod ...) and add fiber. If you google concrete counter tops, you will find recources for premixed concrete that is high strength and will not need to be more than 1.5-2 inches thick

Hmmm, maybe this will be for only one sub, and sealed :)

I'll look into that stuff!

I need to make a new box first... I might try this over Christmas, or wait I mean "winter" break..............

he could simply inset a wood ring to accept the screws

You can buy cement screws... Also when molding it you have all the screw holes laid out, and the pre-drilling it actually sticking something through the mold to create a hole in it.

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

lol sounds kinda intuitive but i don't the weight to sound ratio wouldn't be too good for a daily i remember my local shop having like and s-10 with a camper i think with the whole bed concreated in for a system never got to hear it but yeas

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 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.
