Concrete is best because it wouldn't flex like wood does. No flex = more output.

Not true.

I don't see being able to feed that much power, because concrete is good in compression....any tension and it cracks.....on the back stroke of the woofer, the box should shatter:wow:

Here is a pic of the marble box I built. Worked well //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

and here is a marble wall we made for my team mates x-cab ranger

All this had in it were two cheapie Alphasonik 15's and a fusion 4000 amp.

Concrete works. Gas mileage sucks //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
