Simple box with 1/2 MDF

Recommended Posts


as long as its no high end 10 with hundreds of watts, you'll be fine.

 

 

Or you can get away with it if you brace it internally.

Is 3/4" that expensive?

 

Its like 6 bucks for the small sheets

 

I thought the same thing. But then I thought back to high school when I was broke as hell. If I had some 1/2" around I might have used it then too. If you're buying a new sheet of wood just go for the 3/4" and spend a few extra bucks.

but then you also save some space with 1/2" on each side so he can have a smaller box. If it's that small of box, 1 brace, if any, are needed.

maybe he drives a Yaris, or a smart car?:D

 

Just one reason to, that and saving a few pounds. No reason to use thicker wood if the 1/2" won't flex! :)

Its going in the back of my Grand National. Weight isnt an issue, but I bought 1/2 a couple weeks ago without re-looking to see what size I needed. I might just use the 1/2 to build and amp rack and buy 3/4 for the box.

 

How would I brace it if I did use the 1/2?

 

thanks guys

There are a few ways to efficiently brace a box for less flex.

 

1. Dowells. Use dowell rods to make cross braces, glue each and screw each end with one screw. Use multiple dowells in multiple directions to make the most efficient bracing.

 

2. Strips of wood. The same way you would use dowells.

 

3. All-Thread. A piece of threaded steel rod that you would run through the box and use nuts and washers to control the flex.

 

Hope this sheds some light on your situation.

coat the inside with fiberglas resin....won't have to worry about $#!t

 

i think that would make it weigh just as much as a 3/4" box

for the size of your enclosure and the sub that's going in it, 1/2" mdf is fine. I'd highly suggest you do a 1" face/baffle though (2 pieces of 1/2" mdf). Good luck with it!
