What should be my subwoofer box thickness?

[Subnoob2002]

Im building my first subwoofer box for a 12' driver, which im going to use in my home theater. I was thinking about building it with with 1' mdf and 1' of padding, is this enough or is it too thin?
thank's in advance

I've build my 15"s with 18mm MDF and the double in the baffle. I recon enough bracing counts for thicker walls.

These are sealed, so for the padding I just stuffed enough fiberglass wool so I would be packed yet not super tight.

For vented it seems 1" is good.

Great, thank you for the response
