Need help in sub box sizing

[duckmanjbr]

Forgot to mention the fiberglass.... If you're planning on working the box out of fiberglass I'd recommend two things. Fiberglass doesn't work w/ internal reverb as well as HDF or MDF. If you want to use fiberglass I'd recommend at lease one side be wood and use some dynamat inside on no more than three sides of the enclosure if you can. You don't need more than three sides and if the sides aren't flat even using it on one side will help you out a lot! Hope this helps... Check out my last build.....
