Posted March 2, 200817 yr what i reccomended wall thickness and material for sub box? Fi Bl 12 loaded (daily) possibly future second 12" .....G
March 2, 200817 yr 3/4" material, either MDF if you're carpeting or painting or perhaps birch ply if you're staining...
March 2, 200817 yr if you go into high powered mode, like push both 12s over their rating a bit, you may want to double up on the baffle, use 2 3\4" sheets but as to doubling up any other wall.. it isn't necessary. You will need to brace for every 12-16" of wall. If you are serious about bracing, use all-thread. That has more effectiveness than doubling up on other walls but double baffle is a good recommendation for, i dont know, 2-3Kw of power maybe?
