Ok guys so I am getting another SA-12, which means a new box (as I have 1 at the moment). It will be roughly 4ft3 and tuned to 34hz slot ported. Now, would coating the interior with fiberglass resin help improve box rigidity? What about bracing, and how would I go about doing that? Would double layering the baffle and the back of the box (where I have a bit more room) help?
