Im currently building a sealed box out of solid 3/4" Walnut hardwood. I will be coating the inside with fiberglass resin to fill in the knots and any other possible air leaks. My question is has anyone ever done this before, and if so how will it work?? Im building it at school and I needed a project to work on so if its not really a good idea its not a loss to me. BTW its 2.5 cubes and is going to be housing my 2 12" CVR's.
