Fill it as far as what? Resin doesn't do too much of anything except to seal your box tight. People say that it reduces turbulence, but in reality, you can potentially even lose output from resining. If you mean as far as damping materials go, it really depends on the enclosure, but closed cell foam (egg crate), Dacron, fiberglass (insulation i mean), and pillow stuffing all work well to increase the low end "clarity" a bit.i was wondering what i should fill my box with? should i put a layer of foam in the box?
