I just got this cabinet. On the inside of it, there is a piece of wood dividing the cabinet down the middle with two speaker cones on each side. On the right side, their is cotton evenly distributed over the interior, covering all the wood. But, on the left side, the cotton appears to be only partially covering two sides and the rest is laying at the bottom. Is this preventing me from getting the most out of my cabinet? Is it worth trying to fix?
