The cabinet is scrapped now. It had been sitting in water for a while, and the bottom was held on with nails. The evidence that it has been through a house fire is clear, look at the nose of the bullet. That stuff doesn't want to come off, and the back of the woofer is coated with the same stuff. I was thinking that at least I'd salvage some hardwood for some other project, but to my surprise, the entire cabinet is particle board. Not a scrap of real walnut anywhere in it.
