I just received back (2) drivers from Bill that were absolutely fried. He even sent me pictures, (which, if I could figure out how to post them, I would) of the awful shape they were in. I wasn’t even sure he could fix them, but he assured me he could.
I got back two of the nicest, rebuilt from the ground up, drivers that could ever be done. They sound like new and saved a really cool speaker.
I’ve sent Bill quite a few drivers here recently and he is indeed a "National Treasure!"
