I had a 12" woofer quit in one of my 2.5`s, so I thought that I would send it to Bill Watkins for repair. Now, I have shipped vintage drums,cymbals and old stereo gear all over the US without any damage. I have learned a valuable lesson on how not to ship a speaker. I thought I had packed it up safe and sound. NOT ! Bill sent me pics and I talked with him on the phone. The speaker was not secured well enough in the box and it was totally destroyed ! (his words) The magnet shifted and severed the voice coils. Bummer. He can`t repair it and does not have a replacement. So I am looking for a replacement, no luck so far. If a ever ship another one, it will be bolted (not screws) to a wood frame with at least 8" of bubble wrap around it. Bill told me that he has seen this many times. (shame) So I thought that I would pass this along, maybe save someone some grief.
