Just happened to me. What I thought was a DOA (well it was to me) bose feeespace 51 turned out to be a blown speaker that was returned. Guess where I ordered it from?
The BOse tape obviously had been cut, but I didn't think anything of it since my brother works at UPS and boxes get retapped all the time...how I found out about it was when I called AVAD up they said to call bose and they would RMA it...well when I called bose up and gave them the serial number they asked if I was such and such company. After a few questions more it was obvious what had happened. (AVAD and bose track the serial numbers) so called AVAD up and they of course apologized blah blah blah.
Still haven't gotten my credit yet. Funny, I haven't ordered from AVAD in years, then finally had a job where I had to match a previous installers speakers...of course it bites me in the end.
