Picked up a couple 8" woofers at the local thrift shop. They were in a sealed unmarked box. Tried searching using the numberamp on the magnet without much luck.
Hmm, reminds me of some cheap Altavoz prosound/mobile audio drivers sold locally way back when. Really good value for the day, similar to some of RadioShack's better drivers and still have a pair of wide range 6.5" in small two way wall monitors out in the garage.
