Earlier this year I bought some PA speakers at auction. The auction company was cagey enough to list them all as “untested / condition unknown,” but I suspect they had a pretty good idea of the condition.I ended up with a Yamaha SW1181VS 18? 500W subwoofer, a Yamaha Yamaha CW218V dual 18? 1220W subwoofer, and a spare Eminence JAY7010/7011 18? driver. All four of the Eminence drivers were nonfunctional — some dead shorts, some open. This was a bit disappointing.
