I just pick up a pair of ADS L780/2 speakers at the local Goodwill store for $24.99 all drivers look intact and they need to be clean but not major scratches on the cabinets. I will have to wait till I get home tonight to fire them up. and see if they work.
There is a bit of rust around the woofer but no major things other that they are dusty. Any recommendations what to look before I get them connected to the amp.
