Returned speakers are NOT sold from the Factory Outlet. They are sold cheaply to staff, family, and friends. No Factory Outlet speaker is a return. Factory Outlet speakers have some small cosmetic flaw that occurred in construction, packing, or shipping, but in all other ways, will perform as new.
My M60s, for example, had a very subtle mark that was created when the vinyl itself was manufactured. It was 2 weeks before I finally found these flaws, and nobody ever noticed them.
