Just to clarify, any difference between regular stock, and factory outlet stock would be cosmetic only; a small nick somewhere, a flaw in the vinyl veneer, something like that. It took me two weeks of intense searching to find the flaws (in the vinyl) on my M60s, and they were so subtle that, unless one was looking for them, they'd never be noticed.
Returned speakers are NOT sold through the Factory Outlet. F.O stock and regular stock will perform identically. The only significant downside to ordering from the F.O. is the longer wait for them to ship. When you're eager for something to arrive 6 weeks (my wait time - yours may be different) can seem like an eternity.
