reyzor,
Have no fear.
A 'refurbished' Axiom speaker would have all new drivers (or faulty drivers) replaced at the very least. It would also go through the entire QA/QC process again before being shipped out. They are extremely thorough about this. You should have no reservations about the quality of the speaker being received, although i cannot say the same for some of the bigger electronics companies and their often unknown policies on such returned items.
However, the outlet items typically have a physical blemish of some sort. This could be a small nick in the vinyl somewhere or something similar. Of the FO speakers i've purchased, i really had to look for these blemishes.
Take a look at my vp150 "blemish" as well as the single blemish on my one (of two) QS8s. They are nearly impossible to spot beyond a 2 foot distance.
