alright then, I'll try to help out.

I have factory outlet M22s. One of them appears to be flawless. The only thing that I was able to find after looking REALLY hard was a slight slight gap (more like a sliver), where the vinyl doesn'y quite meet up exactly in the top left corner near the back of the speaker. On the other M22, the vortex port was improperly glued, so the ridges inside don't line up exactly.
