I used to own the same speakers and my drivers didn’t look like that around the edging they look glued to me but I’m not an expert, everyone else on here would be able to comment more I guess, but they don’t look right to me.
For sure 100% I wouldn’t want to have drivers in that particular condition they do look like they have been repaired to me but I may well be wrong.
I personally would want to send them back with respect.

A pair of the 5000.2 went on their for £300 a few months ago and that was a bargain of the century!
