Well today I scored a Mesa Thiele with the EV12 200W speaker. I tried it out etc and it was fine.
Then once I got home I noticed that in the center of the speaker where there is a dome like piece of rubber/foam there are some cracks. It happens to be just where the "EV" Electro-Voice logo is like in the pic below.
Is that something bad for the speaker? It sounded fine to me today and honestly the other guy was kinda shocked. If it's anything bad he said he'd take it back and give me a refund with no issues.
So am I just stressing out or is that thing crucial to the speaker? I'm gonna try to take a better look tomorrow by removing the front cover on the cab but even that is a bitch to remove.
That dome is just a dust cover. You should be fine.
