I tried to lay the speaker on its back. Still same scratching.
I took it off, and when I press it down with my fingers, I can’t reproduce it.
Considering to cut off the dust cap and use some air pressure.
As you can see from the pictures I doubt that I can source the driver.
Thanks for the welcome back ?
And now for the million dollar question:
what song was I listening to when I noticed the issue?
