I had no trouble removing them from 7's but these on the 15's seem to be a very tight fit and will not come off. At least not without putting a screwdriver in the tiny gap and forcing them out. I'm afraid that would put a bad scratch on the finish so how do I remove it without damaging the speaker even more?
The driver seems to be broken. When it moves it makes a crackling sound and it isn't anywhere as elastic as the one below it.
