RE: Mechanical buzz in JBL D123-question for speaker repair gurus

Posted by mac55 on June 6, 2017 at 17:02:59:
Thanks. I just tried shaking the speaker while holding it close to my ear, and I don't hear anything that could be loose or anything like particles inside. Mind you, that's not to say I would necessarily be able to hear something from shaking, but it seemed like an interesting thing to try. However, I did find some little balls of debris of some kind (maybe insulation from an old cabinet?) that stand proud on the surround on the back side. Later this evening I will get the tweezers out and remove anything I can see and try again. All advice appreciated.
