Hi all, my first post. Own a pair of KG4s in what I think is great shape. I'm the 2nd owner and pushing them with a Marantz 2252B receiver and all sounds really nice. On top of regular listening, I started using this setup while playing my TD-3 e-drums ocassionally. It all sounds great and I am not playing too loud either, but lately I noticed that the right speaker had a sustained buzzing sound when I would hit a low or floor tom... Sure enough, I started hearing it all the time, while listening to the FM radio, iPod, even talk radio. I took the grille off and it was coming from the bottom K8K woofer in one of the speakers. It still works, but the rattling lasts about a second after I hit the tom on my drums and it's bothering me.
I read some posts here about lightly holding hand on the white part of the woofer cone while hitting my tom and it sounded like the buzz was coming from about 10 oclock area on the woofer, and if I would hold the woofer cone at about 4 oclock and hit the tom louder, the buzz would go away after a few hits. I would play fine without it for a few hours and then the buzz would come back the next day, so I am not sure if my woofer is damaged or is this something that will go away with time. Why does holding the woofer fix the buzzing anyway?
I tried to swap the woofers to test, but after taking the screws out, it seems the woofers are glued to the cabinet? Am I missing something about taking this apart or should I just pull harder on it? Can someone give me tips on disassembling this as well please
Thanks in advance!
