I have a JBL D123 speaker which I use in a 5 watt tube guitar amp. This is not unusual as the D123 actually has a good reputation for use as a guitar speaker.
In any event, it has a very light buzz on certain notes. I'm not sure when this started, and it may have been there all along as I have had this speaker for a long time but only started using it more frequently of late. It's not terribly objectionable, but it's there. The speaker exhibits no rubbing when physically moving the cone, so I am wondering if someone can tell me what it might be or how to approach the problem. I'm pretty handy mechanically, and in fact recently fixed an 8" alnico speaker that had a blister in the voice coil which was rubbing. I took the horseshoe magnet off, glued the blister down, and put it back together and it works fine. Mind you, I know the D123 is certainly different, and worth more, so I might hesitate to perform surgery with the same recklessness. I cannot even see how the cover would come off. I would be very grateful for any thoughts or ideas.
