Questions about JBL 044Ti wire mesh grill
Well the right channel of my amp produced loud static (popping and cracking) this morning (long story), to the point that the amp went to protection mode. I worried such thing would destroy the tweeter, so I pulled it out to test it with AA battery; that is, by tapping and end of the wire to an end of a battery. The tapping resulted in scratching and popping noises whenever I tap, so I guess the tweeter still works, don't they?
Alas, while I removed the tweeter from the speaker enclosure, I accidentally pushed the 044Ti wire mesh grill harder than it should, so it is now a little bit deformed (pushed in). In order to repair the deformation, I would need to push it back from the other side. But in order to do so, first I have to remove the wire mesh grill from the tweeter.
Question is: how should I do that? Should I just forcibly pull it away? And after I repair the dent, how should I put the wire mesh grill back?
Also, I spotted a pair of spare 044Tis for sale. It look exactly like my 044Ti, with white-colored tweeter's base. The difference is that it doesn't have the wire mesh grill. Is that different sub-model of 044Ti, or is it the same with the 044Ti of my speakers? From what I read here, it seems 044Ti has threaded model and non-threaded model. What does it mean? Is it just the screw hole issue?
Thanks.
(BTW my speakers is 120Ti)
