I hope I'm following protocol here, and thanks in advance for any replies. I've searched the forum and found some interesting posts about various repairs to the 044 tweeter but nothing that addresses my issue.
I recently acquired a pair of JBL L112's for $40. The guy made me haul off his Hafler DH500 as part of the deal, but I've got good springs on my truck so I didn't complain ;-)
One of the L112's sounds great, but the tweeter wasn't working in the other one, so I pulled it and discovered the thin wire from the voicecoil had come detached from one of the poles. I figured I ought to be able to solder it back together, but couldn't access it without removing the magnet and diaphragm from the outer cover.
I'm embarrassed to say I can't recall now whether the magnet was already off center when I did this, but it certainly was by the time I tried to put it back together. It's strong enough that I can't move the steel outer parts with the magnet sandwiched in there, at least not by hand or with simple hand tools. I haven't tried putting it in a press yet as I'm kind of afraid I'm going to crush the magnet trying. I can get it together the way it is, but I'm not sure what's supposed to keep the magnet/steel sandwich properly aligned, unless the screws are supposed to go all the way through the steel into holes in the magnet that I can't see the way it is now. I can get it together the way it is, but it doesn't work, and I'm not sure if that's because of this issue or simply because my solder job is a hack. I do get continuity across the poles, but I only measure a fraction of an ohm; again, I'm not sure if this is because the diaphragm is not mounted in the magnet properly.
I see in other threads that people are doing diaphragm repairs, evidently without running into this problem. Should I accept that this is probably why the thing didn't work in the first place, or is there a way to get this thing centered properly?
Thanks again!
