Hello.
I'm new on this forum and I looked a lot for the answer but I would need some more advice.
I have 4 L100 with 123A-1 drivers, one of the drivers is noticeably weaker than the others, when I mean weaker, I mean with the four drivers on the test bench with a pink noise generator it's really obvious, I'd say 2-3dB.
Now the DC resistance of the coils are 5.2, 5.1, 4.9 ohms on the 3 "good drivers" and the suspect one is 4.5 ohms.
Question: I know the Alinco magnets are afraid of high power and they get demagnetized, before reconing (expensive C8R2212) I would like to know if the magnet is good, preferably without cracking the thing open
A driver that got overheated could have a lower resistance and in this case I could have two problems, bad coil and bad magnet... is there a way to know? I don't want to drop a new cone in it to find out my problem remains
