Hello- I have a pair of these speakers which are in need of a bit of crossover restore. I had replaced the L-pads in both as they were beyond redemption. Both speakers were working but I had wanted to tweak the resistor values. While inside the cab, I thought that inductor looked like it might have had a cold solder joint. I tried to reflow the joint at 400, 450, and finally 500 briefly but to no avail. I am unable to get the lead from the inductor to solder to the tag on the outside! I have a pencil tip on my Weller station now but I have several other tips available. Is that the trick for this thick inductor wire? Even higher temp? was afraid of damaging the contact even though I have the heat clips on ther other side...any help is appreciated!
