Have two 70 speakers.
One where field coil is open, cone is perfect.
Other where voice coil is good, cone is pathetic, speaker works.
I took the pathetic looking cone off the speaker and saw that I might swap it with the perfect cone.
Edge was torn a bit under ring when I lifted it.
Issue is that I do not know if by lifting the other cone off the rim, part of it will stick to the rim and tear somewhat.
I can see in some areas the Cone has lifted smoothly away from the metal but in at some areas it is sticking .
I do not want to go any further until I get some advice here if anyone has lifted the cone off successfully and if they did anything special. Heat, alcohol ? Hopefully someone has lifted these with no issues.
Anyone ?
BTW my complete rebuild came right up, no issues. Just needs a dang good alignment, stations off freq.
This forum is an incredible help ! THANKS !
