I have a set of Eclipse Point Source 5x7" that just stopped working (one CX64 ID chameleon woofer too).
Anyhow, the Eclipses were mounted on my parcel shelf and got a LOT of heat from the sun. When I tried to hook them up, the woofer didn't work on one driver. If I push at the corner where the tinsel leads connect to the voice coil, it starts playing again. Anyone have any experience trying to reconnect that? I have a feeling that when I cut away the gooey stuff that I will break the voice coil wire.
If I can fix the Eclipse, I will be happy since I paid $50 for em I think and listened to em for maybe 3 weeks. The Chameleon getting repaired would be a total bonus because it will be another set of 6.5" for me.
So, all tips are greatly appreciated, the goo on the Eclipses is VERY soft, I can probably pick it apart with a toothpick.

I worked at a repair shop that had woofers in a particular home speaker do that - the braid would fail electrically at the terminal end. If I heated the braid right close to the terminal and drained some solder in there, it would work fine and the repair lasted pretty good.
If the failure is at the woofer side, you run the risk of damaging the cone if too much heat is applied (in the case of a non-paper cone) but it may damage it less than pulling the gooey stuff off.
Also the repaired bit should be as short as possible, since it will be taking away from the length of the flexible part of the braid.
I'd troubleshoot it with audio playing, moving the wire while it plays to try to find where on the braid it has failed.

Hey
I have used liquid or paste solder to cure this problem. Just dab a little on the affected area and use a heat gun with a concentrating tip to melt the solder and not the cone or other material. Like NOBASS said, find out exactly where the problem is first.

On the ID, I have no idea where these crappy woofers failed (this is, oh, the 4th one for a joke that did this).
On the Eclipse, however, it is RIGHT on the cone where the tinsel lead is glued to the front of the cone and it eventually attaches to the voicecoil. I have no idea how this attachment works on this woofer, but since the sun messed it up I am assuming it's probably just squished up against the tinsel under there.
So, the problem is at the voicecoil end to make a long story short.
