I need a tweeter surgeon…anybody?

I was messing around inside my Frazier Mark V’s and decided to pull the rubber cap off the back of the horn tweeter…bad Idea. I broke the lead to the negative voice coil winding. I tried to fix it myself but only made it worse. I had to lift the material covering the voice coil in order to expose some of the lead but I don’t want to make it any worse so I am asking for help. If anybody here can repair this I would be glad to reimburse you for your time and work. Here’s a picture of the tweeter:

the copper wire off to the right is supposed to connect to the voice coil.

Ok I tried to repair it myself and it worked but now the tweeter seems to have a slightly weaker output compared to the other.

What i did was twist together three individual strands of speaker wire, wrapped those around the thicker copper wire that originally connected to the voice coil lead, then scraped the visible lead to expose the silver part of the wire, then I put the twisted strand of speaker wire right above the tinsel lead and screwed it back on to the horn. I have some questions though.

This is obviously not the best repair job but it is good enough to produce sound, but I want to know if, for instance, there is really only one strand out of the three twisted strands making contact with the lead, does that mean that some of the electrical energy is being wasted running through the two other strands that are not making contact thus leading to decreased output?
 
No, no energy wasted. Be sure though, that those free leads are not touching anything else. Trim them off with small wire cutters - or, if not available, finger nail clippers. Did you get a good solder joint where the lead meets the tinsel?

I’ll have to go back in there and trim. Unfortunately I wasn’t able to solder them, they are being held in place only by the pressure from the tweeter being screwed back onto the horn. So the lead is basically sandwiched onto the tinsel. I had tried to solder the tinsel but it just melted/evaporated as soon as I put the iron on the thicker wire lead, which is why I had to peel away the dust cover and expose the tinsel. Not the best repair job, I know. But it will do for now. I would like to have it professionally repaired at some point to maintain the integrity of the unit, but I don’t want just anyone to handle this tweeter because I doubt I would find a replacement if an inexperienced repairperson were to kill it.
 
Spend 40 bucks for a working replacement and be done.

If fear of the worst motivates you, buy them both as the seller has 2.
