  Removed cloth to replace and noticed that the wires glued to the panel have released. The adhesive appears to be sticky. I tried pushing back the wires into the pregrooved slots however they do not adhear.
     Anyone know what to use to glue down the wires ? Or another suggestion ?
If this belongs in the " Lab please move.

Lots of info in the repair section 2/3rds down the page. 

Easy fix, great speakers.

You can use DAP contact cement with acetone or contact Magnepan for their glue.

Charles,
I had a pair of 3As that needed repair a while back. The treble and sometimes the bass would sound fuzzy and distorted. I noticed loose wires that on the surface of the membrane.  I tried to glue them back but they either came loose again or came off at another spot. I contacted Magnapan and they have a repair kit with new wire and glue. They recommend cleaning off all of the old wire with a solvent (they recommend) and reglue the new wire down. A little time consuming but easy. If I remember correctly  the real hard part was tinning the end of the treble wire. The wire is very thin and has a coating on it. You cannot just solder it down to the contact because the coating will prohibit a good contact. I had to practice with a razor blade about a dozen times in order to be able to skim the coating off to be able to solder it to the contact. Once done, they sounded like new.

If only small area is involved, using DAP (recommended by Peter Gunn) or E-6000 (readily available at any craft shop like Ben Franklin or Michaels) will work. If large areas are involved, an entire re-wire might be in order. Take a picutre of the speaker before you start so you can duplicate the pattern as some of the "coils" are double-wired.  The Magnepan kit includes wire for two speakers, glue, aluminum solder, silicon glue for covering the exposed aluminum wire on the tabs, and instructions.

Definitely contact Magnepan for their glue.  I rebuilt my two sets of IIIas several years ago using DAP initially then using Magnepan's glue.  No problems so far.  Just make sure to either take a picture or draw a diagram of the wiring if you decide to replace it like I did.  It was about $50 for the rebuild kit when I ordered it from Magnepan at the time.

I am in the process of rewiring the bass panels on my MIIIa's.  I did the mids when I first got them three years ago, they were completely dead, and one of the previous owners had hooked up the mid xover to the base panel.  T he bass panels were working fine but I had the tell-tale white spots here and there so I knew it was only time that one of the bass panels would fail.
so I got three years of trouble free use so I am not complaining.  Any way, I am using DAP to secure the loops and the water based NF20 for the wires.  I am doing one run at a time, very slow going.
Removing the buttons was not difficult but a nervous time.  You have to drill out the old rivet and carefully pry off the button.

  Unfortunately for me physically I cannot restore them. I anyone in NY, NJ , Conn, LI would like them as is come and get them. They have the 3.5 ribbons in them. If someone can do the rewiring in the NY area please PM me.

thanks in advance.
