I have a Velodyne F-1800RII that failed. One wire that connects to the voice coil on the speaker has disconnected. There is a tab on the tube that the voice coil is wound on where braided cables attach to the voice coil wire. The braid and connection is then sealed under what looks like white epoxy. That epoxy separated from the tab it was one, allowing the braids to move and break their connection to the voice coil.
To repair the connection, it seems I need to remove the epoxy from the tab to get to the voice coil wire I need to solder. Does anyone have any hints on how to proceed, which I imagine means removing the epoxy? I've thought about using my heat gun with a small tube to direct the heat at only the offending area, but don't know if this would be appropriate.
If I need to carefully cut loose the rear spider from the voice coil tube to get enough voice coil to solder to, is it likiely that the coil is a bit below the spider so I won't damage it while cutting the glue joint between the spider and the tube?
