Repair of dome tweeter

[surfatwork]

Just posting this in case it helps anyone. This is a Diy repair of a dome tweeter in a fairly aged speaker - the drivers are custom made and hence unobtainium.

Initially I thought the tweeter coil had blown, but more careful checking revealed that the coil was actually fine. The delicate connecting wires had corroded. So the Diy was to replace these connecting wires.

You can see the old wires in the first Pic. The blue and red wires in that same pic are salvaged from my junk box. Straight forward work, but delicate and fiddly. Needs care not to crush the dome, or to damage the coil.

So next time, partly working speakers may be worth checking out before discarding them.

Recently I came across this video on Youtube

Is it right to use silicone spray on speaker drivers' rubber surround?
If yes, what are the preferred brands available in India?
I find many brands on Amazon India.

No restriction to start new threads. Infact will get more exposure amongst out of place clutter of threads. Give proper title to thread as it may help others.

The spray would change the properties of compliance of driver surrounds. Probably the sensitivity would decrease. How much is unpredictable.

Silicone spray only provides surface protection. So if used before the rubber hardens, it may help extend the life of the rubber. But if the rubber has already hardened and become brittle, it is not likely to help.
