In Reply to: RE: What kind of hookup wire does Magnepan use in Crossover, stranded copper or stranded aluminum? posted by Roger Gustavsson on September 21, 2012 at 07:36:26:
I used to have trouble with the jumpers that connected the panels on my 1-D's. They'd get crackly. Of course, I used to move the panels around so they flexed, not to mention that in those days a lot of people smoked.
Flexing shouldn't be a problem inside the speakers but as you say galvanic reactions could occur where dissimilar metals are in contact, particularly in humid and salt air environments. Still, crimp connections seem to be reliable even where dissimilar metals are involved as they almost always are. I assume that this is because the crimps are gas tight, and keep out moisture -- no electrolyte, no reaction.
That wouldn't be true of the slip-on pressure connectors, but those would use the same plating. I imagine they're tight enough to prevent surface oxidation too, but once removed, it seems to me that they should be cleaned with Deoxit since they won't seat again in exactly the same place. I've often seen clean and oxidized areas in disassembled connectors, depending on where they mated.
Crimp connections aside, I always try to avoid mating dissimilar metals. I used to use Cramolin when I did, as far as I know that isn't available anymore but there's another corrosion prevention product whose name I can't remember that does the same thing.
