"I usually paint the windings with some thinned down epoxy, or some wire varnish"

I thought I read that they were vacuum impregnated, that isn't enough?

"I got an LCR meter, and I'm gonna use it!"

Well, you're ahead of me, I don't. I can measure C but have to use a Fn generator and scope to measure Fr and Q and L. Maybe I should spring for one heck, even in Jr-High half a century ago I had an LCR bridge!

As you can tell by this question I'm only THINKING about playing with speakers, but why use foil inductors at all?

Thanks, Rick
