RE: Tweeter Wire is better than QR?

What I'm thinking is that if you follow the path of the original aluminum woofer wire with aluminum foil of the proper thickness, you should be able to reproduce both the original mass (for the right resonance point) and the original impedance (for the crossover and to maintain efficiency) with the desired trace width (determined by I don't know what voodoo, but the 1.7 woofer might serve as a guide). Then all you have to do is cut the aluminum foil, I believe it can be cut by hand and glued with the spray adhesive and then Milloxaned. The only diff with the tweeter would be no Milloxane (I think).

I believe that this is the way they do it, apparently it doesn't make economic sense to etch the aluminum coil on a large diaphragm. I'm thinking that you run the strip up, then flip it over itself and run it over, then flip it over itself again and run it back down. I'd have to take another look at the MMG tweeter to see whether they do that, or cut the pattern out of a sheet.

Then, you could go in business selling foil upgrade kits to the rest of us!
