In Reply to: RE: "If we replaced the wire with foil that had 1/4th the mass and 4X the resistance per inch" ... posted by tom_gootee on July 2, 2011 at 13:51:32:
That's an interesting question, actually. I'm still assuming we can't parallel foil as you can the wire. So you can't forex double just the central section, as in some of the early models. But that doesn't mean you can't run more current through say the central area of the diaphragm to produce the same effect.
Anyway, as I see it, we'll be using foil with half the mass in the tweeter, so if it's the same width we just run two sections in parallel to restore the nominal 4 ohm DCR. And if we do the same in the woofer, that is, half the mass, that's a simple parallel run as well. The foil's been made available to us, so whey doesn't someone who's doing the mod just get some? Then we can measure it and find a source of the bass foil.
