Silver Wire

I expect to have to learn to solder at higher temperatures. And to use heat sinking near heat-sensitive components on the crossover.

I'd expect the silver wire to have less resistance than the copper, but measuring first is not a bad idea.  

If I decide to build my crossovers from scratch, with new components, then I might use the silver stuff there, too. 

Thanks for the info, guys. I plan to solder everything inside the boxes - I can't see using expensive plugs and sockets (which might come loose anyway) and I certainly won't use cheap spade lugs, either. So soldering seems the only way to go. 

I understand that the normal method with interconnects, and components too, is to change one thing out at a time with extended listening sessions in between, but with internal speaker wiring, I think I'll try it all at once. I was going to use a heavier gauge for the woofers, especially if I go the bi-amping route, but now I think I'll use the same gauge for everything. The only question I have now is what kind of wire. For now, I'll leave the crossovers in copper. It's a lot of work to re-do them.
