Silver Wire

Understood. You are providing good info for the OP to use and decide on his own. Always worthwhile to do so in my opinion. But I think there needs to be a bit more detail wrt the 12 gauge experiment, in particular the size and shape of the wire and quality of the connection. You did write " I wasn't too thrilled about using the disconnects" but you didn't explain. Not a big deal, but the OP should know quite a bit more before putting that information to use. My opinion.

Anyhow, good posts. I am also considering re-wiring everything I can if I think inductance in particular can be lowered significantly in any of my runs (inside or out of components). But let's be clear on something ... it wasn't my logic being stated in my post. Though I'd love to take credit for it, I believe Misters Faraday, Oersted, Ampere and Henry (to name a few) were a little more influential toward that end.

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. 

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