What is the outer diameter of the insulation?

When separated, a single strand is .165 in. in diameter and together it measures .165 in. by .345 in.

It says 99% copper but looks like less conductive and cheaper copper clad aluminum. . Which is it?

I assumed it was as advertised: 99% copper. There are different grades of copper, so conductivity may well vary, but like you, I was looking for a step up from copper clad aluminum. Don't know for sure if I got it, but the cable is thick and my system sounds good with it.

Probably china. The wire feels very high quality. It’s soft and flexible, and I got fuller richer sound out my home theater after I rewired with this.

So are we getting 50ft of each =100ft or 100ft of each =200ft?

It's One 100ft spool of speaker wire.
