Wife stepping on speaker wire


I'm looking for a heavy duty, thick pair of speaker wire that she can see from a great distance. I have never come across a person that has no regard where she plops down her size 8's. Any suggestions would be a god send.

Tbg, SC= Speaker Cable.

Thanks for the info, never heard the one per cable before.
What make do you use?
Suspending cables and cords from fishing line from eye hooks in the ceiling works for me. Kills two birds with one stone. It's what the pros do.
Schubert, Right-way Audio marketed these some years ago. They look like insulators that you see on telephone poles, but not made of glass. I cannot find any such firm now. I bought 24 of them.

I had never heard of one per cable either until I was urged to try it by the Right-way owner. Sometimes I just cannot achieve this but consistently I have found it best.

Geoffkait, I have never tried fishing cords from ceiling eye hooks. Perhaps this is because my ceilings are 11 feet up and also because it looks so crappy. I have used cord from tripods left over from my photography days. For some reason, perhaps vibrations, I prefer isolators.
