Anyone Make Budget Flat Speaker Cable?

Oh. Had you mentioned the budget in your OP, I'd have not suggested Goertz.

For rear channels almost any old wire is good enough. IMO. The Radio Shack should work out perfect.

Partsexpress has a few choices. Around .50 ft or less if you buy bulk. Good quality.

DNM reson is not quite budget but not too costly and meets your specs.

Elizabeth: I agree. I'm using AR copper pair (glorified lamp cord) but too bulky under rug.

It's hard to believe Nordost doesn't make resonably priced wire for the "prosperity challenged" audiophile.

Listening to Blu-Ray Start-Trek, the AR wire passed high-frequency signals I'm surprised I can still hear.
I WAS using KEF 201 Ref for surrounds (love those super tweeters!).
