Hi rpw,
I'm having a hard time describing a rather simple thing. Let me try again just so everything is transparent.
I have two pieces that are 3.8 m long. They comprise a single positive/negative run that could go to one speaker about 12.5 ft away.
If you cut these two pieces in half, you'd then have a matched set of speaker wires for a system, each pair being about 6 ft in length. That will work on many systems with the components centered between the speakers.
I'm selling it by the linear meter, so if you want what I listed as the two 3.8 meter pieces, they would be calculated 2 times 3.8 times $13 = $98.80
Ditto on the longer piece I have.
You can PM me if still interested in some combo of what I have. Thanks.
