Coiling is fine. It only adds inductance in the common mode, the signal is differential.Not coil (inductance) , just lay back and forth.

The resistance versus the attenuation from it (good copper) is so slight over a 12 gauge cable that it is near zero. Like 1.588 mili Ohm per foot. Most if not all people's multimeters cannot even measure this and a very sensitive dual input Ohm meter is req'd that costs thousands for one.IMO, most differences that "true" audiophiles hear when switching cables is because resistance/impedance of different cables is different.

It's possible you had CCA (copper clad aluminum wire) or worse. CCA has about ~30% more resistance give or take. But even then the length was not that long and still should not have that much attenuation to cause a obvious volume difference. I never buy inexpensive budget speaker wire. We had some issues at the retail level selling 18 gauge that had the insulation/dielectric that would be thicker and thinner between the 2 conductors and we had some customers with shorted wire. Not good to be selling such stupidity. So we tossed those rolls in the garbage and stopped selling it. It was quality 16G & 12G after that.I was using no name speaker wire, so probably it wasn't best copper in the world. On the other hand, cables shouldn't matter, most of us will agree.
If so, where the difference in volume came from in my case ?
Thanks. I heard you guys like numbersWelcome to ASR by the way @ebslo
Hmmm.Once I cabled my room, and because of the room configuration one of the speaker cables was 4 times longer...left speaker 8 meters, right 2 meters.
Left speaker was obviously quieter, therefore music was completely "off centre". Initially, I thought something went wrong with the speaker, but when I exchanged speakers, the other one became quieter. Then I realized different cables lengths = different resistance.
Hmmm.
My CT system (5.1) has 12ga. speaker cables and they were custom-cut and terminated by the manufacturer. Because the electronics are in one corner of the room, the lengths vary from 2M (Left Front) to 12M (Right Surround). However, there are no differences (audible or measurable) in level among the identical speakers (LF, C, RF or LS, RS). Front vs. rear are different speakers so there are real differences there.
You should view this very recent video from the electrical engineer at AudioholicsIf it wasn't because of wires, then only remaining cause could be temporary glitch in left/right balance in the receiver.
Now I'm completely confused and intrigued...I will definitely check it again.
