If a speaker cable added 1 - 2 ohms of resistance would that be?


A good thing.

A bad thing.

A very good thing.

A very bad thing.

 

We are talking in generalities here. I am sure there are also exceptions.

You can measure, but the figures I posted are accurate. They appear to sell 4-10 feet versions. The figures I posted are for the total loop (both wires).

They are not buying them because of the resistance because they don't even know it is there. They are liking it because of the resistance. It would swamp every other property of the cable. I think Eric is right, it is a tone control that cannot be changed. If the most common change is to raise the mid-range, is that not normally a change that people prefer at first? I don't know if that would be a long term preference.

 

That would make your solid state amplifier sound like tube amplifier. It will eliminate the effects of dynamic damping, possibly screw with your speakers cross over (no in a damaging way) depending on the speaker

I went to their website because the construction looked really interesting. It piqued my curiosity. When I read their marketing information, things were not adding up for me. My background is solid state physics and material sciences for semiconductors and batteries so I live this stuff (materials, not cables). It did not take long to narrow it down to what the base properties must be, what the likely material was, and important, that the material would be high resistance. That resistance is missing from the marketing material.

 

Of course, @crustycoot is correct that a couple of ohms of speaker-cable resistance will degrade the realized damping factor considerably. The nominal damping factor is usually computed

DF = 8 / Z

where 8 is the assumed impedance of the loudspeaker, and Z the output impedance of the amplifier.

So you would achieve a nominal damping factor of 200 (not out of the ballpark for a SS amp) with the output impedance of the amp being 0.04 ohms. If you add 10 feet of Belden 5T00UP, you’d add another 0.01 ohms, and the effective DF would be 160. If you added 2 ohms of cable resistance, the effective DF would be about 4.

Some prefer an underdamped sound.

P.S. I am prone to typos and simple math errors, so if I’ve made any, please point them out and correct them.
