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

You really need to make a 4 wire measurenent to accurateley measure resistance especially at this low value.  And as I understand the Inductance of the wire makes more diff than the resistance...

@pmerendino,

If these are 1-2 ohms, a standard good quality meter should get you close enough. Not perfect, but close enough.

For inductance, back of envelope assuming 2 inch average spacing would be 400nH/foot. At 6" that is 1.1uH / foot. That's just first order equations. I could simulate it in FEA but hardly seems worth it. If my math is right that’s about 0.7 ohms impedance but at 20KHz and I have not been able to hear there for a long time. Back to my stereophile phase and impedance charts, the impact would depend on the speaker. It does not seem like a good design to allow the inductance to be so variable.

If these are 1-2 ohms, a standard good quality meter should get you close enough. Not perfect, but close enough.

No, you really need to make a four-wire measurement.  1 or 2 ohm is too much for a 8ft cable.

If the cable is 1.7 or 1.9 ohms does it really matter? The point is there is a big resistance. Even if it was 1.0 or 1.2 ... is close enough. For 8 ft it will be about 1.5.

DC resistance will affect the bass the most. It will make the sound lacking dynamic since the amp won’t be able to drive the woofer as hard.

An 8ft cable should have no more than .1 or .2 ohm of DC resistance.
