Speaker wire impedance? Speaker impedance?

While on the subject of speaker cables.... Do not neatly coil excess speaker (or interconnects) wire, this is, in effect, making a coil, AKA "choke", and will definitely affect impedance. If you have excess wire it is better to have that extra wire "chaotic" crossing it self at close to right angles. Recent research is showing the life on the air side of the insulated wire is as interesting as what takes place in the "conductor".

it's an amazing place there in the Quantum Realm. Visit often. Take only pictures. Leave only footprints.......if you can

basically you are saying that measurements I took with my meter set to ohms are probably not accurate?

@immatthewj Yes. You need a really special Ohmmeter to read the actual resistance of most speaker cables! You were far more likely reading the contact resistance of your probes and probe wires than you were the speaker cables. To read a speaker cable you need an Ohmmeter that can read differences in resistance of only 0.0001 Ohms. That's an expensive and specialized Ohmmeter that can do that!

Thank you.  I will no longer spend time trying to measure my speaker wire resistance.  

You really need a micro-ohmeter to measure such small resistances. best bet is to calculate it. if it is too high, then you need larger wire. the manual only mentioned "resistence" which is a funcion of wire gauge and length only, so the inductive portion of impedance apparently isn’t a problem for these speakers, still it should be minimized. Avoid loops, for example.

Also avoid alloy wires for speakers. Surprisingly, alloys are always higher resistance--add silver to copper and you get an alloy that is a worse conductor than either silver or copper alone.

As for your question, the impedence of the speaker is the load where power is turned into sound, the resistance (lets equiate it to impedence) of the cable is the circuit that transmits the signal to the speaker. You don’t want any of the power being disipated there.

@atmasphere and ​​​​​@carlsbad2 and @everybody else who tried to dumb this down an explain it for me--thank you.

@atmasphere and ​​​​​@carlsbad2 I now know that on a couple of levels I wouldn’t get an accurate reading--for one the meter I was using,

and also: the fact that I was taking my reading from the amplifier post (with cables hooked up) to speaker wire post of speaker (with cables hooked up, and then again from amp post to the other end with cables NOT hooked up on speaker end).

Either way, that probably screwed up the measurement I was TRYING to take, right?

So last question: the actual resistance was probably way lower that the 0.07 and 0.05 that I THOUGHT that I was reading?

And as an aside, my speaker cables (Kimber, and I THINK I remember that they they are 8TC and 4TC) probably are longer than what would be considered ideal.
