No one actually knows how to lculate what speaker cable they need


It goes back to cable manufaturars, mostly provide no relevant data! to sales and the users. None will answer this!
Whay do you think that you own now the optimal cable to your setup?
I think I've figured it out.

Thanks mitch, secret revealed!
Well, what do you know, used the formula and my speaker cables are just a few inches longer than optimum. All done by ear and the formula verifies it.

According to that calculator, I need 0 AWG to have the final (calculated) damping factor about the same as what amplifier instructions say it is. Not much of a revelation. Didn't we already conclude that it all comes down to 0 AWG? Making the cable 10 (ten) times longer does bring it down some but 15 meters per channel would mean 30 meters between speakers and that must be a rare occasion in real life.

It is nice, but…Not yet! 

1.       This is not a formula to provide the gauge out of length and DF.

2.       You need to feed the wire gauge till you tune out a close DF to the amp's DF.

How close is close enough?

3.       This calculator will accept wire gauge only up to 0 AWG. Some longer cables or higher DF are out of range!

What is the formula when a 0 AWG at some DF or length doesn't get the results?

4.       The speaker's impedance, should not impact the amp's DF. So why going from 8 Ohms to 4 Ohms changes the calculated DF figure?

 

Even if this would be the solution (and it is not), how many cable makers use (or used) such a calculator, to figure out what is the required cable to your setup? NONE!

 

Let's look back and see what we had here:

 

1.       People claimed that the speaker cable should be chosen by listening and not by calculation. If it comes through Google or the web, than it is O.k. If I say it…No!

Do you know how much clutter is on the web? Not all on the web is a holy bible. Even the bible was written by man.

2.       All the sudden, DF is a factor to choose a speaker cable! Till my thread no one connected between the two?

3.       All the sudden a thick cable (4 to 000 AWG or more) seems to be O.k.

Till my thread you were thinking it is good only for jump start cables!

4.       None of you went into the understanding how and why this additional resistance of a cable is effecting your sound. Or giving it a solid ratio between a bad cable and a good cable. Till now the difference was told by a sales man who pushed you the cable he would benefit from most, not the one your system really needs.

5.       Going back to my say, that most of you are having the wrong cable connected in your system!

6.       How many cable manufacturers you know, that offer cables of 4 AWG and thicker? What kind of money do they charge for it?

7.       For the naggers, you changed your skin in a second, as a salamander camouflage, even thou nothing really changed in my claim. Is that shows what kind of people you are?
