Length of speaker cables

Hi bob

At a time you believe in what you hear, I am a guy that do engineering and science. There is a way to calculate a cable’s thickness using DF and length. So I just did.

We are way beyond the acknowledgement that speaker cables do effect sound. The only problem is that you do not whay and what to do to maximize it. I do!

Do AQ cables or William cables do?
I’m sure they don’t. Even the big names have no idea what they are doing. Trust me on that.

The nice thing is, that if you would like to improve that result, let’s say by adding thickness to the cable, beyond that figure I calculated, there will be no improvement in sound!
6 ft is for a short speaker cable for a stereo amp. Not for two monoblocks.
If you went for monoblocks, spending the money and space, take advantage of it. Make your speaker cables as short as you can.
That’s the right and best way to do it.

@b4icu,
Yes, science can help determine things, but one issue is what is being measured and how it relates to human hearing. - The latter being a variable that has no one set status, as each individual has different hearing abilities. This alone renders any scientific interpretation moot.
Add to this that even though your engineering and science measurements relate to something measurable (say electrical conductivity), it has no relation to sound quality.
And, if you are serious about scientific and engineering, then why not put them to the test? I would be interested in your results.

As audio signals are AC and hence impacted by impedance and not simple resistance, I am not seeing the technical merit nor the evidence of engineering or science of using a simple DC value for dissipation factor to determine a cable. It also only considers the source impedance but not the load impedance which are equally important in energy transfer.


If someone would like to post their reasoning so that others could analyse that would be beneficial.

Mr.  dannad
I see no particular reason why would you argue over things that you never had tried, but only critic. This is beyond understanding.
Your say about AC and Impedance are all wrong! Do homework and see: 
Wikipedia is explaining DF as: (https://en.wikipedia.org/wiki/Damping_factor)
"damping factor gives the ratio of the rated impedance of the loudspeaker to the source impedance. Only the resistive part of the loudspeaker impedance is used. The amplifier output impedance is also assumed to be totally resistive. The source impedance (that seen by the loudspeaker) includes the connecting cable impedance."

You assume that the "load impedance is equally important".
I say that the load impedance is insignificant in my analysis.
Even though, they are called "Speaker Cables", they are part of the Amp's output stage and the load.
Look at the Wikipedia / DF again. It is specifically says so.

On my side I can say that my calculations been proved many times to be accurate and be the best cable for the system. I also checked that adding thickness above that value is insignificant!
It sounds the same as the calculated thickness. 

However, all others: you, the big cable brands down to the last of them - have no idea what cable you need for your system.
That goes down to the sals guys, that spread BS with a shovel.
As you can see on my recommendation of the #8 AWG cable, it is not reaching US $50. For that money you mostly buy nothing from a big cable brand. At the time that nothing will sound better than the $50 cable at this particular system.

Do you really think and recommend to use a copper wire between your Amp and speaker as the sound tweaker (Equalizer)?
I'm sorry if your taste buds would like better the sound of a poor cable over a good one.
I've seen the fenomena.
I was involved in a demo that the guy had some "MID" fetish. He loved his mid. As the #0 AWG cable was connected, all the sudden a deep rich bass stepped in. Like a good sub was added.
He said that the #0 AWG cable killed his mid!
What it did, is only enhanced the lows. The sound was clear and dynamic. Resolution was better. But he loved the mids and nothing more. From the levels of volume he liked to listen, I think he had a survivor hearing problem. But why do a calculation or a measurement, if that condition (no common sense) is the judge?
