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

Mr. kosst_amojan

There is nothing in your observation to disapprove nor approve anything. 

I'll use Confucius say:

The one who asks a question, may look fool for a few minutes. The one who don't, will remain fool for the rest of his lives.

This has got to be one of the dumbest threads ever created around the subject of cables.

I read through every single post, holding back laughing and crying the entire time. The OP of this thread doesn’t have the first idea about the science behind the transmission of amplified sound. Instead of wasting my time explaining to you all what is wrong with these posts... you can start down the road of real understanding by reading this-

I believe Transparent Cables does just what you ask - they take all of your equipment parameters and calculate the "perfect" cable specs for you. See? Your search is over.

+1 morg111! What the heck b4icu is spouting is NOT SCIENCE!

Example (one of many): "Unfortunately, most speaker cables are of 14-12 AWG and with some length from 8' to 24'. For the length, by increase the length from 8' to 16', in order to keep the same resistance of a cable, the cable's cross-section needs to double. For 24' length it needs to triple and so on."

No. That is not correct.

And the cable does not contribute to the Damping Factor (DF).

Resistance in an 8 ft length of 12 AWG copper wire is INSIGNIFICANT!

How old are you?
Cables calculate? If they could also cook we could merry them.
