+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!
