[QUOTE="Art Welter, post: 73470, member: 52"] Re: What is the audible result of damping? The series resistance of 100 feet of 18 AWG (200 feet total) is 1.277 ohms. Not significant regarding power loss, and makes no difference whatsoever "wrt crossover filters" used in a passive crossover speaker. I agree frequency response is important, but series resistance attenuates, simply making a speaker quieter, not changing the frequency response. The reduction in damping factor 1.27 ohms of speaker wire in series causes an amp with a damping factor of 500 to have only a damping factor of 6.2 at the speaker. An argument for reasonable sized cable. A damping factor of 6.2 sounds bad in comparison to one of 20 or more, put 100 feet of 18 gauge on one speaker, and 10 feet of 12 gauge on another, and you will hear a difference with music (assuming your hearing is in the normal range;^) ) though a SPL meter (or RTA) would show perhaps a 1/4 dB difference.
