Adding an extra 1ft to premium speaker cables

Thanks for the assistance everyone. So here's the real moral of the story. How could any high quality speaker cable at any price maintain its integrity unless it were connected directly to the internal crossover or source? Almost every speaker is going to have an additional foot of internal cable or wire connecting the crossover to the internal speaker terminals that the end-user doesn't see. Psychologically the listener doesn't see this and so they make up their mind that the cables made some change to the sound. My speakers had some 14 gauge copper wire inside the cabinet, so why would any higher quality speaker cable make any difference? In essence, every speaker has an extra foot of wire that isn't going to be the same as the cables you bought. It would only be as good as the weakest link, wouldn't it?  

Audio neurosis! In the old days everyone used zip cord and nobody complained. Just add a foot or two of zip cord. Problem solved!

Put the good cables next to the speakers make sure they are bothe solid core, or both strand. It works for me.No don’t use zip cord. No disrespect to Jason.

I generally just use some 14 gauge copper wire and it works fine. I think audioholics did the best review on fancy cables ever.

Just finished my kappa 9 infinities  took apart looked like someone used cca in there.replaced the crossover and internal wire with 10 awg ofc.replaced the 2 woofers and it sounds great oak cabs. I think if you solder good wire on it won't hurt as an extension. I built a speaker cable out of 4 awg wire ofc and they sound great.i think my cardas gold reference is 4 awg. Enjoy the experiments and the music.
