Speaker Cables For Big Horns & Tubes

If you’re looking for something affordable that is very good, maybe great considering it’s cost. Canare 4S11. Very nice sounding cable.

12g zip cord all day long on my all horn system. Anything above this is salesman BS. I could get away with 14g easily enough but I like the durability the heavier gage brings as I am not in a kind environment at times. Currently pushing a system for a 600 seat theater with 12g but since it is Klipsch based it is not over the top wattage thirsty and 14 would work just as well. runs are 15' and 24' typical to left and right channels.

Only advice worth anything is from a person with the SAME amp as you .
Speakers can only play what amp sends them . The amp is adjusting to the wire not other way around.
And to tube or SS pre-amp .

+1 for Tempo Electric simple solid silver conductor cables.  I use between my Coincident Franky Mk-II 300B's to 104dB horns.  Excellent combination and very affordable < $400. 

" Sure. Use 12 gauge OFC cables. The cost should be about 50 cents a foot... "
  100% correct. If it makes you feel better to spend gobs of cash and slurp up bad advice spend many thousands and have at it. Before you do though conduct a true blind test with what you are considering against 12g zip cord and see for yourself.
  " The amp is adjusting to the wire not other way around. "  Curious to know how an amp does this. Please be specific in your explanation of how this occurs.
