    Maximum seaker cable lengths..

    Post by Ernstmach on Sun Sep 04, 2016 9:56 am

    I'm going to do some renovation in my listening room and I'm considering gear layout to maximize speaker location.
    I'm running MKIII's to my Focal 948 speakers. Plenty of power for these speakers. Cable run maybe at most 25'. If I were to run them straight it would be less but I don't want guests tripping over cables.
    The cables I'm using now are 12'.
    My room is 12X18X8.

    Any thoughts, advice, other considerations?
    Thanks!

    If I were you I would set the amps next to the speakers with just a few feet of speaker cable and use longer interconnects which can run along the corners back to your preamp.

    12gauge, fine-stranded THHN, spun in a drill until loosely spiraled. Good for 40' pretry much any amp, any speakers.

    I believe you can run up to 50 feet (per side) of 10-gauge speaker cable with no increase in resistance, or impedance issues.

    Peter, just for education's sake, why spiraled?

    Short as possible is good general rule.

    Speaker impeance, distance and wire gauge are the variables, there is a formula if you want to do math.
    Here is a link to a chart for rough guideline if you don't.

    Reduces already negligible induction.

    Peter W., thanks for that chart. I notice that Yamaha cautions against any runs over 50 feet, regardless of gauge. So I guess obsessing over whether an 8-foot or a 10-foot run is best is really picking the pepper out of the rat-shite.

    That would be Fly material.... Rat material is too easy!
