    Bi-wiring. Bunkum or for real?

    Post by deepee99 on Mon Oct 23, 2017 2:45 pm

    I don't understand the eccentricities of electrons sufficiently to grasp why running two parallel identical cables from the same outputs of a power amp into the same two posts at the speakers ought to make a bit of difference. Yet it made an audible improvement with my old Vandersteens but don't do a thing for the Tylers. Any thoughts?

    There are any number of reasons - but the most likely that comes to mind is a function in four variables, of current, volume, speaker efficiency and distance.

    Speaker wire is rated for a basic amount of current - more than that and some of the energy goes up as heat. Additional conductivity reduces those losses. Which relates to the efficiency of the speaker - if, at a given volume, the capacity of the wire is not taxed, all is well. However, a different speaker will have different power demands - and there you are. Or, if distance A is 10 feet and distance B is 25 feet - as above with wire resistance added. Cutting to the chase - FAT cables good. THIN cables bad. Four legs good, two legs better (if the legs are fat enough). Twice the diameter = four times the conductor area. But - a copper pipe is very nearly almost as good as a solid rod of the same diameter, and very much better than a solid rod of the same mass. For the same reason, stranded wire is better than solid wire of the same mass.

    I was running 10-g solid wire in both instances to the Vandies; standard 8-foot runs. A single run should have been adequate to the task.
    I am running stranded silver to the Tylers. Maybe there's the variable I've been looking for. Not so much the silver as the stranded.
