Varying length of speaker wire a no-no?

    I only have two main speakers set up (front right and front left). The way I have my A/V components and speakers situated called for me to cut two different lengths of speaker wire. One wire is roughly 10 feet long and the other is about half that. I'm not sure of the gauge of the wire but it is your typical size found just about anywhere. My question is did I do right in cutting the wire custom length or should I have cut both wires exactly the same length regardless of the length I actually needed? The reason why I cut them at custom lengths is because I was using someones extra speaker wire and they needed some to spare.

    Will the sound be different between the two speakers or does it even matter due to the short distance between the receiver and speaker? Sometimes I think I do hear that one speaker is slightly louder than the other but I think this just might be my imagination (or a placebo-effect).

    if you do the math, it takes much much more difference in length than you are using to have a noticable effect.

    don't worry about it but sometimes cutting things too neatly curtails your ability to move things around.

    There is a thread on this at the AVSForum. It would take a large amount of wire before there would be a noticeable difference. If I remember correctly....hundreds of feet.

    Ok... Just to add to this... I set up two speakers and a stereo
    receiver and had 100 feet of wire going to one speaker and 20 feet
    going to the other (that's an 80 foot difference)... During the
    nice little demo I put together, I noticed no difference...
    However, because I had 80 feet of wire in a spool, I did seem
    to get that "inductor" effect.

    So... I guess it would probably take, umm, 300 or more feet to make
    a slight difference that no human would notice. [​IMG]

    can't get the inductor effect since the currents are going in opposite directions and cancel. but maybe a difference do to resistance!

    Yea... That's it... Resistance... I was using small cables...
    Which would explain resistance being the difference.
