Home Audio People ! How Long Can Speaker Wire Be Before There Is Audio Quality Loss ?
I just got a new surround sound (my first)....and I want to hide all my wiring as best I can.
I may need more than the factory given wiring to do so......so I was thinking of going out and buying some speaker wire and just attaching it onto the factory wiring to extend the wire.
Will there be a significant audio quality loss ? It wont be THAT much extra wire being added on.
Thanks !
here is a good read on speaker wire size v length.
i would advise not to add on to wires.

it wont make an apreciable difference as long as you maintain precicely the same amount of wire for each channel of each left and right pair.
the signal will travel along the wire at a fixed speed and if the lengths are too lopsided then you will have the signal arriving to one speaker ahead of the other causing a phase distotion
if severe enough that could cuse the left woofer to be moving in while the right is moving out thus cancelling much of the sound and give you a hollow weak sound.
just make sure the wire you add is at least as heavy as th wire thats attached

There’s lots of factors that can attribute to audio loss or distortion, length of wire being one of them. However; unless you have a media room the size of a grand cathedral, I wouldn’t worry about wire length. Besides external influences, as far as I know, the only limiting factor that can have an effect is voltage drop. I believe that one calculation is based on length of conductor measured in feet, conductor size measured by the AWG, (American Wire Gauge) and input current. This is a good place to start when trouble shooting audio distortion since you can immediately rule out voltage drop as the problem with a simple calculation. If you’re only adding a few feet, (even up to 75ft or so) I haven’t experienced any audio loss in 10+ years. Hope this helps.

maybe at about 40 ft there would be measurable quality loss. but thats only with a machine. you wont notice any quality loss unless you have an unblieveable system.

There won’t be a very noticeable difference if there is even a difference at all.
