Its very common to use two different cables for highs and lows... ( Silver top and Copper for bottom ) Its nice if you stay with the same manufacturer,which might help in matching..As far as lengths as long as they are not extremely different in length I wouldn't be too consurned..However must just get them both the same length and deal with the extra cable length for the shorter run...
Speaker cable length L/R differential
I know this has been discussed before some time ago, but I was wondering if more recent opinions can be posted regarding whether or not to use different lengths of cable for left and right speakers respectively. And for that matter, whether one might attempt to use different lengths between top and bottom of a biwired or even biamped setup. Some local boutique audio shops differ and insist that it doesn't make a difference. If it does, to what extent, and to what limitations on say percentage of difference.
