Almarg, do you believe that is harmful, for instance to use a copper cable such as Cardas Golden Cross on high frequencies and Clear Day, silver, on low frequencies?
Not necessarily, Denis. Consider, for example, that some highly regarded manufacturers of amplifiers and speakers suggest that in situations where tube amps are being used it may sometimes be desirable to use different amplifier taps for the highs and the lows. That certainly figures to have more of an effect on differences between the highs and the lows than the type of metal that is used in the speaker cables. Different amplifier taps have significantly different signal voltages on them.
That said, if the impedance of the low frequency section of the speaker is low, and/or if the length of the cable is long, personally I'd be hesitant to use a silver cable such as Clear Day for that connection, at least in anything less than the double shotgun version. The relatively narrow gauge of the lesser versions, and of some of the silver speaker cables from other manufacturers, IMO can result in a high enough resistance to be a concern under those circumstances. The opinions of others about that may differ in some cases, but given that the resistance of copper is only about 6 to 8% higher than the resistance of silver, for equal gauge and length, if those other opinions are correct there would seem to be no need for the very heavy gauges of the copper cables many audiophiles use. (Increasing the diameter of a conductor by just one gauge size reduces its resistance by about 20%).
