Think of it this way.If cross talk in speaker wires in conduit was an issue, would it not be MORE of an issue in multi core speaker cable? Where the conductors are forced to be very close to each other?I have never heard of anybody complaining about crosstalk in a NL8 or socopex speaker cable.
Twisting a speaker wire pair has two advantages:a] Reduces the self-inductance of the pair. High self-inductance on a long run can reduce treble response.b] In rare cases, it can inhibit the speaker pair from acting as a interference antenna.
But the longer length will add capacitance-which will also reduce the HF.
But the longer length will add capacitance-which will also reduce the HF.I am not sure how much each would add or reduce to affect the overall response.Of course it will greatly depend on a lot of factors, the twist ratio, the impedance of the load, the length of the run, the size of the insulation of the wire, the ga of the wire and so forth.There is no "easy simple" answer, unless you know all of the details involved. And even then you have to do some calculations in order to get a usable answer.
How much shunt capacitance would make a noticeable difference in the HF response of an 8 ohm speaker? Now, I don't know what the capacitance per foot of a twisted pair of #10 THHN is but consider that the capacitance for a twisted pair of 24 ga outside plant telephone cable is .076 mfd per mile.
Notice that I said it would affect the HF.I DID NOT say how much or at what freq----------------
And neither did I. My question was rhetorical. -Hal
