Or measure it. Been there, done that. Please see http://www.pcavtech.com/pwramp/ , lower 2/3 of page. Really, if you measure it someone might learn what is significant, and what is not. In general, we already know. Because audio frequencies are relatively low and the amp-speaker interface is by design not impedance-matched, the most important thing about real-world speaker cable is resistance, and to a far lesser degree in almost every case, inductance. |

om (Stewart Pinkerton) wrote in message While true, this is irrelevant to the fact that lumped theory is perfectly adequate for audio frequencies in domestic situations. Yes, I agree that lumped constant models are perfectly adaquate for audio frequencies, if one doesn't have the software necessary for modeling a true transmission line. BTW, have *you* ever tried modeling a *real* speaker cable using lumped constants? I'm curious to see what you used as a lumped constant model. Please show us a model of 100 ft of standard (Home Depot), 12 gage cable (terminated by an ideal 8 Ohm load). Please see http://www.pcavtech.com/pwramp/, lower 2/3 of the page. |

m Kevin McMurtrie wrote in message ... It's all irrelevant for audio frequencies and normal lengths of wire. Having the two conductors side by side is perfectly good. Just don't split the wires and route them to the speaker along opposite walls. Just curious, but what *would* happen if you did that? Higher series inductance. |
