Further, a Zobel network in audio systems is usually implemented at the amplifier output terminals, rather than at the speakers, although I suppose it could be done either way, but the calculation would be different, because the speaker wires have resistance, capacitance, inductance that has to be accounted for. You also have to know a lot about the reactances of the drivers in the speaker. I would not know how to do the math without doing a lot of reading beforehand.I do use an RC series filter at my speaker terminals based on the Walker Audio HD Links, which is, according to Al Sekala, a 10R or 100R resistor and a .01uF capacitor. This has virtually no benefit for impedance matching or frequency response flattening at audio frequencies; it's merely a filter for RF. (As I have said probably ad nauseam, it is not a Zobel network.) Try it yourself; it's easy to build one, but you need to use a capacitor that is good at RF frequencies and likewise for the resistor.
