These values are recommended as a good starting place for an 8ohm speaker, you can mess with the cap value to roll more or less highs off. Here is a Zobel calculator. http://www.carstereo.com/help/Articles.cfm?id=36

So I was playing with a Zobel filter and thought this could work as a way to de-fizz the AB III at higher attenuation levels. So I built a quick in-line box to test it with very good results! Here is the proposed layout, the values are for an 8 ohm load and it should handle up to 100Watts. Let me kn...

Where should the adjustable lug that is connected to the 8R 25W resistor(circled in red) be positioned? (Measured in ohms.)

Does it mater if the switch is shorting or Non-shorting?
