so its gonna look something like this: ?
Yahhh....
Always try to keep capacitor on positive... Many people on other forums have reported electrical losses..
That's the only issue with putting resistor first, capacitor after that. They report that, in Zobel also, if not followed in order, the capacitor tends to add sound tone... Another engineer quoted that it was electrical loss and nothing like adding tone..
I still did not see any difference on BA and headphone dynamics drivers, but there was a significant difference in sound with loudspeaker in treble region(front and back loaded horn speaker diy)
Treble seemed damped.
One guy gave me example, that in ideal conditions, this doesn't happen and small driver like BA dont suck so much volt or ampere, so capacitor ESR and tolerance error doesn't effect that much.
In speaker, those small % error becomes huge and resistor electrical loss parameters comes into play due to Musical signal or Rapid changing signal(we call it breakdown)
If C is used first, you make the resistor get less load...
In ideal situation or less voltage situation, it doesnt do anything but better follow conventional method.
And conventional method also have an issue
Its ESR and ESL
Keep them in minimum..
losses due to ESR will inhibit a capacitor’s ability to quickly source or sink charge. At the input, increasing ESR increases high frequency noise across the capacitor, decreasing filtering effectiveness. At the output, higher ESR causes more ripple, influencing stability of the control loop.
ESR is particularly important in applications with low duty-cycle, high-frequency current pulses.
the ripple voltage due to the ESR will be greater than expected based on capacitance alone, although the negative correlation of ESR
So that means, if a High ESR is used, first of all, the zobel is wrong. Secondly its impedance will behave randomly (even though still flat) according to the music.
Tested it in labs here
Will post observations when I go to my old office
