RC lowpass worksIs not a good idea of using one cap parallel to the driver without resistor for low pass filter.
Only one series cap for High pass filter.
RC low pass – how it works
The output voltage Vout follows the erratic input voltage Vin delayed in time in the same jump height. This is because the changed input voltage briefly passes through the capacitor because the capacitive resistance of the capacitor builds up first. Once the capacitive reactance has reached its new value, the output voltage does not change any further.
With a sinusoidal input voltage, on the other hand, we get a weakened output voltage. The attenuation depends strongly on the frequency due to the slowly developing capacitive reactance of the capacitor. As the input frequency increases, so does the difference between the input and output voltages.
Capacitor in parallel of driver act as lowpass(as series act as highpass)
And resistor in series(to attenuate the system and change the F3 or the point of rolloff, or impedance match or impedance setting while crossing)
