Increasing shunt capacitance will attenuate higher frequencies, but as you saw in the charts, the capacitor on the Zobel has a pretty wide tolerance of values. You have to make fairly large changes in the capacitance value to make a difference. The larger the capacitor is made, the more the Zobel begins to act like a pure resistor in shunt across the speaker.
