Unfortunately, the effective Le and Re of the speaker's voice coil are going to change with increasing frequency. Fortunately, the Zobel circuits are not that sensitive so getting a Le and Re result at 1 kHz is good enough for sizing the Zobel. This is why there is typically a 25% factor in the rule of thumb equations for calculating the Zobel's capacitance and resistance.
