Nevertheless in a 32 Ohms speaker case, you should use a cheaper and
smaller solution : R1 = 82 Ohm et C2 = 4.7µF (ceramic)
The gain of SPK outputs is internally adjusted and can be tuned using an AT
command.

(*) analog gain : might not be significant
(**) control of the receive gain by AT commands (for WISMO Quik Q24x6
Series driven by AT commands)
Recommended characteristics for the speaker:
Type : 10 mW, electro-magnetic
Impedance : 32 to 150 Ω
Sensitivity : 110 dB SPL min. (0dB = 20µPa)
Frequency response compatible with the GSM specifications
