I'm looking at the spec sheet for the popular Panasonic WM-61A, and their hookup schematic includes a 2.2K resistor powering the mic from +Vs, and a 1uF capacitor on the output.
I also found a schematic of a preamp that seems well regarded. Image attached.
So if the WM-61A is attached to this schematic, including the aforementioned 2.2K resistor and the 1uF capacitor, isn't there a high pass filter (C1+R3) now in place right before the op-amp?
Does the very flat response curve of the WM-61A take into account that this high pass filter will be in place? I modelled this in Ltspice and get -6db @ 20hz.
