- This might be caused by a wrong setting within REW or that mic may just not have much response below 100hz ( not that unusual for a voice mic ).
Alan I agree with Earl on this after closer inspection of that resistor it does appear to be 6.8K.. And also reiterate that your sweeps aren't going low enough and the reason for the lack of bass in your response sweeps..

FWIW I use with my laptop.

Fast Track Pro soundcard
Behringer Mic and Mic cable 25'
Holm Impulse software
Jam Stands telescoping boom stand.

IMO Holm Impulse is much easier to use for beginners..
