Hello
First Thanks for Development of such a useful software.
I need help with measuring Impedance, and the problem is very very small results by measuring, please read the problem description:
Hope someone can help me.
I try using REW to measure Thiele Small Parameters using Added Mass Method.
To do that, I use REW V5.20.13, a PC (using front panel MIC and Headphone interface).
As the first step by reading help file, I started by Measuring Speaker Driver Impedance and I made a jig as following picture (same as suggested in Help File):
The 2nd Step, I did Calibration as the Following settings:
and I did all 3 steps of Calibration process.
After I measure a known speaker, the results on Y-Axis looks so weird, the Impedance show about 20 mOhms to 50 mOhms, that is so low.
(mdat file is attached)
The Driver Impedance graph from manufacturer shown as below:
