I'm just getting into speaker measurement and constructed a little microphone rig with a Panasonic WM-61A and a simple 2.2K resistor and 1uF cap and a supply voltage. This is fed into my line-in of my mac.
I have managed to get frequency response graphs with the software, but they always peak at about -10dB.
I've watched a few videos on using Fuzzmeasure, but they always seem to have a graph that peaks at around 0dB.
How can you actually carry out a proper SPL frequency response, like the ones you see in the driver datasheet?
On a plus note, I did manage to get an impedance graph using the loop back technique with a 1K resistor between in and out. Measuring a 10ohm load first and then the actual driver
