FM Impedance/VAS/spreadsheet? Added Mass....I use FM 3.1.1. I will begin making impedance measurements. I understand there is a workaround using a spreadsheet which will allow the calculation of VAS from "added mass" measurements. I would like to do this because I have some unknown woofers and I want to generate as complete a set of TS parameters as is possible. Anyone doing this and can you point me to this spreadsheet?-

Clarifying what I said above, I think I windowed the impulse, effectively gating out the reflection. I'm not sure if I got the window right. though. -

Thanks, Chris. I did that, and I am taking a guess this is the reflection, windowed, what do you think? I am measuring at 1 meter and I am getting a resolution of 127.83 Hz. Am I doing this right?

windowingAttempting to set window in Fuzzmeasure for semi anechoic response. Using the impulse graph, I'm looking for that first echo, but not sure where it is. I zoom into the vertical, but it's still not obvious to me. Any tips? I'm generally measuring speaker systems at 1 meter.
