What is your method for measuring T/S parameters?

I'm not sure if it's more accurate, but they do go through a calibration procedure with a high accuracy resistor.

I use precision resistors so it will be oke.

I can also measure them and then use that value.

For the added mass method, you want to use a mass that is approximately equal to the cone mass - so that the resonance frequency with added mass is approximately 0.7 times the normal resonance frequency. For diameter you want to use about half of the surround width.
