Oh and to work the maths backwards the resonant frequency is equal to 159 divided by the square root of the effective mass of the arm times the compliance of the cartridge. Even so, you will only come out approximately, because of variance in compliance with frequency and static vs. dynamic compliance to name just two of the reasons.
How to measure tonearm effective mass
Some of us who use high or low compliance cartridges fret about mating them with tonearms of low or high effective mass, respectively. Most of us rely upon data supplied by some manufacturers to specify the effective mass of their tonearms, but many manufacturers do not even supply such data. Does anyone know a simple and relatively accurate method for determining effective mass? We know what "effective mass" is; we want to know how to measure it.
