Cartridge Resonance Calculator
Every arm and cartridge pair forms a resonant system: the cartridge suspension is the spring, the arm and cartridge are the mass. Pick your arm and your cartridge from the lists and their figures come with them, so matching a pair does not start with hunting down your arm's effective mass. Enter the numbers by hand instead if yours are not listed.
Treat the result as a guide rather than a verdict. Published compliance figures are measured differently between makers, and suspensions drift with age. A pairing a little outside the band can still track well; the calculation tells you where to look if it doesn't.
Who makes these
Bool Audio is a father and son making hi-fi components in a small UK workshop. We build the Clear Wave unipivot tonearm and the Clear Wave 2.0 tonearm cable, both for the Linn LP12. These calculators began as our own bench arithmetic. They are free to use, there is nothing to install, and they take no view on which cartridge or tonearm you should own.
