A Wally Malewicz inspired "three-way" tonearm/cartridge resonance calculator


Warning!
Assumes that the quoted cartridge compliance references 10Hz.
[Often (sadly) not published by manufacturers]


"There is one snag about it. The manufacturers of cartridges do not always state a useful value for C(ompliance). (It should be started at 10 Hz). Figures of C coming from Japan usually are measured at 100 Hz, so they should be multiplied by 1.5-2. Figures of C coming from USA often are static values, so they should be halved. Most figures of C coming from Europe are OK (stated at 10 Hz)"

It is interesting to note that Poul Ladegaard of 'Bruel og Kjaer' determined empirically that the 'best" resonance frequency would be much higher (15Hz to 18Hz) than what is normally considered desirable. See his excellent AES paper published here.
