Calculate the vertical resonant frequency of your tonearm and cartridge combination. The result updates as you type.
How it works: Resonant frequency depends on the effective mass at the stylus tip (tonearm plus cartridge plus mounting hardware) and the cartridge's compliance — how easily its suspension flexes. The ideal range is 8–12 Hz: high enough to stay clear of record-warp and footfall vibration, low enough to avoid audible resonance.
