Setup context
Use this cartridge reference with the Tonearm Match Lab to estimate cartridge-tonearm resonance. The key setup inputs are body mass, tracking force and 10 Hz compliance.
Reference data is best-effort and should be checked against manufacturer documentation before critical setup decisions.

Model-specific matching analysis
Its 6 g body mass is included in every total moving-mass estimate below. The calculation uses 20 CU at 10 Hz; this value dominates how strongly resonance shifts with tonearm mass. The stored tracking-force reference is 1.8 g. The database classifies this cartridge as Moving Iron.
| Tonearm effective mass | Estimated total mass | Calculated resonance | Interpretation |
|---|---|---|---|
| 6 g tonearm | 12.5 g | 10.07 Hz | inside the usual 8–12 Hz setup window |
| 10 g tonearm | 16.5 g | 8.76 Hz | inside the usual 8–12 Hz setup window |
| 14 g tonearm | 20.5 g | 7.86 Hz | below the usual 8–12 Hz setup window |
| 20 g tonearm | 26.5 g | 6.91 Hz | below the usual 8–12 Hz setup window |
| 25 g tonearm | 31.5 g | 6.34 Hz | below the usual 8–12 Hz setup window |
Calculation: f = 1000 / (2π√(M×C)), using cartridge mass, 0.5 g fasteners and the stated 10 Hz compliance. This is a setup estimate, not a laboratory measurement.
