Checked against the manufacturer's published specification.

The maker quotes compliance dynamic @ 100 hz (jis), so the 10 Hz figure the resonance formula needs is a conversion. Treat the results on this page as approximate.

On the Clear Wave — 11 g

12.3 Hz
481216 Hz

Above 12 Hz. The resonance is creeping toward the audible band and can colour the deepest bass. A higher-compliance cartridge or a heavier arm brings it down.

With the ceramic headshell spacer (13 g): 11.6 Hz

Based on a compliance figure converted to 10 Hz, so treat it as approximate.

Assumes 0.5 g of mounting hardware.

On other arms

Arm effective massResonance
8 g 13.4 Hz above the band
10 g 12.6 Hz above the band
12 g 11.9 Hz ✓ in the 8–12 Hz band
14 g 11.4 Hz ✓ in the 8–12 Hz band
16 g 10.9 Hz ✓ in the 8–12 Hz band
20 g 10.0 Hz ✓ in the 8–12 Hz band

Figures are as the manufacturer publishes them. Compliance measured at 100 Hz or quoted as static is converted to an estimate at 10 Hz and marked with a tilde; treat those results as approximate. Suspensions also vary between samples and soften with age, so a calculated resonance is a guide, not a verdict. Spotted an error?
