🎧Tonearm & Cartridge Specifications

Tonearm manufacturer specification
From cartridge spec sheet
Typically 0.3–0.8g; use 0.5 if unknown
1 CU = 10⁻⁶ cm/dyne — most MM carts: 15–35 CU
100 Hz values need a ~1.7x correction factor

📐Resonance Frequency Rating Guide

Frequency Range Rating Effect on Playback Recommendation
< 4 Hz 🔴 Critically Low Severe warp-induced mistracking Incompatible pairing — do not use
4 – 7 Hz 🟡 Too Low Warp sensitivity, low-frequency boom Reduce tonearm mass or use stiffer cart
8 – 12 Hz 🟢 Ideal Excellent tracking, warp rejection Perfect match — proceed with confidence
12 – 15 Hz 🟡 Acceptable Slight bass resonance possible Usable; fine-tune if possible
15 – 20 Hz 🟠 Too High Bass distortion, groove mistracking Increase arm mass or use lower-compliance cart
> 20 Hz 🔴 Critically High Severe groove distortion, stylus damage Incompatible pairing — do not use

🧮Resonance Frequency Formula & Conversion Reference

Parameter Symbol Unit Notes
Resonance Frequency Fr Hz Fr = 1000 / (2π × √(M × C))
Effective Tonearm Mass Meff grams Arm mass + cartridge + stylus
Dynamic Compliance (100 Hz) C100 CU (μm/mN) Multiply by ~1.7 for 10 Hz equivalent
Dynamic Compliance (10 Hz) C10 CU Used directly in formula
CU to μm/mN — — 1 CU = 1 μm/mN (numerically equal)
Ideal Range — Hz 8 to 12 Hz for all standard tonearms
💡 Formula Note: The resonance frequency formula is Fr = 1000 ÷ (2π × √(M × C)), where M = total effective mass in grams and C = dynamic compliance in CU at 10 Hz. Always use the 10 Hz compliance value — if your cartridge spec gives 100 Hz compliance, multiply it by approximately 1.7 before entering it into the calculator.
💡 Mass Matching Tip: When pairing a low-compliance cartridge (like the Denon DL-103 at 5 CU) with a light tonearm, the resonant frequency will be too high, causing groove distortion. Add a headshell weight or choose a heavier tonearm. Conversely, a high-compliance MM cartridge on a very heavy arm will push resonance dangerously low, making warped records unplayable.

The resonance frequency of a tonearm and a cartridge is the specific frequency at which the two component interact with each other. The tonearm and the cartridge can be understood as a spring mass system, and as such, will naturaly resonate at a specific frequency based off its physical properties. The physical property that relate to resonance are the effective mass of the tonearm, and the compliance of the cartridge.

The effective mass of a tonearm is the total weight of the tonearm from the pivot point to the stylus. The compliance of the cartridge is a measurement of how much that cartridge can flex under a specific amount of force. Thus, the effective mass of the tonearm and the compliance of that cartridge determine the resonance frequency of a tonearm and cartridge system.

Resonance Frequency of Tonearm and Cartridge

Resonance frequency must be managed in that any vibration in the system (caused by turntable motor, footfalls upon the turntable, and warped records) can introduce rumble into the music that is played through the turntable. Rumble occur at frequencies below 20 Hz, but the resonance frequency of the tonearm and cartridge should ideally fall between 8 and 12 Hz. If the resonance frequency of a tonearm and cartridge system are too low, it can cause the tonearms stylus to bounce upon warped records.

However, if the resonance frequency is too high, it can cause the bass of the music to distort. Thus, the resonance frequency of a tonearm and cartridge system should of be set to a frequency that is below the audible range of human hearing yet high enough to avoid rumble from the turntables vibrations. In order to achieve the proper resonance frequency for a tonearm and cartridge system, a person must understand the relationship between the effective mass of the tonearm and the compliance of the cartridge.
