- Resonances should stay between 5Hz and 50Hz for payload masses up to 50kg The axial stiffness of the struts (between two flexible joints) should be equal to $\approx 10^5 - 10^6\,[N/m]$.
- This corresponds to strut stiffnesses of $k \approx 10^5 - 10^6\,[N/m]$
If voice coils are used, this corresponds to the axial stiffness of the membrane guiding the moving part of the voice coil.
