Cms parameter

Hi!
As far as i can understand, there is a significant inverse relationship between power handling and the Cms-parameter of a driver. It seems that drivers with high power handling tend to have a lower Cms-rating, which means stiffer suspension.

What are the "downsides" to a low Cms-rating? I can't see a strict relationship between sensitivity and suspension stiffness, but i might be wrong.
 
A stiffer suspension results in a higher resonance frequency, if the moving mass is kept equal. This in turn means that the driver has less low frequency extension. Furthermore, a stiffer suspensions results in a higher Qes unless the motor is stronger to compensate.

Greatly appreciated!

So when looking purely at T/S parameters in regards to midrange performance, Cms is more or less irrelevant when comparing drivers. I guess that leaves Mms as the most important T/S parameter for midrange quality.
 
You're welcome!

Mms influences efficiency but is not related to quality, if quality means harmonic distortion, smoothness of the frequency response and dispersion. Those properties are not described by T/S parameters.
