A high value of the symmetry point xc(x) at small displacement amplitudes x » 0 indicates that the rest position does not
agree with the minimum of the stiffness characteristic. This may be caused by an asymmetry in the geometry of the spider
(cup form) or surround (half wave). A high value of the symmetry point xc(x) at maximal displacement x» xmax may be
caused by asymmetric limiting of the surround.
You can find a detailed description of these non-linearities and their remedies in the papers
