Abstract: In the present paper we study the effects of initial deformations and electric fields on the behaviour of the {\it electromechanical coupling coefficients} and on the shape of the {\it slowness curves}, in the case of progressive wave propagation in 6mm-type piezoelectric crystals along the symmetry axis, resp. in the plane normal to the previous axis.
