In this paper, we continue our investigation of the high-frequency and subsonic limits of the Klein-Gordon-Zakharov system. Formally, the limit system is the nonlinear Schrödinger equation. However, for some special case of the parameters going to the limits, some new models arise. The main object of this paper is the derivation of those new models, together with convergence of the solutions along the limits.
