The phase diagram of strongly anisotropic two-axis ferromagnet at arbitrary orientation of external magnetic field is built. It is demonstrated that together with a ferromagnetic phase there is possible the existence of phases with a tensorial order parameter: quadrupolar or quadrupolar-ferromagnetic phases. Spectra of bound magnetoelastic waves are investigated. Besides it is demonstrated that at large enough magnetoelastic interaction there is possible an active interaction of a magnetic subsystem with longitudinally polarized acoustic mode which becomes a soft mode at the point of orientational phase transition.
