AB  - A compression driver with an annular two-slot phase-plug coupled to the convex side of a hemispherical diaphragm is introduced. Magnetic and thermal domains are modelled using transient and static Finite Element Methods (FEM). Structural and acoustic domains are modelled as finite elements with boundary elements used to model free space. Structural and acoustic elements are fully coupled to both each other and the boundary elements. The application of these FEM techniques to the optimisation of compression driver performance is discussed and illustrated with results. The limitations of plane-wave tube measurements are also mentioned and illustrated with FEM and measured results.
