AB  - In this work a combination of matrix analysis and a fully coupled FEA is applied to modeling and design of horn drivers. The proposed method makes it possible to calculate the 3-dimensional model of a compression driver that considers all its details and components including glue joints, complex mechanical behaviour of the diaphragm, acoustical properties of compression chamber and the phasing plug. This results in the presentation of a compression driver by four complex matrix coefficients A11, A12, A21, and A22. The method is very efficient in design and optimization of horns and waveguides. Each time a new iteration of horn’s geometry is made, there is no need to run the fully coupled model of the compression driver. Instead, the complex matrix coefficients are used as input parameters for horn modeling.
