AB  - Models for a commercial compression driver were developed using transmission line matrices and Finite Element Analysis using the commercial package ANSYS. The models were compared with measurements using plane wave tube loading, and discrepancies investigated. The electrical impedance was measured in-vacuo to obtain Thiele-Small parameters without acoustic loading. A resonance was investigated and found to be air leakage into the magnet cavity. The development of frequency dependent damping in the matrix and FEA models was necessary to improve the simulation accuracy.
