Abstract: Loudspeaker parameterizations based on measuring a transfer matrix is presented. This approach produces nine complex frequency dependent functions. While Thiele-Small parameters only capture the first piston mode of a moving coil speaker, the transfer matrix approach captures all the linear behavior of the speaker, including the diaphragm modes and internal geometry. Predictions of baffled response of two speakers are presented with the transfer matrix parameters producing better results than the Thiele-Small parameters, especially at high frequencies. The SAATI "Ares" acoustic simulator uses the transfer matrix parameters for effective simulation of complete devices, including proper porting geometry and dampening acoustic meshes for better audio tuning.
