The Linear Array Transducer (LAT) is a tubular form-factor loudspeaker driver technology which, to a good first approximation, can be modeled by the standard linear time invariant small signal parameter (SSP) loudspeaker circuit model. However, to understand the behavior of a LAT to a greater level of detail, the SSP model can be extended with the addition of four additional parameters. The nature of these additional parameters in the model are explained. Additionally, the model is correlated to measurements of currently available LATs. Finally, it is shown how the LAT extended SSP model is approximated by the standard loudspeaker SSP model.
