A boundary element model is used to analyse a folded horn. Results from the boundary element model are compared to measurements of the throat radiation impedance and the far-field acoustic response. Further analysis shows how one-dimensional and lumped parameter models can be derived from the boundary element results, and used to gain insight into the behaviour of the folded horn in a loudspeaker.
