AB  - The cavity of concave diaphragms causes a typical variation of the radiation impedance, which has an effect on the performance of the speaker system in the frequency range where the wavelength is comparable with the dimension of the diaphragm. This paper investigates the radiation impedance and its effects on the sound pressure response of the whole driver with the help of a circular symmetric boundary element method for the infinite baffle. The electrical and mechanical properties of the electro dynamical driver are modelled with lumped elements. An approximation for the wide band radiation impedance of cone type diaphragms is given and compared to the exact results from the BEM.
