The response of a loudspeaker system employing a baffle is modified by diffraction at the baffle edges. Numerical solutions are derived using a model based on the geometric theory of diffraction to examine the major features of the diffraction process. From the model it is shown that a smoother frequency and step response result, provided the drivers are placed at unequal distances from the sides of small regularly shaped baffles or if small irregularly shaped baffles are used.
