Cabinet edges and centered drivers create diffraction that smooth curves minimize

Evidence

The main consequence of these results is that wherever possible the enclosure should be curved near the drive-units and that the drive-units should not be mounted in the center of the enclosure. In practice, they will have to be mounted centrally in the hori­ zontal direction, but they do not need to be so in the vertical direction. Under these circumstances, the most appropriate shape is circular. However, for the reasons outlined previously, an ellipsoidal shape is often more appropriate. — David Howard, Jamie Angus, coustics and Psychoacoustics, 2217
