Mounting a driver off-center reduces cabinet diffraction effects.

Evidence

From Figure 6.65(a), we can see that the rectangular parallelepiped enclosure has significant diffraction effects. This is despite the fact that the driver is mounted off center, a strategy that reduces the effect of diffraction by reducing the number of coincidence effects. The cylindrical enclosure, Figure 6.65(b), does not seem to offer much improvement. This is due to both the presence of two edges and the coincidence effects caused by the central location of the driver between those two edges. An off-center driver would have improved the results. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 2161
