Long bass wavelengths diffract less because they exceed cabinet dimensions
Evidence
Diffraction at bass frequencies is generally less of a problem, because the wavelengths are large compared with the cabinet size. However, if the main cabinet contains midrange units then it must also take account of diffrac tion effects. As this enclosure must also contain the bass units, and must sit on a surface, it is not possible to have a spherical enclosure. Instead, the curvature can only be arranged in the vertical axis. — David Howard, Jamie Angus, coustics and Psychoacoustics, 2212
