Bass wavelengths are long enough to avoid cabinet diffraction but midrange wavelengths are not.
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. — David Howard, Jamie Angus, coustics and Psychoacoustics, 2212
