Actually it is the same effect as the "shocking up" (progression of a high intensity sine wave into a saw tooth wave), if sound were traveling though a pipe, then it is the intensity and number of wavelengths that govern this, the greater either is the greater the issue.
In a horn, the pressure falls with increasing area and so one finds for a given initial throat intensity, the problem is worse with increasing frequency and decreasing expansion rate. At the low frequency end of most horns response the driver linearity is by far dominant issue.
