This may help;
http://www.prosoundweb.com/article/far-field_criteria_for_loudspeaker_measurement/
"A very small loudspeaker might possibly be measured at 1 meter, but for larger loudspeakers it's a different story.
For large devices, the beginning of the far-field must be determined, marking the minimum distance at radiation parameters can be measured.
The resultant data is then referenced back to the 1 meter reference distance (Figure 1) using the inverse-square law."
