As i said before http://stereophile.com/floorloudspeakers/wilson_audio_specialties_maxx_series_3_loudspeaker/index6.html
here is the measurement of the 3 , he puts the microphone on 1 measurement on the same spot as the ear would be in a certain listening room( mike fremer ), as english is not mu first language i dont know exactly when he means degrees or distance , he probaly measured the MTM and also the total output including Bass unit "in a certain room "
For my own designs the minimum distance is 2,5 meters , bass is omnidirectional yes , i dont exactly know from which exact frequency , anyway i find the bass output fairly complicated to measure correctly.
You can also ask a wilson dealer , if you find somebody with a good frequencyresponse measuring tool he could then measure exactly what you hear on the hearingspot and what changes as you move the speakers , and the measure again
