I read the article differently -- that the combination of chamber measurements and measurements on the pole allowed accurate readings down below 20 Hz...

Then again I was very tired when I read the article

Get some sleep and re-read

What Axiom does is measure subs outdoors on the pole, then they remeasure them in the chamber. They then create a correction curve so that the chamber results are accurate down to 20Hz within a dB or so to what they measured on the pole. Pretty cool stuff!
