Regarding measurements - some of you have probably seen Jim's setup. It was home-brew, but quite extensive. Of interest is that the swept sine wave told more about some aspects, and his "bleeper" which was 1/3 octave tone-bursts, told different aspects more clearly, and pink noise again a different shade of meaning. He correlated these chamber tests with outdoor normal plane and ground plane and up-firing from the sand pit. Part of his witches' brew was how he weighed and rolled with all those variants. When we went to the listening room, he would spread out graphs so that he and we could correlate different aspects with what we heard . . and make progress decisions.
Of note is that when New Thiel took over, they trashed Jim's gear and replaced it with a Klippel rig. Rob now has that rig, but neither of us has approached it yet.
