Thiel 3.6's - Stereophile measurements

I have not had the benefit of an audition with these speakers. There are few dealers still selling them. My question is regarding the measurements which accompany the Stereophile review from 1993. The frequency response measurements show a big suckout in the midrange at 45" distance. At 10-15 feet is this suckout apparent? Are there any coherency issues with this speaker that I should be aware of? My listening position is 14 feet from where the speakers will probably be setup in my room.
