Thanks for the reply, prof
6.5' seems close for Thiels. Seems like most listeners prefer at least 8', so I'm surprised to read about your set-up. Sounstage's measurements of the CS2,4, however, were taken at 2 m (~6.5') and the frequency response was outstanding at that distance (as opposed to Stereophile's inadequate measurement at a mere 50"). I hope your diffusor gives that result you want!
