They remarked on the super clear mids and HF, "mids to lose yourself in, was one comment).
That is the difference passive radiators they are used to vs horn loading.
The evenness thoughout the hall was another comment.
Some thought there was a lot of bass 
It actually looked and sounded quite even across the frequency range on dynamic music Freq Resp.
That was another comment from someone who measures things.
I would have taken 2 or 3 subs for that hall if I could have🙂
