Either my hearing is going, or Axpona had quite a few rooms which I felt the speakers underperformed. I remember the Paradigm being one of them, they sounded bright (Yes coming from a guy who owns the Persona 3F with the elevated trebble after 10hz) Nothing a bit of EQ and positioning didn't completely resolve for me.
One of the least impressive rooms for me was the Perlisten on wall speaker setup. We all know how good those speaker measure, but the bass was overwhelming and midrange felt lacking. It might had just been a bad recording or room, who knows.
As I reported in another post, i still want those powered RBH towers, they were simply amazing. Note the MFR, they should not release those speakers in that dark of black to demo, so hard to take a good picture, though the one on this site was very clear.
