Ran the Gaia's on my NX-Tremes and loved them, a couple of points, they add at least 2 inches which will raise the tweeter height, you may want to raise the rear of the speaker to re-align, this is less important if your listening position is further away, I probably not use those if your in the near field. I had my speakers placed on large tiles as my carpet was quite thick, worked like a charm, increased speaker focus.
Cheers,
