I’m using the cones but not the spikes and then shims in the back to move the angle more forward. I tried numerous positions to optimize the sound. My room is open concept 1200 sq ft, tile on concrete, glass door walls, some carpet on tile, furniture and no treatments.
The sound is never harsh, hard or bright… the soundstage presentation is big… and the Sapphires play big when appropriate and small and intimate when needed.
I haven’t heard the Xs… but will make it a point to track some down at some point.
