I thought you were joking, looks like you really had problems with vertical shift.
Philharmonic BMR Monitor directivity:
Horizontal -6dB beam width 160° (+/- 80°)
Vertical -6dB beam width 40 ° (+/- 20°)
Reference:
Sitting at a typical 10ft (~3m) with +/- 20 degrees you have +/- 3.64ft (~1m) vertical shift from the reference axis.
If you are sitting at arms length to the speaker, eg. 80cm, then +/- 20 degrees is about +/- 30cm (1ft) vertical shift.
TL;DR?
Setting up a speaker such at the design axis is near the main listen position is important, whether it’s a dome, cone, or planar device driver.
