Now that I looked at your speaker in a more detailed manner I have come to the conclusion that you should remove that lift and roller assembly on the bottom front of your speaker completely and let them sit flat on the floor surface. Give that a try and the speaker should be perfectly at your face and ear height and the tweeter will be at its premium position for listening in a standard listening chair.
THAT IS YOUR ISSUE of why the tweeter signal is going above your head.
PEACE! TO ALL.
