This is true, the Sabrina’s tweeter is fairly low, as was my Yvette’s when I owned Wilsons. I believe in the manual Wilson provides some guidance on setting tweeter height by adjusting the spikes, but that may change how the whole speaker sounds all the way down to bass response in the room.
If you’re using stock spikes, definitely consider trying some isolation solutions regardless just to minimize resonance in the speakers and improve imaging. I’ve used Isoacoustics Gaia footers which tend to raise the total height of the speakers by 1-3” compared to the spikes any speaker may have had prior. That might be just enough to make the difference you are seeking vs full out isolation platforms.
