Not sure why. My most recent build has some design cues from Wilson's Alexandria but incorporates tilting adjustment at the speaker's base instead of up above. If using a planar driver like the NEO 3 solo, it makes sense to put adjustability somewhere, whether tilting the entire speaker or a subset of the drivers to maintain the desired geometry.
If I'm reading you correctly, tilting for listening while standing is likely to compromise seated listening and tilting for seated listening is likely to compromise listening while standing - unless you have Napoleon's physical stature. A small array would be a better approach with this driver in terms of reduced distortion, dynamics, bandwidth, and dispersion. But that would require a little more design ingenuity, testing, and enclosure construction skills.
