When the tweeter is mounted way high up like that, those speakers are meant to be listened at a fairly far distance from the speaker, we are talking by at least 3 meters. Especially those tweeters which are AMT tweeters. AMT's tend to have narrow vertical dispersion (not all, but most). So if you were seated where that chair is in that image, you would probably be missing most of the treble of that speaker (not that it matters since those speakers aren't hooked up to amplification anyway).
This practice of mounting the tweeters so high in flagship speakers is problematic. The higher the tweeter, the further from the speaker that the sound integrates, so the further you need to be seated back from the speaker for it to sound good. Some flagship or high-end speakers are designed more logically, but, sadly, there is an awful lot like the ones pictured in that image.
