Here's the stereophile vertical response measurement of the Impact Monitor:

Tekton's are way more height sensitive than a normal monitor speaker due to the lobing effect of so many tweeters. You really can’t be more than 5 degrees above or below the tweeter array or you will be outside the sweet spot.
Whereas the Buchardt S400 is going to be the complete opposite. With the waveguide it will be much less sensitive to speaker height and will radiate sound in a more uniform fashion on the vertical plane.
Here’s the Revel M106’s vertical dispersion which has a similar style of waveguide to the Buchardt S400. You can see it’s much less sensitive to vertical placement.
