That tweeter's dispersion performance is so nice, but the other parameters are purely mediocre compared to that purifi woofer. Something like the Bliesma T34B has much better performance regarding THD and control of resonances (though also in a different price category).

I wonder why SEAS doesn't release a higher end version of this very popular tweeter. They manufacture the Beryllium dome for the Grimm speakers (and thus should be possible). Brief measurements of that driver can be found here: https://vcllabs.com/transducers/#tweeters (under the name DXT-Be).
Developping a waveguide with similar waveguide is fairly complex.
