Wow, another fantastic review. I really appreciate all of the time it must take to do these reviews.
That's an amazingly smooth early directivity index from a rectangular 2 way box speaker design. Looks like driver size, selection & crossover design were enough for a smooth directivity handoff. No fancy waveguides needed.
From the nearfield driver measurement chart, looks like the woofer was crosses over to the ribbon at 2.4khz or so? If so, great job on not really making a blip in that region on the polar plots (at least horizontally).
Looks like @Selah Audio nailed it!
