Nice, I've never seen mundorf bipolars, might use them some day since now I know of their existence. This forum brings perfection out of people. Whenever I see neat crossovers I hope and crave to attempt equal visual niceness.
I hate and love to lurk in your thread - loads of inspiration.
Here are the curves for on axis and 30° off axis FR.
Green 0°
Orange 30°
I also added Impedance curves
...... Can you take some measurements from the guest room please ?
For those irritated by the high resolution of the curves here is a "brochure like" curve.
10dB scaling
1/12 smoothing
Sound is wonderful. Still no cc battery in place, so it will be smoooother.
Absolutely wonderful Guido!
Congratulations Guido, they look quite nice in your room. Two comments:
Are they toed in enough? (OK that was a question.)
And second, As I look at my pair I think it odd that Ashcraft didn't make the UHF tweeter module the same width as the inner die-cast black section of the mid horn. On the factory DD66000s the tweeter modules is slightly narrower. On yours I see that you made it slightly wider... seems to me the lines would be cleaner if the black tweeter and horn sections looked like a single projected arc.
I am not suggesting you change yours... just noticing.
Tiny details like that aside, your set up and speakers looks very nice... I hope you enjoy the system for many years to come!

In answer to Widget's questions / comments:
>>Are they toed in enough?
The horn has the most regular frequency response when the listener and the 2 loudspeakers form an equilateral triangle, i.e. when the listener is sitting 30° off axis.
>>I [i.e. Widget] think it odd that Ashcraft didn't make the UHF tweeter module
>>the same width as the inner die-cast black section of the mid horn.
The upper horizontal line in the drawing below marks the transition from the inner die-cast black section to the lips. That horizontal line is also a tangent to the UHF module.
