I have owned my RAAL 140-15D dipole ribbons for about 15 months now and absolutely love them. I am planning a new build with them, "hopefully" the last (yeah right, right?). I am planning a nice project for a future man cave paired with Accuton C173-6-090 mids and GR Research Servo open baffle subs. Actively amplified with Hypex UcD modules and preamp/DAC/crossover/processor will be a highly regarded car audio Helix DSP.
The RAAL dipole tweeter employs a formidable faceplate. How have other owners of this ribbon tweeter integrated it in their designs? I think I have an idea for how I want to mount it alongside the Accuton mid, likely using a thin wood fascia around the outside to bring the faceplate flush (I am no expert with a plunge router). Looking forward to what others have done with these

Or do I go with the SEOS waveguide, something I definitely want to consider for my build, allows very low crossover for RAAL to cover more midrange:

For science, some examples from around the interwebs:
My prior build with SEAS Excels and 6x Acoustic Elegance OB15's (heavenly sounding bass!):
