Looks like plenty of baffle to me, Andy.
I think you are going to love the results if you go with the NEO8 arrays.
There are so many viable configurations with these drivers. I ended up with symmetric XOs at 260Hz and 3KHz, 48db/oct throiugh the DEQX and a 40Hz LR4 hand-off to a sub. That way no driver is close to breaking a sweat no matter the volume level.
Please keep us in the loop as you do this project.
Awesome frames, BTW.

The single sided baffle should be sufficient.
Guitar slim, Though I never used 48db filters, I did use LR4 and the tweeter was definitely stressed at my play levels at 4 khz, not to speak of 3khz. The compromise was 5 khz LR4 or B3. The tweeter does not have that much of an advantage over the Neo8 mids at 5khz and below. The Neo's dispersion is still pretty good at 5khz and detail retrieval is pretty much on par at these freq. Cohesion wise I liked keeping the low treble with the mids on the same driver.
Hi Satie! Thanks for your thoughts.
I never noticed any limitations of the ribbon with the steep slope at 3KHz, but then it's possible I don't listen as loud as you.
Maybe next time I'm playing with the DEQX I'll try raising the mid/tweeter crossover frequency.
Some time ago I had to replace a ribbon and went a month or so running the NEO8 arrays as mid/tweeters and was surprised how dramatic the difference with not having the ribbon "sparkle". Maybe not surprising.
Anyway I expect 5KHz is a good choice.
