Sundown neo pro 8s/6.5s

It's because of their fairly low efficiency. For a "pro audio" driver, they really aren't that efficient so they are going to run into issues faster in the midrange when you really begin to dump some power onto them, as opposed to a speaker 3-5db more efficient. I believe it was because Jacob was trying to get a bit more 60-80hz performance out of them as opposed to the very low q pro audio drivers, which general have problems below 100hz (although they destroy anything else above that point IME)

That's an interesting observation. I've not found TS parameters published for these drivers and have been wondering about them since I got them. But since then, I've bought a DATS and I think I'll pull one tomorrow and see what it reports, because I've not experienced the problems you mentioned.

I know the PRV Neo's are listed as 89dB efficiency, so not exactly PA territory. Never bothered to check on the Sundown or Crescendo mids...

When they first launched I asked Jacob.. may have even been before launch.. IIRC they are 92db/1w/1m. That's a good sensitivity overall for a speaker as a 2 way if you want it to be louder than most stuff bit still get down to 80hz.. however if your used to full on pro audio that can be as much as 6db higher well that means your putting 4x the power on the speaker to get the same midrange output. Also not sure about shorting rings.. many mid to High end PA uses them and it does help keep the midrange clean.. if your used to speakers that utilize them often non LE optimized drivers sound a bit ragged in the mids.

The neo.mids we're built well for their target groups specific app, but not everyone's cup of tea

That's pretty close. DATS read 93.51dB on a "broken in" Neo Pro 8 from my door. And I would agree with Jacob in making sure they work well at and just below 80 Hz. Fs on this driver is 81.42 so it's pretty much where it needs to be for a car audio door speaker. So they may not work flying in a cabinet above the dance floor in a nightclub but then, they're only "PA" speakers in that they mimic the build style of PA speakers. In the end, they're car audio drivers and so far, I've had no issues with mine dumping 300 watts each on them, which is double rated power.
