I have the 12" dayton PA 310
Have used it to 1khz with a large wave guided ribbon, but to my ears the woofers at it best below about 400 hz. Im not convinced that the response between 400-1khz is as good as I want.
So want to throw a midrange driver around 5-7 " in the mix. It will cross to a ribbon above that at around 2 khz.
what would be a good mid for this? I see not too many mids that are above about 92 db AND I do not see the FR of the more sensitive mids looking as linear as the lower sensitivity stuff

I am using the SB Satori MR16P-4 and am very happy with it. It has a very wide bandwidth and high sensitivity as well. Hard to beat performance especially considering the price range; definitely worth serious consideration. (The SPL is probably closer to 93 than 92 dB according to a few 3rd party tests and reviews)
Satori looks like a good option for wide bandwidth linearity.
All the high sensitivity pro stuff will have a rising response.

The pair I have measure similarly. Not bad considering they're a decade newer than Zaph's tests. Haven't decided exactly what to do with them yet.
Too many drivers, too many potential designs, not enough time. First World problems eh?

Hard to go wrong with B&C these days. Their consistency is getting very good.
Same here. Brand new drivers taking up shelf space. Always want to try something new. Including the OP's custom ribbons.

Time, fate, money, Ha
Was hoping to have legal stuff finished by now but my "day job" has eaten the entire winter. Once everything is in order I plan to sprinkle a few pairs of the ribbon around to some here on forum to play with....
PA310, on axis goes way up, I have one in a Karlson K12 knockoff where the mids sound like they're 10 foot under water. A Pyle pym1298 (~same as Eminence Kappa12a) and rated ~99dB sensitivity sounds clear in the same cabinet. With PA310 rated 96dB - does one want a mid speaker rated at least 96 to match?
there's one inexpensive Lavoce 6" with a very good graph - is it sensitive enough for the job ?
- if so I'd like to make a fake CV "S1" with my PA310
LaVoce WSF061.52 - 6.5" Woofer

do you think the Lavoce 6.5 would keep up with PA310? A look at it by itself with hornresp says its pretty much thermally limited in a half-liter chamber. Impedance does fall somewhat below 4 ohms with the filter values shown.
.
Also - what's a good cabinet for PA310 ? I like the idea of a little 6th order reflex bookshelf speaker. A floor standing MLTL might be another option.

B&C 6MD38 is my go to 6” mid. I’ve used it in at least 6 projects over the past 10 years. I’d let to go to 3khz LR2 to a ribbon as there’s no real center to center distance lobe to worry about. High passed at 400 it can take more power than you can stand.
ScottG - that's a cool 5 - do they work well on horns? I'm old and not in good shape - just musing on making a Cerwin S1 knockoff of sorts with re-capped Interface B EQ box laying around. I'd like to keep the mid cheap - if possible. Am not super fond of PA310 (its just not bright enough to play at all in a Karlson K12 where a Kappa 12 will work very well) It may be a very good woofer once supported with proper mid and tweeter. Maybe a small round waveguide would suffice for C-V's "Dhorm" I briefly had a pair of Cerwin Vega S1 in the early 1980's which ran from a DH200. The supplied EQ box was noisy and "hissed". I'm not sure how good of a speaker it really was - BUT it would play loud for a little direct radiator box😀
btw, I do have Delta Pro8a - besides being 8" frame, don't know what tweeters would reach down to it - ?

Don't know. I'd guess either would work well depending on the design and what you want to accomplish.
Though only 4 ohms, I'd probably look to this driver for horn-loading (..though it isn't exactly cheap):
Dayton Audio PS65LP-4 6-1/2" Ultra Efficient Low Profile Full-Range Driver 4 Ohm
-in the right horn you should be able to average 100 db (5 ohms) up to about 3.5 kHz, with a workable low-pass character above that.
