Aren't you asking for a driver specialized for midrange duty? Whatever they call the drivers, they are intended for wide band capable of 2-way, so not really a midrange.
It's a driver specialized for midrange duty, not 2 way for sure.
This is a genuinely interesting discussion. 🙂
I never quite know what is a good driver from the frequency response.
Juhazi's Finecone video is fascinating.

Dustcaps, cone material and damping, edges. All quite interactive.
Motors is something else. Underhung, overhung an' all that. TBH, I think there is no perfect answer, but some trade-offs can be balanced.
SB Acoustics seem to be moving towards flat frequency response with lively materials for this mid.
SB Acoustics :: 6½" SATORI MR16P-4
I'm absolutely certain it has some phase issues around 4-5kHz. Marked in Green. That's just cone geometry.
I also enjoyed wesayso's comment about a rising response that is easily worked with without much filtering here with 8" paper units. Which, IMO work like 6" polycones.
H1659-08 U22REX/P-SL
H1288-08 CA22RNX
Always hard to decide if you want to go with mechanical/material or electrical control of the slopes and breakups. I really don't know. 😕

It's beaming. A 6.5" with vented motor and Fs=31Hz, that's not a midrange but a subwoofer 😀
So i assume you have all seen the 7" mid from Scanspeak that is now available via Madi? Designed for small sealed enclosure with an f3 of around 90 Hz.

as well as the high efficiency 6.5" audax?

Which speakers used this? The data shows that it will be hard to match with many tweeters. May be fine for a 4-way.
The way scanspeak squash up their frequency charts exaggerates the rise
5dB differences for 60deg off-axis at 2kHz and for 30deg at 3kHz. And the 900Hz issue is in the mid band. The Satori 6.5" is not that bad on paper (kind of too good to be true).

Jay,
Given the 7" size, this seems like a driver for a horn type of speaker that would have to have a lot of dynamic range in the mid-range.
I don't really think it's intended for traditional DIY projects with a dome tweeter and 10" woofer. 🙂
Best,
Erik
