I found these a few days ago...https://www.solen.ca/pdf/atd/14w2608agti.pdfAny experience or speculation about these drivers?

Why I said that Görlich sounded “different” and were used wrongly. Well, it was the low resonant frequency that I think screw those drivers. It was around 60Hz for small driver and it lead people to use Görlich in 2-ways configuration. Magico monitor was a perfect example of 2-way miss-use, listen them and you will hear what I mean. As good Görlich was at strictly midrange (with some questionable tone) as dead it was when a driver was forced to care lower MF and upper bass. Görlich is excellent MF driver but why drivers that shell work above 300Hz shell have a resonant frequency of 50Hz? Well, those mislead many people. What I experimented with my Görlich I did the same mistake and I drove them to low. I did have a chance however to hear 3 way implementation with Podzus’s  Görlich. It was a small Italian company, I do not remember name, and the made a floor standing 3-way loudspeakers with Zellatron’s version of Görlich drivers. It was ported Scan-Speak twin bass with, one MF Görlich and one Heil transducer for HF. They were presented at CES sometimes in 2000 and it was the “lost show” for them. They were in some kind of side room and no one spoke English among those guys, they play crappy music. The hi-fi show in other words. The speakers were set up strangely with very surprisingly good MF. I was attracted to it and a friend of mine and I were articulated something to those Italians. I do not remember already how it was, but I remember that I was bitching about the very inappropriate bass – it was obviously that their if not mistaken 300B amp was not able to handle the port’s secondary resonance, the current resonance.  Those Italians somehow understood us and told us that they have a solution for this problem, inviting us to stop by in the end of the day when they might to show off “another amps”. We stopped by, I think after hours, and they indeed had a pair of gorgeous looking monoblocks with 211 tubes of their own made, it was not demod at the show. However the sound of those thighs was nothing short of wonderful. I literally had no bases for complain. Regardless to the fact that it was 8 years back and I was much less intelligent about sound and much less critical that I now I still feel that it was very good. The sad part that no one ever mention about that company after then but those Italians  truly knew what they were doing.

I presume that if Görlich would do 5 then I might try them for MiniMe in 3-way configuration but the sensitively of 87dB is relay keep all of it out of the ball park. Even two of them would be far from my targeted 95dB… I presume that if Görlich stay with 100Hz-130Hz primary resonance then they would have fewer excursions and pick 5-6dB of sensitivity. Then they would need to stiff up the suspension it will be better for MF but it will be a different driver as no one knows how the Görlich’s cone would sound hard-suspended.
