i agree for the price of the hype , same thing with purifi drivers , this one seams good to me and a good price but you need to put it in a small enclosure

Why do you find that attractive, out of interest?
The response curve on the datasheet does not look attractive to me - if you EQ away the hump then its rather inefficient, and the off-axis response looks worse (or at least no better - but the 60 degrees looks poor to me) than a 10cm cone?
Am I missing something?
yess your are missing a Moving mass of 3g that's why some prefers Dome or compression driver midrange than cone driver ..
Yes, reading the thread to prevent asking off topic questions 🙁
Why does that matter in and of itself? The dynamics are a combination of the moving mass and motor strength, surely, and a poor combination will show in the frequency response, decay, and distortion measurements.
So those who are not in total ecstasy about large dome mids are declared trolls from now on? Jmansion raised perfectly valid points: the fact that a thread is dedicated to a particular type of radiator does i.m.o. not imply questioning of concept is not allowed.
It's an open forum so they're isn't really "allowed" or "not allowed". But diyaudio.com threads seem to have a problem staying on topic.
Profiguy's intent of the thread was clear in post #1...

And quite often people just chime in without checking.....MD60N has been subject of discussion here already.
Try to use the search function a bit more often.
Thanks for the post #s. I actually searched, restricted to this thread, but none of the posts by Profiguy came up. I probably included the "-6" suffix or something that was more restrictive.
I have. What do you want to know?
Also did a quick & dirty comparison to M74A ... when you want details and "truth" the hard membrane is what you want.
Unless you want a wide and even radiating speaker ...
Also you can cross over at 4-500Hz and get more sensitivity as your lf drivers will give you anyways. And a good 1" dome will still have more resolution as your 400,- compression driver + horn.
For every concept there is the right solution ... 3" midrange and 1,4" + horn is a totally different concept.
Your statement on resolution isn’t empirical…..some would say that the lack of power compression and HD would reveal MORE of the resolution of the recording
And some would say the point source presentation without lobes or combing between drive units…..without additional inductors and caps….would be the more revealing solution.

I picked up a PAIR for $144 and was going to offer to loan them to Profiguy if he had not tested them. I didn't see where he had, but my searching skills clearly need improvement as demonstrate by daanve.
I'd like to know your subjective impressions of them, but also any thoughts on how low and high to use them to get the best performance out of them.
This statement correlates with my own subjective observation. I don't know if it is generally true, though. If it is, I suspect that it may be related to diaphragms with their breakup out of band (band being controlled by the filter) vs those that have high internal damping (and thus displaying minimal breakup). (However, as often stated, diaphragm material is only part of the story).
I am reminded of the old Morel MDM55 (soft dome) vs Dayton RS52 (aluminium dome) debate...
I also think the material itself is not the source of typical sound. But there is typical behaviour with different materials. I see 3 types of behaviour (and of course a mixture of these).
*) Hard membrane with breakup far outside the used range. -> perfect piston behaviour in the range, membrane follows the movement of the coil "perfectly". These sound natural and very detailed for me. But when you have a bad recording or stream ... it's not always "fun". But magic when the source is great.
*) Hard membrane with breakup closer to the used range. I often disliked the sound of these, from tweeters with resonances at 22kHz to 17cm metal midranges. They sound obtrusive for me - not sure why.
*) Soft and dampened membrane. These don't follow the voice coil perfectly even in their transmission range. Soft dome tweeter often start at <10khz not radiating with the complete dome (you see a different off axis behaviour as a hard dome would do). When compared to a good hard dome I always hear some colouration of the sound. When NOT compared... it can sound very good and relaxed, the right thing to listen to music of all sources with a glass of wine ;-)
A mixture would be ring radiator tweeters for me. Soft dome but resonances way out of the audible bandwidth. Like the sound very much but they often have narrow radiation at high frequencies - a hard dome can do better.
Dayton RS52 ... I always reduced the level about 1-1,5dB cause there was SO much detail it was quicky not enjoyable to listen to. But these are good drivers! With M74A I had not the feeling to need to reduce the level, but it was only a quick test.
You know the HiFi Compass measurements?
https://hificompass.com/en/speakers/measurements/satori/satori-md60n-6
It's not the lowest THD driver but the rest works well. They had an early model, my MD60Ns measure better at low frequencys. They are very sensitive to back chamber dampening, I belive they changed something here after the early units.
Nr. 0 has a litte different dampening in the back chamber. Attention - these are 2dB steps of the scale!
The driver behaves well at the upper and lower part of the range. I cross my tweeters low, so no issue with the upper range. THD only starts rising relatively gentle under 600Hz at high levels - so this is for sure a possible crossover frequency.
It is my empiric result. And I compared a few speakers up to now ...
Power compressin of a 3" midrange? 🤓 Your tweeter will blow up before you have power compression of an M74A. Literally. I showed the measurements here
https://www.diyaudio.com/community/...th-a-modern-3-midrange-3way-prototype.408882/
When all the membranes have perfect piston behaviour in their transmission range and follow the voice coil perfectly - that's potentially more true to the original as a 75mm membrane through a compressoin chamber and breaking up <10kHz.
Therfore you use active crossovers for exact delay and phase between the drivers. Close driver distance.
But as I sayed - 2 very different concepts! Many rooms call for a speaker with directivity! Of course a speaker with directivity has it's benefits in such a room which is more important as the last little resolution.
With a controlled room and closer listening distance - a compression driver has not the resolution/naturalness of a M74+T25B combination.
