Is it me or is this particular test the perfect storm for this test to result the way it did?....what would be left to differentiate the drivers after they are set up?
Driver material
Off axis energy
Thiele specs
Random peoples Ears
Of these variables....left..which is the one that anyone is really surprised, did not show through?

Ok, so next step, HF drivers alone with sweep tones.
The ribbon didnt like the sweep tones. It's gone. Rest in peace, little fella.
Just before he died, I got a reading of 113db.
Now, the same sweep test but with the 3fe22, still with an highpass at 3khz.
So, not only it's still very alive, but we got a SPL reading of 125.3db (!) Voice coil not burnt, everything seems OK.
EDIT: That new SPL record of my livingroom was made in the very high frequencies, at exactly 10,650hz.

That is close to 10 liters of displacement!! Enough to kill millions of Covid-19.

what car, camplo...
There's no car here. I was talking about my cabin and my loft.
I'm using 4x 8w1v3 in my cabin and 4x10w7 in my loft.
If you like SPL, Tomahack, we should stop playing in the hifi sandbox and instead build a SPL room.
Few PA amplifiers, lots of drivers and lots of wood. Good to go for some ***-kickin' 140-150db of whatever frequency that gives you some chills.
So you're saying that ANY subwoofer driver with an output of 100db @ 20hz with a THD of 10% or less would be sufficient for your needs?
That's what you're saying, right?
I'd probably prepare a package for eBay: 2x Beyma + 2x 21's woofer. Don't need them anymore. 😉
I like the experiment, I'm starting to forget why its so controversial given how the test was done...hopefully the idea will continue as I eventually try to cross low in a horn...you know....200hz from my Axi identical to 200hz from my 15m...also hopefully beaming only limits my listening window size and not my perception of the signal, plus the benefits of lowered reflections...fingers crossed.

So Jon, you made this thread and I cant help but wonder what exactly are you looking for when asking which is better? What does better mean to you in the context of this thread's findings? .

Zachary, I never asked which one is better.
''better'' has no meaning for me.
Here is the title and my first post of that thread:
I was simply curious to know if someone on the forum compared both. Got my answers: as the response curves shows, the 4fe22 cannot really be used as a tweeter, while the 3fe22 can. On the other hand the 4fe32 is better suited as a midrange of even as a wideband, but barely.
Also, as tested today, the 3fe22 is capable of very high SPL if crossed high enough.
Overall, for my general needs, the 3fe22 is a more interesting driver.
Ok so I just EQd the 3fe22.
I can tell you this: I doubt I'd be able to identify the little 3'' cone from the ribbon. Without the EQ, ok, yes, I would give it a try. Would probably succeed a 17/20 score or even a 20/20... But now that I hear it with the EQ, flat from 3khz to 20khz, nope. That would be beyond my hearing capacities, for sure.
I'm not even tempted to try, as I feel it would be a total lost of time. I know exactly the pattern and I don't feel confident at all.
That being said, don't take that for cash and do your own experiment. You might as well be able to identify tweeters in your own blind test. I just don't think I could myself. And I have a very good hearing in high frequencies...
So,
Now all my doubts are confirmed in my mind. We are probably not talking about 360-7200hz but the whole audible range from 20hz to 20khz. It's not just the midrange, it's probably the whole 10 octaves. Once equalized, at matched SPL, it is most probably impossible to identify. Except via power response, if the context allows it, and distortion, if the level is audible.

It makes me a little frustrated, this experiment, to be really honest.
The high frequencies were "the last chance" in my mind to identify the drivers, one from the other.
I do not like at all the feeling that I feel now, to have invested in the past thousands of dollars in drivers, in tweeters, which essentially give nothing other than what a small PA driver of thirty dollars can give. It's a lesson in humility, which I saw coming, but it's still frustrating. Sorry to unpack all that, it is not relevant to the test as such, but I wanted to say it anyway.

I'm just curious how two drivers that once EQ'd sound exactly the same but once EQ'd in free air one is.... better?
What did you mean by better?
Why refuse to define better?

Did the test today with a 3fe22-16 ohms, but I just changed it for a 4 ohms version.
Can extract even more power from the amp now. It shows.
In theory I could get 6db more, am I right? But I don't feel like 131db of 11khz tonight. Wouldn't suit my pinot noir.

I said exactly that in the other thread:
I said I am not sure which is better in regards of all-around performance. Now I'm using the 3fe22 as a tweeter (3khz+) therefore it's pretty obvious the 3fe22 is a better choice, no? I don't see what's difficult to understand, and even less why that makes me a troll...
The 3fe22 as a better power response and is able to achieve higher frequencies... Lower Sd, duh.
If i'd need a wideband, maybe the 4fe32 would be a better choice, because it goes lower. But then again, once EQd what would be the most acceptable trade-off? high or low frequencies? And enclosure size requirement?
Both interesting drivers, but overall it's the 3fe22 that impress me the most.
Some of the drivers had to of been easier to achieve desired frequency response, than others? Which needed the least eq? Which needed the most?

Hey OP. Seeing your other test pop up on DACs made me think of something. Your use of the word “whatsoever” in your titles. It basically implies... whatever we tried or any way we tried. And like a lot of your statements you have to either remember the asterisk attached or you will soon find out the asterisk. The small print that explains how the conditions are the opposite of what you expect. You go in expecting the whatsoever and you get a unique circumstance only.
