Nice build.
Just thinking aloud : those small speakers reach quite high, rather than adding tweeters which should also be configured as a line array matched to the main one, etc, I would just EQ current speakers for flatness and extension, and call it a day.
A modest correction would do a lot.
I would second that. I feel no need for a tweeter when using 3FE22s. Do you use any frequency shading on your line?
Agreed….You‘re working outside of the classic Line Array principle here….. more a multi driver approach to a Line Source…..which IMO is the MUCH better option for home use where the listening position is about focus and sound stage instead of raw output.
I’d apply some power tapering to the 3FE portion…..break it down into 3 groups of four with the the central 4 producing the lions share. Add an inductor to the 4FE portion for a low pass filter around 350hz or so……OR power the system with multi channel power and DSP……6 channels and 3 DSP units

Ok thanks for your suggestion.
I will concentrate more seriously, with adequate equalization, with my DSP.

The tricky part is that there's two options and neither are ideal:
1) You can use a full length line of tweeters, but then you'll need about 48 tweeters and that's going to be expensive
2) If you use less than a full line of tweeters, the beamwidth will be a mess
I personally don't think the treble on the 3FE25s is particularly good. They're basically cheap efficient midranges, but the treble doesn't compare to a Tymphany TC9 or a Scanspeak 10F
I love the Faitals and think they are at the top of the line for 3" and 4" type of cone drivers. It is also a matter of taste, but I like the sound of it as a mid-high driver.
EQ is your tool, so work on that. Take care of the bump around 12K that masks the higher frequencies. Will never be top of the bill as a cone driver is not build to handle really high frequency in a nice way. If you smoothen them a bit around the 12 K and let it roll off, you will get a nice high-end. My trick is not to add what you are missing, but turn down what to loud to start with. With the 12K, they have a tendency to be a bit shouty, hence your ears tell you that you are missing the real high's, although they are there but mor in the background. Looking at the SPL of the driver mentioned by Patrick,
I use the 4FE32 for portable PA, and that's the best use for these, like the High frequency of the PA.
Adding a simple tweeter is barley noticeable, combined with the number of drivers you use likely overshooting the tweeter, apart from the input of Patrick. The fact that they are cheap does not really mean they are not good, I think they are, just work on getting the sound you are looking for, which is a matter of taste. Like a said, pull down what you don't like is the best option not spending loads of money, as this stack must have cost you already a serious amount of money. Maybe compare the frequency plot of the 3FE and the 4FE to begin with, I would personally never have used the 3FE, but just go for the 4FE, combined with a high efficiency tweeter in the Dappolite setting..

what about a line of microspeakers? https://www.digikey.com/en/products/detail/cui-devices/CMS-151135-078SP-67/9561105

as your line is full length I would recommend giving each driver the same signal and also having a full length tweeter line.

Thank you for your comments, of course, this is a project that requires a lot of turning
I take good note of your suggestions.

I haven't used these two speakers. The idea was inspired by this thread: https://www.diyaudio.com/community/threads/array-of-micro-speakers-with-shading-in-ath4-horn.391947/
Microspeakers are typicaly used in devices like laptops, they are bass and SPL limited but can go lower than traditional tweeters reducing crossover issues and if a full length line of them is used the maximum SPL will still be decent. They are also cheap.

Those tiny things are a joke. Not enough SPL up top to get decent levels with higher power levels after EQ is applied.
You'd be better off with the tried and true Tymphany TC9s. The power handling is sufficient to maintain enough top and bottom end when EQed and they sound absolutely fantastic overall, even without a sub.
