Looking at some of the small (3 inch or so) fullrange drivers and the better ones seem to have excellent frequency extension and off axis response along with the ability to cross much lower than domes and the like so the question…..seems like a great choice to mate with an 8-10” woofer for a 2 way.
Certainly seems so and had they been developed way back when, I imagine there wouldn't have been many 'HIFI' 2 way woofer_horn systems.
In my experience, they work better as extended range mid drivers, & sound better with a tweeter added, but maybe I'm just getting old.....
I agree. The better full-range drivers are nice and can be enjoyable, but for the last bit of refinement/detail/air, a good tweeter usually helps. Frequency response doesn't tell you everything about this aspect.
Some 3” have better top than some tweeters. And working from 300-400 up, seamless.

not just modern drivers... One may find very good vintage FR drivers with alnico magnet and very fine sound at relatively low price. FR with helper woofer XO first order 2-400Hz makes an easy diy build.
I read once a doctoral dissertation which analyzed different types of tweeters with matched FR response to compare them scientifically. In blind listening tests no difference was audible. However if the specs are good you certainly can build good loudspeakers with the 3 inch fullrangers.
As you cover the important middle tones with one driver you get for free the time coherence of a point source. So you get something classical tweeters do not cover up.

I likely would have flunked that dissertation haha, on grounds of gross sampling bias. Out of billions of tweeter sample combinations he cherry-picked a few pairs with identical FR to write a thesis on....(Seriously as a methodology critique, I can pick out identical-sounding pairs of different tweeters too -- a very specific FR, but then so were his.)
Has anyone here ever owned two different tweeters with identical performance?

I have heard Seas fullrange driver in LXMini. I didnt miss a separate tweeter. I was pleasantly surprised at the highs
I have asked that question myself after hearing my lines with 18 pcs of 4 inch Visaton FR10HM with wizzers. I think it is the MUCH large lower frequency 500-2k capacity that gives the remarkable ease and low distortion in the treble that shines through. When you have 18 drivers, doppler is no problem as you cant nearly feel or see the drivers move at still very loud levels.
Backside - and its a big one - dispersion.

TNT; very interesting - I have 32 x Beyma 4" FR drivers and I was planning a similar experiment! I agree 100% that low excursion is a very important contributor to good sound.
Yes, these have some remarkable qualities - still, I regret I didn't buy a little better drivers. It was an experiment that came out surprisingly well. I will most certainly return to the line concept with a more substantial approach at one time.

Scanspeak 10f8424 has been used quite a bit, there is a very long thread on here where @xrk971 matches it to a Dayton RS225 in a Fast/Waw, seems to get lost of good review. Sensitivity is around 87dB/W/m
even if you get the best 3-4" driver its still going to be poor in dispersion. a dome can always be better than a woofer.
over on audiocircle there are some obsessing over fullrange drivers and claiming crossover color the sound or whatever. they even push 18" full range drivers (yes you read correctly)
iv found no quality in fullrange drivers at all compared to a proper 2-way-3-way.

300Hz for a 3" ? I thought small drivers like that needed to cross min at 700Hz o not sound 'thin'.... Maybe on a very wide baffle?
