there is a couple of 2 drivers full size headphones, i wonder why there is no 2 way coaxial driver headphones, if the treble driver is in the center of the bass driver, coherence will be better

Do not know if you have heard the JVC SZ1000 / 2000 that is widely discussed in the Bass Headphone.
They have two drivers on each size, as well as a "bass tube".
There have been a number of headphones made like this in the past, but rather than a coaxial design where the tweeter replaces the phase-plug, it is simply two normal drivers, (larger) one behind the (smaller) other.
Usually the bass driver is heavily damped, covered and only one or two bass ports lead to the ear, so even this isn't truly similar to coaxial speaker design.
However, I can think of one headphone that replicates the idea fairly closely:
Ross RE-278 has two speakers, one on top of the other, both almost fully damped on the rear-side, but both almost completely open on the front side.
They're also jam-packed with electronics to tune the two speakers in some sort of harmony.
Honestly I think this kind of design has way too many flaws in a headphone application to be worth while, and the miniaturization of a true coaxial design would probably be a technical exercise at best.
Edit:
Just another thought I've had about the difficulty of miniaturizing this kind of driver technology is the driver to ear distance being a significant factor.
The further away the driver is from the ear, the less prominent mids and bass appear in volume, and the more trebly they sound (easy enough to test with any open-back headphone by pulling away the cups slowly).
In a coaxial design, the tweeter is even closer to the ear than the bass driver, which is why the vented design works best, allowing for the full air pressure of the driver through a narrow space allows for greater throw and more air flow.
In a fully open coaxial style design, there is very little throw and energy to the soundwave from the 'woofer', as proven by the Ross headphone.
i understand that, but look at the hd800 driver, it has a hole in the middle, there is a space for miniature tweeter, the companys can experiment with similar ring radiator driver and instal treble driver in the middle with crossover between the two, dedicated treble driver can have a lot smoother upper end, the other ting to consider is balanced armature tweeter in the middle, final audio have successful dynamic driver balanced armature full size hybrid but is not coaxial driver configuration, with ring radiator drivers coaxial configuration can be achieved
you're onto something
i also will make planar electrostatic hybrid, planar have excellent bass, electrostatics have excellent mids and treble
Bi-amped and ready to empty your wallets! how's that for a company slogan?
