What about this one? Tang Band W8-1772 8" Neodymium Full Range Driver
Or this one? Dayton Audio PS220-8 8" Point Source Full-Range Neo Driver

Actually I realized the horizontal width of a 15'' driver would be awkward since it would extend beyond my face..not that I'm against it if it sounds better anyway.
Good point, but I thought .7 was the minimum for OBS/infinite baffle?
How relevant is qts when the driver is sealed around your ears?

Those full range drivers have whizzer cones.
I would caution against using them, as the whizzers could result in a piercing treble when the 8" speakers are placed close to the ears.
A single diaphragm 8" speaker may provide a better frequency balance in your application.

Not the same. Take any open FR driver and put it close to your ear. Notice the bass?
Doesn't need to be sealed around your ears, just positioned close to them.
A Qts of 0.7 or above is suitable for a free-air application such as yours.
There has to be suitable mechanical and electrical control of the moving cone when used in free air.

I don't have any FR drivers lying around so you tell me.
Any reason why I should not just seal them around my ears?
100% of headphones I've ever seen have earpads to seal the enclosure around your ear. I assume this is to prevent bass from escaping.
I also keep imagining the sound getting corrupted if the sound from the drivers get cross coupled with each other since they are pointing in each others direction.

Yes, cross coupling is what differentiates loudspeakers from headphones.
Headphones do not allow cross coupling, so do not reproduce the stereo sound field as well as loudspeakers do.
Do want headphones or head speakers?
I think head speakers should not be sealed to your ears.
But unlike normal speakers these would be pointing at each other. I would think the cross coupling effect would not be positive in this scenario.
Dynamic headphones are actually small full range drivers...so using fullrange speaker as a headphones is being done on daily bases.
Going up in the size of full range speaker is problematic, as laws of physics dictate that breakup point for cone speakers is decreasing with increasing size. At certain size heights are messed up, to me this happens once you go above 4-5".

Yeah but if you use a high sensitivity full range driver that is designed to be used as a full on speaker and not a headphone driver then you will be using it far below its intended SPL when placing it against your head, this means the excursions will be far lower than normal.
Wouldn't this counteract the cone breakup issue?
