1.5g Mms and 1.8Tesla Magnetic circuit: What do you think?

Sorry I don't know whether I'm understand you correctly, but I think you said "if I'm reading the intention correctly, it's to minimise the baffle area to the extent that it's essentially the same size as the driver itself, which can produce interesting results. And if I'm reading the intention correctly, you address any potential issues with early reflectons coming back through the cone."
In my understanding, your understanding is correct, but I don't get what 'interesting results' indicates. Can you please build on that?

Exactly what you'd expect from almost no baffle: significantly reduced baffle diffraction effects. Still needs to be fair-shaped of course.

With all that said, if you're planning on having it up-firing as an omni-directional system (which a couple of the speakers you link to appear to be) this becomes something of a moot point.

>this becomes something of a moot point.
Is it because the speaker which should be listened at an angle of around 90° like omni-directional system can ignore these harmful influence for some reason?

In omnidirectional speakers most of what you hear is diffraction. So a bit more probably won't make a massive difference. You may need some HF support with the 83, since while its off-axis performance is better than some, it's still moderately directional at higher frequencies.
