Regarding vertical convergence :
I have often wondered about the effects of arranging horns vertically, such that their output converges relative to each other, toward a single point at a given height above the floor. I have seen Wilson Audio do this with their really big direct radiating speakers.
While it does not seem entirely natural, I will admit that it is interesting from a packaging point of view, as it allows stacking the horns higher, while maintaining the vertical arrangement. However, taken to the extreme, it will defeat the purpose of the vertical arrangement, and you may just as well locate the drivers in a random mass aimed at one point.
It may be possible that a little of this "vertical toe-in" could be tolerated if the point of convergence were far enough behind the listener's head... maybe. It might even be "interesting" ; I will experiment with this before designing the fixtures for my horns.
Regarding the Mid-Bass :
If these guys are using the main block as a Mid-Bass horn (as Romy's illustration suggests), then the story is getting interesting, and the plot is definitely thickening... It would however seem impossible to time-align this driver with the others.
Regarding the long tails on the MF HF horns :
If nothing else, I would guess these tubes would serve to provide a means of adjustment for time alignment ; meaning their primary function may be simply one of locating the horns in space, offering the possibility to move them axially (like a telescope), in and out of the main block.
