actually this is not so much about horn loading ribbons as it is about curving them, but also horn loading.

look at this horn:

now imagine a ribbon of approximately same dimensions as Raven 3.2 MMX but placed sideways.

now imagine that this ribbon is not straight but curved into an arc. and finally that it is loaded into this horn.

only problem with this is obviously what's going to hold the ribbon up in such a position but i think it can be suspended on thin elastic bands - really thin.

another question is - why ?

well because normal ribbons have too much horizontal dispersion and not enough vertical. my proposed solution is to extend dispersion along one axis by curvature and limit it along the other by means of waveguide/horn.

it doesn't really matter if the resulting curved, horn loaded ribbon is horizontal or vertical but i think that a horizontal one would be easier to integrate with the rest of the speaker ( for example with a midrange horn by allowing for a closer CTC spacing )

what do you think ?
