You would probably still need 2 small fullrangers wired parallel to meet the woofers SPL but since they would be playing mono, there shouldn't be any nasty interference between them. You could also designe the part of the baffle for the two smaller drivers to be at say 30 degrees between them and get even better dispersion.
i have to read a bit about loadspeaker construction
but i definitely think woofer + fullrange is one of the easier setups to manage
but atleast in theory with dsp this would be no problem, but i kinda like the idea of having 2 full range speakers on each side, just optically speaking or else it looks like a lonely bookshelf speaker x)
oh now i understood what you meant, neat idea, i would definitely prefer good high frequency dispersion specially if moving in the room with background music (what the speaker is intended for)
just to clarify, if i have a fullrange speaker - woofer - fullrange speaker setup, you want me to slope left and right side of the baffle each by 15° "backwards" on the edge, right?

i think this is the best idea so far it has a few advantages and can run purely run off a stereo dsp setup
im just not sure what dac/amp i should use, i had hifiberry amps in mind but if they are kinda crappy they are out..
The only downside of this setup would be, you'd need to find 8ohm drivers in order to wire them parallel and not give your amp a hard time which limits the choice of the drivers. That's why I prefer 2.1, or you could use a 4ch amp and bridge two channels for the woofer (if the amp allows for it) and run mono signal to the other two channels.
