i think the good image comes from the fact that they will have a narrow coverage pattern, so less waves hit the walls and generate phantom images of the speakers. since horns are directional and your big drivers are directional at higher frequencies due to beaming and directional at low frequencies due to the dipole calcellation, its a good setup for image.

I was actualy thinking of a horn with no back chamber, goint to ~100hz-500hz
Smallish, yeh....HORNish. I think you lose some of the bottom octave without the chamber.
Any horn specialist around?

I use an 80hz front horn with an 8" driver and no back chamber and I estimate the front wave to be up around 18-24db from the back when listening in front of the horn. The particular horn/driver combo sounds better without the back chambers I've used with them and there is little that the reactance annulling of the back chambers does to effect the bottom response of the horn.. A front horn that goes to 80hz with little ripple is not small. Mine are around 50" long.
