Horns: Why don't they image well?


Anyone have a theory?

Horns use a very large waveguide - the energy arriving is not a point source for all frequencies they produce  - imaging therefore suffers slightly. The shape of the horn is critical - large spherical horn designs will image best - like Avantgarde. Intermediate horn designs suffer most. Very small horns like the waveguide on a tweeter also work perfectly because they are small enough not to affect imaging.
stirring the pot again......

I admit it, it's true. But I learn a great deal this way too. :)
