Horns: Why don't they image well?

Set them up right and they can image just fine.  

@Erik,

He is. I think every possible subject regarding hi-fi has come up already in the past decade or two.....Welcome wcfeil!

Another horn thread.
I’m looking for something that hasn’t been said before.

You seem new here... 

Eric,

I was being serious in a jokey way, you seem to knowledgeable  about speakers, cones, crossovers from your posts etc.
It certainly might be a time consuming challenge for you.
My Nagaoka BLH with a single Fostex Sigma 168EZ? 6" cone image quite well.

@gawdbless 

You seem a little bruised. 

Eric,

Why don't you design and build a pair of horn speakers that Images well, and then report back to us? Get yer tools out..........
3 way please................

And they're off!!!

stirring the pot again......

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

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.
