Horns: Why don't they image well?

I head a pair of Sadurni Acoustics speakers (the Miracoli) that imaged really well. They're overall the best horns that I've heard. Very expensive, but very good sounding. 

Like I said before Kosst, you're a good man. The La Scalas were playing in some pretty deep water there and held there own. Imagine optimal setup. Yes, they can image, but the dynamics make for a more lifelike presentation too, don't you think?

I agree that there isn't any bass way down low. They actually play very well with some solid state amps, and other more powerful tube amps as well. Like any speaker, it brings out different strengths and weaknesses.
