Is there measurement that correlates with cohesive/pinpoint imaging?

I am currently using single-driver Omega alnico speakers which have the most coherent imagining that I've ever heard.  However, if I wanted to compare them with other speakers (including multi-way speakers with crossovers) in that regard, are there any specific measurements to account for?  Would measured delay between driver signals in a multi-way speaker be a useful proxy?

I just told you the answer 
Lots of speaker companies claim to have a focus on coherent imaging, but nobody has any idea how to measure it?
it is measured by frequency response tests
