  Time coherence - how important and what speakers?
I have been reading alot about time coherence in speakers. I believe that the Vandersteens and Josephs are time coherent.

My questions are: Do think this is an important issue?
What speakers are time coherent?

Thanks.

Thanks Roy ... I was not trying to suggest that Spicas are true time-coherent, because I did not know whether they were or were not. I had an idea that they were designed to approach time coherency, and if that is what makes them image the way they do then I'm quite interested to hear a pair of Europas to see if they will give me more of what I like about the Spicas with a bit more dynamics, and less of a recessed midbass. To date I've heard speakers that have better bass than the spicas, but none to touch their overall sound for under $1000.
