  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.

I believe SPicas used a 1st order/4th order x-over configuration in their tc-50...with the 4th order on the mid-bass driver...designer John B. claimed through computer simulation tests that the 4th order had virtually no phase anomalies...I do know this...in terms of 3-d imaging...the SPicas are still one of the best...I also believe B&W uses a 4th order design in their higher end models...
