How about a list of speakers that are time and phase coherent? Thiels and what else?

Had a Meyer engineer bring a SIM over. He measured my horns and said he's never seen a phase response that good w/o DSP.

They're Exemplar Horns.

Hold on a second while I get my head out of its' listening clamp...

Most timing issues have to do with the same signal reaching different drivers, and can be mostly corrected by a properly designed crossover.  If the speakers sound good, I would not be too concerned about "time and phase coherence".

On the other hand, if you prefer to run test equipment (and music is mostly just a bother), then you may find hours of enjoyment testing for time coherence.

Excellent discussion about this by JA, interesting...
