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

The Reference 3As aren't either, simply because the woofer is run w/o a crossover and out of its pistonic range. 

Ohm Walsh Sound Cylinders claim to be, but I’d need to see the measurements to believe it. 

Maggie’s are not time and phase coherent. Single driver speakers are not (necessarily) time and phase coherent. Planars and electro-stats are not (necessarily) time and phase coherent. 

Just trying to stop this from becoming a “speakers we like” thread. 

Some people may be fooled into thinking something like the Wilson Speakers would be mentioned in a list like this because they make a big deal of time-coherence with their stepped baffles or sloped design. But they aren’t (as I understand) time/phase coherent/first order designs.

After a few glasses of whiskey, all of them are time phase coherent.
