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


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

Quad 57's! Peter Walker's marvels! True, they look like space heaters - but they have an overall sense of "rightness" that eludes many of today's big-buck designs!
roberjerman,

Are you sure about the 57s being time/phase coherent?

I thought it wasn’t until the 63s that they became time/phase coherent, with the driver made in to delayed concentric rings.
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.
