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

@prof 
The new Meadowlark speakers are coherent. They are fully active with onboard DAC and they have amps for each driver. The older Meadowlark offerings were a more traditional coherent speaker. Like the newer Meadowlark, the Gaylen Sanders are fully active coherent speakers.I believe the Kii speakers are also.

Others are Dunlavy, Ascendo, Green Mountain Audio, Intuitive Design, Essence, and Mosaic Acoustics. 

I was referring to severe peaks and dips.

It is still not true. 

If time coherence was that important every manufacturer would be doing it.
And every audiophile would insist on it.

Another untrue statement. It is difficult to do correctly for the manufacturer, and many people have not heard it done correctly. There are also plenty of people that just don't care or find that it doesn't matter to them. That doesn't make them wrong or right, just as wanting time and phase coherence in a speaker doesn't make those that enjoy it wrong or right. To say that is not a valid approach to building speakers is just not true.

If you give me your green mountains, I'll make them sound ten times better just by upgrading the crossover.

Maybe you should design, build and market your own speakers. Then you won't have to spend any more time looking for the perfect sound as you asked for in another thread. You know what sound you want and you feel as if you are a genius in respect to speaker design. DIY would seem to be your perfect answer to your perfect sound.

Most people agree that frequency response is an important factor. Everybody can hear a peak or dip at any frequency. The same cannot be said of time coherence.

Time coherence is at worst a myth.

Not everyone can hear peaks and dips in frequency response. There are any number of speakers with incredibly ragged response that people love that prove that beyond a doubt. In the same vein, there are many that find the virtues of time coherence indispensable to their listening. The statements of absolutes are ridiculous.
