Wide dispersion + high efficiency + detail + coherence in a speaker?

I like the JBL recommendation so far.

regarding ATC - wonderful speakers but they come to life only at high volumes.

the efficiency thing is about immediacy! That is the magical word that is important in HiFi !

Coherence and dispersion = Revel. But not efficiency. Efficiency plus coherence maybe Goldenear Triton; anything with the powered woofer (3+ and up). No efficient speaker with coherence and dispersion comes to my mind. Zu may be efficient and quasi single driver coherent but forget dispersion. And frequency response curve is a deal breaker for me. Good luck. If you find a real answer lemme know.

Like previously noted…Klipsch Heresy III…el disperso a mundo.

The Hereseys are a bargain when you look at what $1800 buys these days.   Big soundstage , huge dynamics,  very good imaging, tight bass , clear and clean sound regardless of volume.  Feed them a good source with a good amp and they are hard to beat.

Too bad they aren't held in high regard by most "audiophiles"  , many of which I doubt have even heard them.

hi, have you found your prospective speaker candidate ? 
i think all of the suggestion are good but the best which are not suggested here are from Green Mountain Audio range of speakers. It haves time & phase coherent alignment speakers. Please researched their site. their R&D had paid off and proven in their speakers as among TOTL with lesser trade off, however i do not know their pricing but it's not over valued either. perhaps anyone whom may know the cost would give a estimate please. i'm interest too. 

@charles1dad  
do you still have the Coincident speakers which are coin by manufacturer as time and phase electrically coherent speakers, may i ask what is your opinion about their performance as compare to others which you may heard it before ? i heard their top model years ago, but its cost prohibitive for me! : (  so i wonder if their lower range with usual contemporary drivers setup would also "align" the sound well too?
