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


And coherence is the biggest point! I like the liveliness of single driver speakers but I am looking for something with coherence AND bass! High efficiency is important for liveliness, and wide dispersion for a huge sweet spot and instruments in the room presentation.

Any recommendations?

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.

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?
