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

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?

Hi Phil,
I have the Coincident Total Eclipse II which are no longer in product.  I've own them for over 9 years and my happiness with them if anything has grown. It has a simple 1st order crossover and to my knowledge is phase and time coherent. 

This speaker is very open, lively and quite emotionally involving.  Excellent natural tone and exceptionally dynamic(similar to a high quality horn speaker). High resolution but isn't a uber detail type of speaker. Definitely is not clinical or analytical. Overall  summary,  natural, organic presentation and an easy to drive impedance load.

I have no reason to replace this speaker other  if I were forced to use a smaller room. Other than that I have no desire for change. Other speakers I believe that I would also enjoy just for comparison.
