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?

++1 mapman! I have a pair of the older Walsh Sound Cylinders (with the 8 inch drivers). In use for 10 + years now! They do indeed sound AMAZING - a wide open 3D sound from anywhere in the room!
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.
