Does Time alignment and Phase coherency make for a better loudspeaker?

@rooze  I wonder if the Evolution Acoustics MM3s which have a family resemblence to Dunlavy Vs have similar time alignment.  Does anyone know?

Despite the truly great sound emanating from Dunlavy's, I cannot tolerate single point/seat listening.  Sure, it's great for me, but not for my wife and my friends who sit across a 10 foot couch.   I am looking at speakers more like Von Schweikert's which have a very broad listening/seating area for tonal equality many feet in width.  My wife hated the Monolith IIIs in 1997 prior to my getting Legacy Focuses and double pair of Hallographs.  

mijostyn  Right you are!  My custom built listening room has highly damped side walls and ceiling with all 3/4" cherry plywood walls (besides the SR HFTs & internal wall bass traps of activated charcoal chambers, etc.) and is only 19' X 15' X 10'.   

My family room is also nearly all wood but drywall finished 30' X 18' X 19'.  It has very significant reverb.  Talking comprehension across the room is especially difficult although listening to music and speech from long wall TV with separate audio is quite clear (speakers close to the wooden floor).  I wouldn't want to trade rooms for music listening.  My wife and I have to speak very loudly to be heard across the room.  The live room with high ceilings seem to blanket sound at a distance.
