Blindfold Speaker testing

The idea of a true blind test is just a hypothetical; it is not something that could be implemented for gleaning any meaningful information.  Just on speaker setup alone, it takes MANY hours just to set up one pair of speakers, and movement of just an inch or two can result in major changes in sound (if one is moving into or out of a node).  There really can be only one pair sitting in an "ideal" spot.  Also,  speakers interact with each other so that the sound of one pair in a room is quite different from that with many other pairs in the room.  There are a host of other issues that make this sort of comparison problematic.  

Since you believe that one can make comparisons by viewing youtube videos, why don't you do videos (dark of course, so their is no image) with each speaker set up ideally in the same room?  That way each viewer can spend as much time on each blind video as the listener want to hear and the listener can make a choice when comfortable with his or her judgment.  You can then compile the results of preferences.  That way we will have some sort of valid information--which speaker sounds best when heard as a crappy youtube video.  

All I am trying to get across is the idea
High sens wide band 
sound completely, totally different voicing 
vs
xover designs.
Thats all I am saying here.
Line up 10 xover and 1 wide band. 
Anyone with even a  moderate sensibility to  audiophile  quality spaekers, will be able to detect which of the 1  speakes is the wide band/high sensitivity. 
That is my point. 
I am not at all saying the 10 xover designs are not audiophile quality, just saying the voicing is completely different in the midrange, 1500khz - 6k hz

Voicing implies intent and there is very little intent in that regard. The driver manufacturers are designing to specific parameters. The final loudspeaker system designer may be trying to make the system sound a certain way but in very few instances do the modify the driver. And, in most instances they are not listening to the loudspeaker, they are measuring it. Competent designers know how to juggle measured parameters t make a speaker sound a certain way within the limitations of the design. Full range dynamic drivers have some severe limitations that will keep them from producing the results one can get with a multi driver system. Just a fact of life. This is why manufacturers who are intent on making SOTA loudspeaker do not use full range drivers with the exception of ESLs.
