Speakers as the principle component/other components are servants

Speakers  hold the Kingship in our overall  audio systems. 
I think my recent posts have substaniated  this thesis, well at least my opinion of sorts.
This OP  came to me after reading  through some of (most of what is too deep for my understanding) 
pedro's 
topic
**Why is science a  starting point, yet not the end point?*
Meaning science gives us all sorts of parimeters, specs, graphs and such. Most of which we have no clue how to interpret, 
All we ae concerned is , **how does the speaker actually sound**.

Pedro suggests science has let us down, that science, if it was so intelligent, why can't science tell us which speaker is the superior and which the inferior sound???
Obvioulsy science is not the end all /be all.
Its only a  tool, human sensibilities come in  at the very end to say
Yea 
or worse
Nay
I say nay
to all/eversy xover design in the fq's ,,ohh say 800hz = 15khz.
Yeah I know thats a  massive chuck of our music.
As many of you know i make very long winded posts 
But actually I reduce them to make them more readable and so folks don't lose  interest. 
~~~So cut to the chase.
We accept high tech in every aspect of our lives.
You name it, super high tech is there,. Had you told us back in 1965, folks would be walking around with telephones, sending pics/videos,,we'd all laugh you at your face  as scifi fantasy.

~~~Long story short.

The new  wide band /high sensitivity speaker technology. What gives?
Why the denial it exists?
Why the fear to inquisite?
Why the lack of interest?
Why the rejection?

Speakers  will crown your system with beauty Or else render it as distortion/low fidelity.

Tweak/,od/upgrade all you want, at how much you care to spend $$$$$ ($40K!!!) on cables etc. 
Ain;'t going to make hardly even a  miniscle gain in sonics, if the speakers are ~~faulty~~  due to  low sensitivity.
Bass woofers, I'll grant low sens Seas and Scaspeaks high end woofers  a  stunning succcess.
Above 800hz,  I have issues with any driver neededing a  xover.
I tag these fq's with xovers. The Wet Blanket sound. Sounds mechanical, like   compressed music,, comming from a  box.
Squeezed, contorted, tiny soundstage, strained fq's  if vol is over 10 oclock. = fatigue/Coloration  in abundance.  
Many fq's of the source, missing in action. 
I am not suggesting  these new wide band is for everyones taste. Not at all. Only that we should at least give these wide band a   consideration as a  possible alternative to our old  traditional ideas.

Inqusisitiveness is a good thing in  all things audio. 
Without  a  healthy  curiousity, we putrefy , stagnate.
 Even  Worse
we might miss out on the super high fidelty we all hope to hear one day in our systems by this neglect  of the new high technology in speaker design. .
