Notice you have nothing more to say about amplifiers?See the link to my response about amplifiers. As for the rest of your response, There are numerous holes in your response, but I do not have to time wade through copious reams of conjecture and pontification, so would not bother. On the Kevlar issue you are barking down the wrong tree, the new 800 series clearly attests to that, there were some issues with old design, but they did not arise as result of the use of Kevlar.

From Wikipedia.com:para-aramid fibers such as Kevlar and Twaron, which have a slightly different molecular structure, also provide outstanding strength-to-weight properties, and have high tenacity, and high Young's modulus.
Young's Modulus: http://en.wikipedia.org/wiki/Young's_modulus
As you can see most plastics have a low Young's modulus.
Here is a website talking about why Kevlar is so strong. It is exactly what I told you about crystallinity.
http://www.lbl.gov/MicroWorlds/Kevlar/KevlarPutting.html
All stiff crystalline materials have a high Q and of course the stiffer the higher the resonance will be in frequency (for things of the same size and thickness) and likely the more severe the problems.
Now since B&W admits it is operating their midrange in breakup mode and its a stiff fiber then how can you argue that its not a problem? Apparently B&W tries to damp it a bit but it is still there nonetheless.
"the new 800 series clearly attests "Is that so?? There are some comments in this thread by those who have heard the D series who have heard otherwise. I will have to hear them but what I expect is better driver integration (because of the shallow tweeter xover slope) but still the same overly dry mids that irritate rather quickly.
"There are numerous holes in your response, but I do not have to time wade through copious reams of conjecture and pontification, so would not bother"
There are not copious reams of arguments. In fact the argument is very simple. The Kevlar driver flaps and the self noise from the Kevlar flexing makes objectionable sounds. That is all there is to it.
Once again, you claim there are holes and prove nothing. You claim conjecture because you don't understand the argument. Typical non-sense you cover your own lack of understanding by "I don't bother". Yet look how much you have posted saying the same thing. So obviously you have bothered but what is disturbing is that you have ZERO to add to the discussion beyond "its not the Kevlar". Show me you are right, I respond just fine to evidence.
"See the link to my response about amplifiers"
I read it and already debunked it with Stereophile's measurements of this amp showing that into 2 ohms it delivers nearly 700 watts and into 4 ohms almost 1000 watts. Not only that but neverenoughmusic has 2 of these monsters on EACH channel. This means one of the amps is free to drive only the mids and tweeter (overkill power if ever I have seen it) and one for the bass, which is the most difficult part to drive, not the mids as you claim...bass energy and a large current hungry motor require MUCH more current than the midrange...sorry you are wrong again. You really don't understand loudspeakers very well, do you? If this is not enough clean power to drive this speaker properly then what is?? The Hoover Dam? Really you are ridiculous.
