JohnK, I am definitely not an audiophile, I will leave the technical lingo to those better suited to explain it. Playing devils advocate here, if the dedicated midrange driver does absolutely nothing to improve the midrange dynamics than why does Axiom put them in the M60's. If they serve no purpose why not just leave them out and save all of us some money. The same goes for car stereo's. Why when you go to the shows and you look at the installs are there usually a woofer paired with a midrange driver and tweeter. Now we all know that a woofer can not produce what a tweeter can but it can produce midrange so why put in the extra speaker. I am not claiming that I am right I just feel that it is there for improved clarity.
