I've heard several things regarding driver size that I just wanted to check on. 1) that if the driver's not large enough, it cannot accurately reproduce human voice. Is this true? 2) Also, I'm interested in Axiom M22ti's and have heard Paradigm Monitor 5's and Studio 40's may be somewhat comparable. But, I can't help but notice that Paradigm drivers are 6.5 inches or 7 inches (monitor 5 and studio 40 respectively) and the Axiom speakers are only 5.25 inches... does this matter? please refrain from any driver-envy jokes.
