Ken, this is part of what Alan told me when I asked him "what constitutes a 2 1/2 way design vs 2 or 3 way?"

"....In a "2 1/2 way design, one of the two woofers has a low pass filter (passes the lows and rolls off the highs) on it; the other woofer does not have a low pass filter on it so it is allowed to mechanically/acoustically roll off naturally....this design is used on the Axiom M50 tower speaker..."

Half of communication is listening. You can't listen with your mouth.
