No dynamic tweeter not even an Accuton Diamond tweeter can match the Magneplanar ribbon.
Mozartfan, those specs only tell you how you can use the tweeter. They tell you absolutely nothing about how it sounds and works in a room. The problem with most tweeters is that they spray high end all over the place worsening room interaction. This plays havoc with correct imaging and tends to increase sibilance. The Magneplanar ribbon and ESLs do not do this and even if you boost the treble sibilance is absent. Dipoles do not send any energy to the sides minimizing reflections off of side walls, line sources have the added advantage of not radiating either up or down.
Next time you are in the presence of a dipole walk around it and see what happens.
