are magico better than electrostatic

magico speakers do not eliminate rear wave energy. They contain it inside a box where it bounces around and much of it comes out the cone. Also being a multi way speaker it splits the signal up into parts then tries to combine them again. This is never going to be as good as having a driver that can actually produce full range perfectly, which currently doesn't exist.

So how good really is magico? how would it compare with the perfect speaker if it existed? 

what makes a magico that much better than an average speaker such as ATC?
