Good Question!
The Noblesse is very efficient at 95 db. It obviously looks different than the bending wave speakers and it plays louder. I don't have my head totally wrapped around the difference in sound yet since I just got it yesterday however it is very good and my initial reaction is this is a product that is going to shock the owners of Wilson, Magico, Focal etc. They can be used with almost any quality amp since they are super efficient and are a very easy load to drive. There is a lot of technology in the midrange drivers that comes from the Bending Wave so they are very open, really fast and throw a huge stage. They are beautifully finished in the same Grand Piano Lacquer that we use on all our speakers and are fully assembled and come packed in flight cases. They handle loads of power and can play very loud as well. They are once unpacked relatively easy to move around since they also come with customs sliders and once in place they rest on Oliver's cool ceramic ball bearing footers that are easy to adjust to get the height and to level. I spent some time last evening late after everyone was gone playing with them and I am thrilled with the sound even with just a few hours of playing time and very little adjustment.
