Just curious why companies don't use CNT diaphragms more ? I see a few companies using this material ,but it seems not much research has been done for use in hps.. Is it because of the health risks involved in manufacturing or because it doesn't make a good driver material?

On a side note, is there any lists comparing different driver materials in iems or full size ( Mylar vs bio cellulose vs titanium etc.. ) thanks for any replies
