@shadorne I think you are right about the sandwiched ceramic drivers, the new Revel Performa3Be speakers are quite low in sensitivity, officially rated at 86db. I bought one a pair of M126Be however I noticed they need noticeably more more power than other similarly low sensitivity speakers.
What do you think is better, pure ceramic or beryllium for a midrange? From what I understand, beryllium is a metal that bends, but is also isn’t internally well damped, wouldn’t it have a similarly splashy sound to a pure ceramic driver? What is the materials science reason behind both hard (ceramic) drivers and beryllium (a metal that bends) both having internal damping issues?
And what would you consider your ideal midrange driver material?
