... sinceramente, soh fui reparar essa spec lendo esse post ... uma pessoa que pode dar um opniao concreta sobre essa "evolucao ???" eh o andry, vamos esperar que logo ele aparece para comentar algo.
... duas opnioes lidas na internet :
"I know that there is a general feeling that Mylar and plastic diaphragms sound better because the metal ones have very low damping of some of the higher Freq resonances. The plastic diapragms have resonances lower in freq, but are far better damped."
"Titanium is very light, light as aluminium and strong as steel.
That is why it is used, the result is very low weight for the necessary domestrength.
Titanium also has a very high soundspeed which means that it is easy to dampen it, even if it never is done in commercial units.
But with dampening it will sound very good all the way up to atleast 12-15KHz for a "normal" 1inch horn.
That razorsound you describe is either reflections within the diagraphm or reflections within the hornpath.
Without those reflections then titanium is in my experience the best choice above midrange too.
-However, i am not a fan of titanium domes with mylar surrounds that is used in some drivers from RCF for instance"
