Performance and musicality
Ascendo The Black Swan Be PRO Active EXT
The THE BLACK SWAN Be PRO ACTIVE EXT is an impressive and extraordinary performing musical speaker system, that leaves nothing to be desired.
Beryllium (Be)
Although it is one of the most expensive materials used to make speaker diaphragms, in terms of stiffness-to-weight ratio, Beryllium is the highest of any known metal and can deliver dramatically superior results when properly incorporated into a speaker design.
The speed of sound through Beryllium is nearly 2.5 times faster than the speed of sound through aluminum or titanium. This means the first breakup will occur at a much higher frequency — well outside the audible range. Breakup occurs when the cone partially vibrates at certain audible frequencies and therefore isn’t entirely pistonic throughout its range. This leads to non-linearities in the amplitude response as well as stored energy in the time domain. It is precisely these characteristics that give Beryllium speakers the ability to reproduce amazing detail and provide sound clarity with the absence of resonances.
