Ascendo The15 Be PRO Active EXT On Wall
The THE15 Be PRO ACTIVE EXT ON WALL requires a high quality powerful 2ch DSP controlled amplifier. The 15 Be PRO ACTIVE EXT ON WALL is an extremely impressive and extraordinary performing musical speaker system, that leaves nothing to be desired.
This 15″point source axisymmetric speaker has been designed as screen speaker for large theaters as left, center and right speaker or can be used for very large theaters as a surround speaker.
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.
