Performance and musicality

Since its introduction, the Black Swan has been our reference screen channel speaker. As research-based company computer-based models are the basis for our work. The modeling capabilities improved significantly over the past years which we used to revisit the design for the waveguide. Small improvements have been made, which lead to even better homogeneity in horizontal and vertical dispersion over the desired coverage. Also, the low-mid section has received an improved design to bring waveguide and woofer even closer together as point source.

The Black Swan Beryllium is an impressive and extraordinary performing musical speaker system, that leaves nothing to be desired.


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.

You must be wondering, what does all this mean to me as a user?

It means, that even the finest details are all there.

It must be experienced to be believed."

"ASCENDO's proprietary DSP technology works in combination with the enclosure and coaxial driver design to deliver ultra-precise and incredibly fast impulse response. Each Black Swan channel is capable of incredible SPL levels, but also the more impressive dynamic contrasts from whispering dialogues to explosive effects. The volume ranges your home theatre speakers needs to be able to handle without audible distortion is huge, especially if you look for a reference level director’s cut performance - this level difference from softest to loudest sounds is called ‘dynamic range’. The Black Swan reproduces every possible dynamic range with ease. Even the most complex film passages with extreme dynamic requirements are reproduced at the highest clarity and lowest distortion. Imagine a life-like drum solo rendered exactly to the point by hearing and feeling the tremendous dynamic leaps of a bass drum and snare, while at the same time the humming of the cymbals fading away airily into the dark silence of the room giving way to the tiniest fine details. 

This very precision lets the listener immerse entirely into the direct and intense visual action. Whether film or music – this sonic experience is not distinguishable from reality anymore.

The expertly engineered 4” Beryllium mid-high unit is arranged next to the 15-inch mid-woofer unit, both drivers are driven by a DSP-controlled two-channel digital amplifier. Their results merge perfectly and allow for a time and phase-coherent lifelike reproduction of all acoustic events with reference level in every seat. The brain can therefore relax and stop trying to process the timing and phase errors far too common in other speaker designs. Advanced audio-over-IP technology and a sophisticated system user interface to control every function provide an unprecedented level of control and flexibility to the calibrator.

Combined with our SMS Reference subwoofers you will experience unimaginable realism of sound paired with sheer limitless dynamics.
