THE MASSIVE ALUMINUM SERIES

DARC – END OF ALL DISCUSSIONS


It is a well-known fact that the use of aluminum as a loudspeaker cabinet material causes different problems. Especially the “Ringing Bell”-effect is a killer criterion. There have been many attempts to overcome this problem by extreme bracing, wall damping by bitumen coating or covering by wooden materials. Actually the big problems could never be eliminated fully. With our Berlina RC (Rib Construc­tion) series we could show the positive effects of dividing a cabinet wall into segments with dampers in between them. Applying this technology to aluminum ribs really brought the breakthrough! None of the disturbing effects of conventional aluminum enclosures could be found. The perfect cabinet was born!

To set new standards in Home-HiFi music reproduction we equipped all DARC loudspeakers with the finest loudspeaker components available. Latest technologies of ultrasteep filtering with more than 60dB/octave are separating the frequencies in the crossovers on a new level of loudspeaker design. To setup the DARCs to your room they also have a fine-tuned 9-fold room equalization system and the bass extension jumper for adapting them to single-ended triode amplifiers. The DARCs – real loudspeakers for life!

The “Double Vison” version adds finest nuances of instruments and voices to all series products by the use of special inner components.

TECHNICAL DETAILS:
· symmetrized crossover with Mundorf parts
· ultrahigh slope crossover of 60 db/octave
· Black Accuton or Gauder Akustik woofers
· Accuton mid/high drivers
· 9-fold room equalization system
· Bass extension jumper
· WBT NextGen binding posts
· Adjustable Spikes included
· Big foot available
· Double Vision version possible

Cabinets are built up of massive aluminium ribs

  Aluminum has very good properties as a material for loudspeaker cabinets like stiffness, hardness, rigidity and high mass density (compared to MDF wood). Unfortunately these properties lead to negligible inner damping so that normally built cabinets ( squared sidewalls,..) ring like a bell when they are excited by drive-units screwed to them. Therefore long time it was very critical to use it.

By applying the concept of rib construction like we show in our Berlina series we can totally eliminate this big disadvantage. In the RC (Rib Construction)-concept massive 40 mm high ribs are stacked one over the other with high damping fibre-material ribs between them thus creating an acoustically perfect cabinet which shows no resonances or any other influences on the reproduced music.

Symmetrical frequency crossovers of ultra-high slope (> 60 dB/Octave)

  Every multi-way loudspeaker need a frequency crossover to direct the correct frequencies to their drive-unit.  Unfortunately crossovers have a finite slope (e.g. 6 dB/Octave) so that there is a big crosstalk between the drive-units. This leads to coloration, loss of information (phase) and bad transient response.

With our very steep crossover filters this overlap problem is solved totally. Additionally as the single drive-units get only their frequencies the power capability is much higher and you cannot destroy midrange or tweeters in our loudspeaker systems.

Choosing only best components

  Creating such elaborate crossovers only makes sense when also using perfect crossover components and connectors. To ensure best performance we only use crossover components from Mundorf and IT and binding posts from WBT.   GAUDER AKUSTIK WBT  

 

Aluminum, ceramic and diamond drive-units

  Music is not consisting of long-lasting sine tones but of single, high-dynamic transients. Therefore it makes perfect sense to take care of the impuls response of a loudspeaker. It even seems that impulse response is more important than a perfect frequency response. So only light, stiff and rigid diaphragms made of aluminium, ceramic or diamond can ensure this.

Many people think hard materials sound hard. This is completely wrong. Diaphragms made out of these materials can lossless follow the music impulses and therefore they do not create artificial signals like soft materials do. They just have hard resonances out of the passband so you need to use very steep filters to cut off these resonances like we do with our 60-dB-filters!

Many manufacturers have a philosophy in what they do. Actually the truth lies in the music and so you should not take into account philosophies, technical data or any statements done. Just listen to the speakers! The only thing that counts is the sound of the speaker! Is it natural? Do they show the space and the stage of the recording? Are the impulses hard and precise like in reality? Do you have the perfect illusion? Is the band standing right in front of you when you close your eyes?
So forget about brochures or technical specs – just listen!
