From Ex3ma, Il Cremonese ex3me inherits the Beryllium DLC (Diamond Like Carbon) tweeter.
Sonus faber set aside its classic silk diaphragm Damped Apex Dome™ tweeter to approach this transducer construction.
Brilliant in terms of transparency and micro dynamics, the Beryllium tweeter diaphragm has formidable physical characteristics but it has a sound presentation often described as a “metallic flavor” which can often make listening unpleasant.

To mitigate this typical Beryllium characteristic we used a treatment called “Chemical Vapor Deposition“. A layer of D.L.C. is deposited on the diaphragm surface, turning it black and giving the Beryllium some of the typical properties of diamond— the most important being its amorphous nature and unmatched strength.

As a result, the new diaphragm is increasingly rigid with a nearly unperceivable higher resonant frequency, making it capable of extremely fast sound, very detailed and airy – free of coloration.
