Diamond Coatings for Speakers, IEMs, and Headphones

This article explores a fascinating topic that is recurrent in the loudspeaker industry: diamond coatings. As speaker designers look to refine their products' sound quality through diaphragm treatments, there are benefits to be explored from diamond coatings, or more specifically diamond-like-coatings (DLC), which is a process that matured over the last half-century. The industry has now reached a stage where this technology becomes available and viable, particularly for microspeakers.

After 25 years of designing, crafting and manufacturing high-end audio components, the founders of Audia Flight in Italy couldn't resist the temptation to design their own speakers. Following an original design created for testing their own audio amplifier circuits, which after ten years remains in use in their lab, the company decided it was time to create a new high end loudspeaker brand, Alare. And the company introduced Remiga 2, their first product now available.

The samples for this Test Bench came from respected German home/car audio OEM transducer manufacturer Accuton. I received the Accuton C30-6-358, its new “Cell Concept” neodymium motor ceramic diaphragm 30 mm tweeter. The Accuton C30-6-358 is an interesting tweeter for several reasons. The mounting system, which is part of the “Cell Concept,” is definitely unique, with its proprietary clapping mechanism. This article was originally published in Voice Coil, April 2017.
