Diapason Adamantes III Speakers

Made in Italy

These speakers are super open, and a lot of fun to listen to.


Speaker-shape design was especially realized in order to match astonishing and realistic sound performance with Italian cabinet craftsmanship. This makes each speaker a unique and precious piece-of-art.
Full wood cabinet is engraved standing out multifaceted front and rear baffles in order to provide a circular emission of sound waves around the loudspeaker and to give a close approximation to the theoretical ideal of point-source radiation.
Sound performance is impressive in terms of 3-dimensional feeling: the loudspeaker quite simply ‘disappears’ from the scene, giving the listener the sensation of a highly realistic ‘virtual’ soundstage.

Closer to cabinet shape study of the Diapason flagship Astera, the front multifaceted panel of the Adamantes III 25th is provided with different angles compared to previous version Adamantes III, improving drivers emission and allowing more cabinet thickness. As a result of this improvement sound performance is considerably rich of harmonics , more controlled in cabinet resonances and capable to give realistic emotional feeling close to live musical events.
