Diapason

The Prelude, and all the speakers manufactured by Diapason, are designed to offer the highest fidelity and transparency to the absolute sound. Furthermore, our speakers convey the emotional involvement of the live performance.
Each Diapason speaker is hand assembled and wired by skilled craftsmen. The beautiful cabinetry is not only an integral part of the design, but the highest example of Italian furniture- making. The cabinets, which are constructed in solid-wood staves and completely handmade by our skilled craftsmen, are assembled in a particular way which makes the whole structure highly rigid and free from resonance.

INNOVATIVE DESIGN
The shape of this multi-faceted cabinet makes it possible to obtain circular sound emission from the drivers. The speaker recedes from the soundstage and the listener just hears the music, with all the features of a live event. The numerically-controlled techniques used for the curves on the front and back panels of the cabinet make acoustic dispersion around the speaker even more effective. Three-dimensionality, detail and the realism of the soundstage where the listener is immersed all improve.
FOCUSING ON THE MUSIC
The multi-faceted shape of the Ástera model has been designed to obtain optimal acoustic dispersion and enable the circular emission of the sound waves around the speaker, achieving as ideal a point source as possible.
QUALITY MATERIALS
Select SEAS-manufactured drivers, silk dome tweeters, paper cone woofers and cabinets made of aged wood achieve the best sound reproduction rich with harmonics, perceived as balanced musicality by the human ear.
THE COMPONENTS
Crossovers and transducers in each Diapason design are the result of advanced technological research and are tested individually and in combination, with tolerance levels of 1% to obtain the best performance. The tweeter has a soft silk 29-mm dome and a magnetic Hexadym system that incorporates a dual damping and ventilation system.
The woofer has a Nextel-coated paper cone and metal basket. Crossover circuits are wired directly using oxygen-free copper and silver Van den Hul cables, avoiding the unwanted effects of printed circuits.
PURE ACOUSTICS
The sound reproduced is completely natural, transparent, three-dimensional and full of detail. The performance of the Ástera model is astounding in terms of musical impact, not to mention its ability to enhance and contrast instruments in the surrounding space with incredible clarity and a focus on the instruments themselves.
DEDICATED STAND
The 4/U support stand has 4 metal legs combined with solid wood side panels that integrate with the speaker aesthetics and make the structure more rigid, ensuring optimal speaker performance. Stands are 75 cm in height, with 4-cm spikes under the base to lift them off flooring, carpets or rugs.
