Diapason was founded in 1987 by Alessandro Schiavi, who previously had extensive experience in recording studios. His skill in capturing live music in three dimensional space and its faithful reproduction, led to the development of the first speaker by Diapason, the Prelude.
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.
At the basis of every Diapason project is the study of form, whether in the search for an elegant and refined appearance or for innovative solutions in the quest for perfect acoustic reproduction. The Reference Series and Adamantes Limited Edition represent the pinnacle of this research, with its "diamond" form which enables the loudspeaker drive units to perform at their best. Their unique polyhedral shape eliminates all distorting resonances allowing the music to be heard without smear or bixiness.
The drive units and crossovers used in each Diapason project are the result of the most advanced acoustic research, and are matched to a tolerance of within 1%. Drive units are made exclusively by the best manufacturers to strict Diapason specifications. Only materials which have been thoroughly tested are used, to ensure the best acoustic performance and to allow ease of driving by any kind of amplifier.
In more than 10 years of advanced research and design Diapason has developed the system known as Diapason Direct Drive, which allows a direct connection between the amplifier and bass unit thereby eliminating the disadvantages of a low-pass filter, such as loss efficiency and phase rotation.
