Dipole with coaxial ribbon system

MasterONE

A full sound that is nevertheless crystal clear and lively, even at low levels, an outstanding pulse response, full-bodied – these are the excellent sound qualities of the MasterONE. It is also the only dipole that has no major requirements in terms of installation and can be integrated in the room like a normal loudspeaker.

PIEGA's MasterONE sets a further milestone in the history of loudspeaker development. For the first time, it has been possible to combine in a dipole system the uniqueness of the coaxial ribbon system and the essential design elements of slim-line column loudspeakers. Unlike conventional large-size electrostatic panel loudspeakers, the coaxial ribbon system operates solely as a single point sound source. Compared to panel speakers, this has the advantage that the loudspeaker has a single acoustic center, and placing fewer requirements in terms of room conditions when it is positioned.

The new MasterONE can fill even large rooms with sound, offering outstanding performance with a virtually perfect pulse response which is not “shrouded” by the components of the indirect sound. The resulting resolution is of a clarity that was previously unknown, without any additional effects. The MasterONE is provided with the PIEGA coaxial ribbon system, in which the light-as-a-feather membrane of the tweeter is surrounded by the membrane of the midrange. The specially designed bass cabinet offers an extraordinarily large net volume in relation to the small dimensions and specially tuned 22cm MOM bass chassis (Magnetic Optimized Motor) ensure a full-bodied low bass range. This presented the greatest challenge when the cabinet was manufactured, and involved the development of new techniques and approaches. The baffle is made from a solid aluminum block and a core with high damping properties. A 7000 ton press is used to press the individual cabinet sections from a three ton aluminum block, and the bass cabinet consists of aluminum plates that are laser welded with total precision. The sophisticated damping made from bituminized composite material prevents any kind of resonance. Thanks to all these progressive production processes we were able to produce the acoustically perfect housing.

As to be expected from PIEGA, the visual appearance of the loudspeaker is characterized by the wonderful timeless elegance typical of the Hannes Wettstein studio. The polished aluminum cabinet of the baffle and the attractive ripple finish of the bass cabinet suit any surrounding and reflect perfection impressively.
