The True, Three-way Loudspeaker.Articulate and authoritative the Riva is a competent floorstander. Whatever the genre, whatever the medium, the resulting sonic picture is open, fluent and involving. Furthermore, the clean lines and smooth curves make these speakers a feature piece that you will be proud to display.
This midrange driver is paramount to the open sound picture the Riva portrays. Based on listening tests, the diaphragm is made from a blend of different pulp to obtain the desired balance of stiffness, damping and density. A small but precise amount of Egyptian papyrus fibers are added to make the membrane less isotropic and to further enhance the sonic charachter.
The Riva crossover is computer modelled to optimise driver integration and response accuracy, and then fine-tuned by ear to ensure naturalness and a musically rewarding listening experience. All components are carefully laid out to minimise electro-magnetic interactions, and the quality of the critical signal path is maintained by taking advantage of the minimal losses in polypropylene capacitors and the linearity of air-cored inductors.
For critical listening the grille is usually removed from the loudspeaker. By intergrating the grille into the design, this is no longer needed with the Riva. Only 3mm thick, the sound is not at all blocked anymore by the grille. By gluing it to the cabinet, it is furthermore no longer a potential source of resonance.
