ISOPHON Berlina RC 7 MK II diamond tweeter
The Innovative Cabinet Structure Responsible for the natural, transparent sound of the BERLINA RC 7 is the new horizontal rib construction of the cabinet. It eliminates sound coloration and cabinet vibrations. In contradiction to the classical construction method no boards are glued together but 38 mm thick moulded pieces of wood which show the shape of a rib are aligned one over the other and then screwed together. To eliminate vibration spreading there are 3 mm thick soft-fibre ribs coated with silicone between each two ribs which dampen sound spreading. All the ribs have a special shape and varying thickness to cut off resoances in them.There are also some ribs which are additionally stiffened by a cross between them. All in all there are eight different ribs all of them having a special task to fulfill. The bottom rib carries integrated spikes for leveling and height adjusting. In extensive tests and measurements we have had many single parameters in focus which are responsible for sound coloration, like e.g. cabinet material, wall thickness, geometry, internal dampening, stiffening, wall dampening, damping material etc.The RC 7 now is the essence of all these research efforts. All the mentioned parameters are in perfect balance a cabinet so ingenious like never before in HiFi.You do not need to have a perfectly equipped studio for the BERLINA RC 7. It was developed under listening conditions like in typical living-rooms. Especially the bass response is strongly influenced by the room acoustics. Therefore the RC 7 owns our unique triple room-equalization system. By plugging in or out a gold-plated bridge in one of the three positions the bass response can be adjusted to adapt the RC 7 to your room or your taste of reproduction (-1.5 dB, linear response, + 1.5 dB). So the room influences are reduced and you can concentrate on music and get caught by its fascination. The BERLINA RC 7 uses high-quality WBT-single-wiring connectors. On request it is also available in bi-wiringtechnique. |

Loudspeakers have become part of our furnishing, part of the interior environment. The BERLINA RC 7 can be integrated into any living-room furnishing due to its dynamical design, the well-balanced proportions and the beautiful outlook and finish in genuine high-gloss piano finish. black or white.Technical solutions for important details, e.g. the adjustable spikes, are harmonically integrated into the bottom rib.A BERLINA is more than just a loudspeaker, a BERLINA is the dream of esthetics, class and musical definition.The Crossovers of the BERLINA RC 7 With separate crossovers for bass and the mid-high-frequency range and a totally isolated chamber inside the cabinet for it the BERLINA RC 7 additionally sets new standards in loudspeaker design. Moreover, this chamber is vented by a slit at the bottom and one at the back just beneath the terminal to keep the crossover working thermally stable. As the first speaker in the world the BERLINA RC 7 uses a totally symmetrical crossover circuitry with a slope of more than 50 dB/octave. This all leads to a music reproduction which is almost free of distortions and dynamical compres-sion effects so as to keep music authentic and joyful for any listener.Hint: Even played low the BERLINA RC 7 sounds warm, strong and full of details like you have never it before from other loudspeakers. Hidden Values For Great Sound BERLINA RC7 BERLINA RC 7 from beneath: You can see the adjustable spikes, the two bassreflex vents and the frequency crossover in its separate chamber. The blue channel provides heat exchange.
