Unique worldwide: The symmetrical design.

In addition to the individual loudspeaker drivers and the cabinet, the crossover is the main factor responsible for the sound of a loudspeaker cabinet. The crossover controls the interaction of the individual loudspeaker drivers in a returnable box. It determines at which frequency the individual drivers are acoustically removed or from which frequency they are inserted.

This creates a more or less large overlap area in which both drivers work simultaneously, which leads to distortion and interference. The crossover is the heart of every loudspeaker and determines the dynamics, power handling, resolution, three-dimensionality, sharpness, transparency and naturalness of a loudspeaker cabinet.

Years ago we therefore developed a new, revolutionary concept that placed crossover technology on a new foundation and has been
is used exclusively.

Fantastic transparency through the combination of pioneering materials.

BERLINA RC 3 Frontside
1 whiteceramic - the material of the 21st century. Almost unrivalled even for loudspeaker membranes. Of course, that's why we also rely on it for the Berlina series. At least up to 1,000 Hz. Because after that, there's something even better: diamond, a material with surprising and astonishing properties. Diamond is the material with the greatest hardness (hardness 10).

A diamond diaphragm therefore behaves like an ideal piston even at much higher frequencies. This diaphragm can also withstand higher accelerations. The resolution of individual tones and pulses is unique. Even the smallest subtleties and details are still audible. Dynamic compression due to deformation is no longer possible. In addition, diamond is still the material with the highest sound velocity of all materials (18,000 m/s) and thus three times as high as titanium. This means that the dreaded partial oscillations within the membrane only occur at ultrasonic frequencies that are inaudible to humans. The diamond acts like a giant heat sink, as its thermal conductivity is more than five times higher than that of even the second best material, silver! So there can be no more effective cooling of the voice coil. The dynamic compression that often occurred in the past due to the heating of the voice coil and the resulting increase in resistance of the voice coil wire are a thing of the past.

BERLINA Diamond MTEs are therefore no wonder when one speaks of diamonds as the material of dreams par excellence. The material guarantees high resolution, full dynamics even during long periods of operation and freedom from discolouration. The best conditions for a fantastic loudspeaker! Diamond tweeters are standard on the BERLINA RC 9 and RC 11.

For the RC 3, RC 7 and the BERLINA FRC you can order diamond tweeters as an option. A subsequent upgrade is also possible at any later time.
