How do Cerasonar loudspeakers work?

The construction of cerasonar DML loudspeakers is special, even though the technology has been known since the 1930s. In contrast to conventional loudspeakers, the surface of the cerasonar flat panel loudspeakers does not move like a piston, but oscillates microscopically over the entire surface with a maximum excursion of only 0.3 mm (Distributed Mode Loudspeaker). Imagine the panel being made up of thousands of tiny acoustic drivers, busy reproducing every single musical note evenly distributed across the entire panel. Compared to cone loudspeakers, cerasonic DML panels radiate the entire frequency range almost uniformly at an angle of more than 170° both horizontally and vertically. Since the sound pressure does not decrease with distance as with conventional loudspeaker systems, the even sound distribution over the entire audible range offers a truly unique stereo experience.

The basis

The invisible loudspeakers from cerasonar are built with the advantages of good loudspeaker membranes in mind. Our founder, Ulrich Ranke, introduced the design of the patented ETON Hexacone membrane (manufactured in the 1980s) into the development of the cerasonar panels with a very stiff, light and yet well damped sound surface.
Completely without crossover components, the Cerasonar loudspeakers achieve a very balanced sound range. This is particularly noticeable in the case of more complex musical materials such as classical or rock music, but also overall through natural sound reproduction.

Our own technology

In mid-2006, we began development of the Cerasonar Exciter, the motor system and a high-performance panel model. In 2010 we released our XT 5500 FF37 Exciter and filed a patent application for the “MCC” (Mode Control Correction) system. This special technology ensures a natural sound through the correct attenuation of mode interference. A big step towards ensuring premium sound quality.
