ESSENTIAL SPEAKERS
BUILDING BETTER SPEAKERS Florian Marmisse, Junior Electroacoustic Engineer with Sonus faber, gives EI a behind the scenses look at how the company designs and creates its speakers, overseen by Mario Passarelli (R&D Manager).
The mix of new technologies/simulations/experiments and knowledge is the basis of how to design the high-end audio product in the Sonus faber R&D department.
The 20 years of loudspeaker design from Mario Passarelli (R&D Manager) allows design efficient drivers, from the first coil wiring to the shore of the surround. His knowledge allows Sonus faber to start every project with a good and solid basis : the loudspeaker.
Once designed and produced, using KLIPPEL Analyser, the acoustic team can understand the physical behavior of the driver and its limits. DC Offset? Non symmetrical force factor or stiffness? Distortion? Compression? Nothing escape Mario’s watchful eye.

Then, thanks to F.E.M. simulations, electroacoustic engineers can proceed of the optimisation of the loudspeaker. Motor non linearity optimisation, Spider and surround shape design, turbulences of reflex ports are among other what can be improved with the help COMSOL Multiphysics software.
