Magnets for sound systems
The sound system industry is always looking to improve the quality of acoustics and product performance, coming up with smaller and smaller appliances. Few people know that magnets lie at the heart of the sound system, therefore they must be given their due importance.
This is why we have developed this product line that includes magnets and magnetic assemblies.
In the past, powders and technologies were used to create magnets that provided results with scant quality and sound power, the magnets were large and heavy and it was difficult to adapt the shape of the magnets to individual requirements, giving rise to similar products that all had the same mass. Today, thanks to the new mixtures of powders and advanced manufacturing technologies and especially the possibility to control the magnetic flux, it is now possible to guarantee particular shapes and Gauss values that are especially calibrated for specific applications.
