PRISM
The future of treble
PRISM technology is a major innovation in the mastery of high frequencies. By combining a multi-material substrate with an advanced micro-structuring process, it makes it possible to harness the full potential of each material and achieve stiffness superior to that of beryllium, while preserving a perfect balance between lightness, damping, and rigidity. The result of several years of research, patented and manufactured in France, PRISM sculpts membranes with unprecedented precision.
