Polyglass technology, exclusive to Focal, consists of applying fine glass microbeads to a cellulose pulp cone.
EXCELLENT DAMPING
This process combines the excellent damping of paper with the rigidity of glass. The stiffness index even exceeds that of single-skin Kevlar® and is almost 10 times greater than that of polypropylene.
WELL-DEFINED MID-RANGES
Adjusting the mass-rigidity-damping ratio results in a remarkably linear frequency response curve, right from the membrane design stage. This innovation also significantly increases definition in the midrange register.

PRISM
Mastering high frequencies
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.
