Polyglass membrane
Well-defined mids
The cone, the centerpiece of a loudspeaker, is at the heart of our acoustic engineers' research. Focal's exclusive Polyglass technology involves applying fine glass microbeads to a cellulose pulp cone. This process combines the excellent damping of paper with the rigidity of glass. The rigidity index is almost 10 times higher than that of polypropylene. Adjusting the mass-rigidity-damping ratio results in a remarkable linearity of the frequency response curve, right from the cone design stage. This innovation also significantly increases definition in the midrange.
