Well-defined mids
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.
