FAL flat unit structure attaches large neodium magnet to thick aluminum die cast frame
The vibration plate is lightweight, high rigidity styrofoam (with reinforced ribs), papyrus on the surface, voice coil bobbin is made by DuPont, France
The edges are double-edged with Toray Exène and are soft but strong, driving the vibration plate firmly, achieving both linearity, high efficiency and high durability.
The voice coil bobbin is a rectangle tailored to the vibration board, and the silver wire is coiled double on the outside and inside, and the magnetic circuit of the neodium magnet seems to be stiff between the voice coil.
