The structure of the FAL flat unit is a thick-walled die-cast aluminum frame with a large neodymium magnet.
The diaphragm is made of lightweight and highly rigid Styrofoam (with reinforcing ribs) with papyrus on the surface, and the voice coil bobbin is made by DuPont, France.
The edge is made of Toray's Exaine double edge, and even if it is soft, it is strong and drives the diaphragm firmly, achieving both linearity, high efficiency, and high durability.
The voice coil bobbin is a rectangular shape that matches the diaphragm, with double silver wires wound on the outside and inside, and a neodymium magnet magnetic circuit sandwiches the voice coil.
