The structure of the FAL flat unit features a thick aluminum die-cast frame with a large neodymium magnet attached.
The diaphragm is made of lightweight, high-rigidity styrofoam (with reinforcing ribs) with a papyrus surface. The voice coil bobbin is made by DuPont in France.
The edge uses Toray's Exceine in a double-edge design, enabling soft yet strong support to firmly drive the diaphragm, achieving linearity, high efficiency, and durability.
The voice coil bobbin is rectangular to match the diaphragm, with double-wound silver wire on the outer and inner sides, and the magnetic circuit of the neodymium magnet sandwiches the voice coil in a meticulous design.
