■Lightweight banana pulp cone / high-loss foam rubber edge
The cone paper is made from a banana pulp base mixed with two different wood pulp materials, resulting in a lightweight cone with sufficient rigidity and loss. The edge also features an up-rolled shape for a long stroke, and is made from a high-loss foam rubber edge.

■Mechanical 2-Way Center Cap
The center cap is made from the same material as the cone paper, enhancing the consistency of the tonal quality. It is also directly connected to the voice coil bobbin, resulting in a mechanical 2-way structure that expands the high-frequency playback range.
