A combination of rigid mica and light pulp enable the cone to reproduce clear, energetic Loud & Aggressive sound.






A surface containing mica properly maintains the cone’s superior rigidity and internal loss. The back makes excellent use of light, water-resistant material. Various materials were carefully combined to develop a diaphragm of extra lightness and rigidity to reproduce sound clearly with outstanding responsiveness, sensitivity and a suitable degree of internal loss.
