  • "Schott AS87 Glass"-"Viscoelastomic Damping Layer"-"Aluminum alloy foil" composite flat diaphragm in total thickness of 0.3mm and mass of 3.4g
  • 17mm thickness with 8mm X-max. Highest in-industry Excursion-to-Thickness Index (E2T)
  • Very high force motor: 2.84 kgF (continuous), 6.44kgF (transient)
  • High power handling: 35W (continuous), 180W (transient)
  • High Mms for low Fo both in free-air and in-box, plus high BL (BL=4.34) for maintaining the demanded sensitivity
  • Large eff.-radiating-area (SD=4865 mm²) to overall area (64%)
