Special Features

• Wooden base included in delivery
• Comments according to product sheet:
  • The pure magnesium diaphragm has higher internal damping, improving super high frequency reproduction. It avoids the usually unpleasant sound characteristics of metal diaphragms.
  • Powerful drive by a 2-way magnet with 40mm diameter.
  • High-strength, silver-coated copper wire for the voice coil with a thickness of 1.4mm.
  • A newly developed horn design with a new cut-off frequency made from a solid block of brass, ultra-precisely milled.
  • Copper connection terminals and a copper-coated pole core plate ensure the lowest possible signal losses.
  • A tungsten diaphragm ring and sealing washer optimise resonance behaviour.
