The Eighteen Sound / 18 Sound 8M400F 8" Woofer 250W @ 8Ω

The 8M400F is a high power, high output, 200 mm (8 in) midrange for high level professional use. The excellent sound quality has been achieved as a result of extensive research on mid frequencies intelligibility.The 8M400F has been designed for use as a midrange in both horn and direct radiation, closer or reflex enclosures, as small as 3 lt. The curvilinear cone, made with a high damping wood pulp, has been designed to achieve the best possible linearity within its frequency range.The powerful magnet assembly assures high flux concentration. The force factor and power handling are at an optimum level. The direct contact between the finned basket and the magnetic structure significantly improves thermal connection and heat dissipation, further increasing power handling and lowering power compression.The copper shorting ring on the pole piece reduces inductance and improves transient response and phase control in the mid frequencies.

  • 51 mm (2 in) Interleaved Sandwich Voice coil (ISV)
  • 250 Watt AES power handling
  • Improved heat dissipation via unique basket design
  • Copper ring to linearize impedance curve
  • Suitable for high quality midrange applications
