8NMB750 18 Sound

8" Mid Bass Neodymium speaker 700w

  • 18 Sound’s 8NMB750 mid-bass neodymium transducer is a state-of-the-art 8-inch mid bass driver that combines excellent linearity with high power handling capabilities (700 W) and reduced power compression.
  • The external neodymium magnet assembly assures high flux concentration and excellent heat exchange.
  • The 75mm (3 in) inside outside aluminum voice coil employs Interleaved Sandwich Voice coil (ISV) technology.
  • A sophisticated distortion reduction system has been implemented using a demodulating ring for flux modulation cancellation related to voice coil excursion, together with a copper ring for the reduction of intermodulation distortion. Both systems are linearizing the inductance in relation to the excursion as well as the current variation.
  • The cone is treated against extremely aggressive environment conditions.
  • The compact size makes the 8NMB750 an ideal choice for high performance line arrays and compact two-way systems.
