NEW 1” High Frequency Compression Driver, 1.75” voice coil, 40 W, 110 dB

 

ND45-pic

KEY FEATURES:

  • 1” Exit Throat
  • 1.75” Diaphragm
  • Neodymium magnet assembly
  • 80 W continuous program power
  • Frequency range: 1kHz - 20kHz
  • New phase plug design
  • Copper inductance ring for extended response
  • Vented suspension

 

 

The ND45 is new improved version of ND2545.

It is 1” high frequency neodymium compression driver, that incorporates new phase plug, new dome with vented suspension and copper inductance ring, which improve sound characteristic and ensure very low distortion at high sound levels.

The smooth impedance response in crossover region ensures perfect work with passive crossovers

The reduced weight and size make it preferable for high quality compact 2 way and line array boxes. The voice coil assembly is easily field replaceable without soldering.
