NEW 1” High Frequency Compression Driver, 1.75” voice coil, 40 W, 108.5 dB

 

d44-pic

KEY FEATURES:

  • 1" Exit Throat
  • 1.75" Diaphragm
  • 80 W continuous program power
  • Frequency range: 1000Hz - 20kHz
  • New phase plug design
  • Copper inductance ring for extended response
  • Vented suspension

 

 

The D44 is new improved version of D2544.

It is 1” high frequency compression ferrite 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

It is suitable for use in high quality 2 way and 3 way boxes. The voice coil assembly is easily field replaceable without soldering.
