The Fountek FM135D-II is a 5¼" / 135mm midrange driver featuring an aluminium cone, a rigid diecast basket and a high temperature copper clad aluminium voice coil wound on a 35mm kapton former.

Operates as a pure piston between 120 - 400Hz then the response gently tapers upwards to 5Khz, our recommended upper limit for this unit. As to be expected with a small metal coned drive unit, the FM135D-II has an excellent transient response. The first major cone breakup occurs at around 7Khz, this is easily avoided or notched in the crossover.

FEATURES

  • Aluminium cone - excellent transients
  • Non resonant diecast chassis
  • 35 mm CCAW voicecoil
  • High compliance rubber suspension
  • Kapton voice coil former
  • Smooth frequency response
  • Neodymium magnet system

 

SPECS:

Resonant frequency (fs) 73 Hz Nominal impedance (Zn) 8 Ω
Mechanical  Q factor (Qms) 1.84 DC resistance (Re) 6 Ω
Electrical Q factor (Qes) 0.69 RMS power handling 30 W
Total Q factor (Qts) 0.28 Sensitivity (2.83V/1m) 89 dB
Equivalent volume (Vas) 6.47 L Chassis diameter 150 mm
