Wavecor MR120BD02 4¾" die cast, Kevlar/Carbon cone midrange 8 Ohm


The 4.75” transducers MR120BD02 (round, 8 ohm), is designed as high performance midrange units for high quality multi-way speakers.


  • New cone of interwoven Kevlar/Carbon fibers, a new reference for the combination of low mass, rigidness, and damping - highly beneficial properties for midrange reproduction
  • Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
  • Vented, inverted center dome for reduced compression
  • Copper cap on center pole to reduce voice coil inductance and to minimize variations in voice coil inductance as a function of voice coil position
  • Rigid die cast alu chassis with extensive venting for lower air flow speed reducing audible distortion
  • Heavy-duty black fiber glass voice coil former to reduce mechanical losses resulting in better dynamic performance and low-level details
  • Large motor with 1” voice coil diameter for better control and power handling
  • Built-in alu field-stabilizing ring for reduced distortion at high levels
  • Low-loss suspension (high Qm) for better reproduction of details and dynamics
  • Black motor parts for better heat transfer to the surrounding air
  • Conex spider for better durability under extreme conditions
  • Gold plated terminals to ensure long-term trouble free connection



  • power handling (continuous/programme) = 50 W
  • frequency range = 200-4000 Hz
  • resonance frequency fs = 73 Hz
  • impedance R = 8 Ohm
  • sound pressure level SPL = 86 dB (2,83V; 1m)
  • DC resistance Re = 6,4 Ohm
  • force factor BL = 5,2 N/A
  • voice coil inductance L =  mH
  • effective piston radiating area Sd = 50 cm2
  • effective mechanical mass incl. air load mms = 5,5 g
  • equivalent volume of compliance Vas = 3,1 l
  • total Q factor Qts = 0,56 (Qms=8,3, Qes=0,60)
  • voice coil diameter = 26 mm
  • maximum peak linear excursion vibration xlin = +/- 1,5 mm
  • mounting diameter d = 100 mm
  • overall diameter d = 120 mm
  • mounting depth (not countersunk) t = 64 mm
