Wavecor FR055WA04 2" Neodymium, alu-cone fullrange 8 Ohm


The 2” fullrange transducers FR055WA03 (4 ohm) and FR055WA04 (8 ohm) were designed especially for high quality multimedia and lifestyle speakers, and for personal audio products, where sound reproduction without compromises is required.
Will additionally work well as a midrange/treble transducer in small speaker products in combination with for instance a small subwoofer unit.


  • True full-range design with on-axis output beyond 20kHz
  • Upgraded design with higher efficiency and improved high frequency output
  • Dual neodymium magnet structure for high efficiency and almost ideal magnetical shielding
  • 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
  • Black anodized alu cone for better heat transfer
  • Vented polymer chassis for lower air flow speed reducing audible distortion
  • Vented voice coil former for reduced distortion and compression
  • Heavy-duty black fiber glass voice coil bobbin to reduce mechanical losses resulting in better dynamic performance and low-level details
  • Large motor with 22 mm voice coil diameter for better control and power handling
  • 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) = 10 W
  • frequency range = 100-40000 Hz
  • resonance frequency fs = 131 Hz
  • impedance R = 8 Ohm
  • sound pressure level SPL = 83 dB (2,83V; 1m)
  • DC resistance Re = 6,2 Ohm
  • force factor BL = 3,3 N/A
  • voice coil inductance L = 0,1 mH
  • effective piston radiating area Sd = 15,6 cm2
  • effective mechanical mass incl. air load mms = 1,54 g
  • equivalent volume of compliance Vas = 0,33 l
  • total Q factor Qts = 0,64 (Qms=7,9, Qes=0,7)
  • voice coil diameter = 22 mm
  • maximum peak linear excursion vibration xlin = +/- 1,35 mm
  • mounting diameter d = 51 mm
  • overall diameter d = 55x55 mm
  • mounting depth (not countersunk) t = 32,5 mm
