Wavecor WF223BD02 8.5" die cast paper/glass fiber cone 8 Ohm


The 8¾” transducers WF223BD01 (4 ohm) and WF223BD02 (8 ohm) were designed as high performance bass/midrange units for  monitors and high-end hi-fi speakers. They offer outstanding deep bass performance and dynamic and detailed midrange.
Ideal for 3-way constructions they additionally offer designers the rare opportunity of working with 8” 2-way solutions if paired with a suitable tweeter like for instance some of the Wavecor 30 mm units.



  • Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
  • 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
  • Cone made of a new paper/glass fiber mix with improved consistency and stability
  • Rigid die cast alu chassis with extensive venting for lower air flow speed reducing audible distortion
  • Vented voice coil former for reduced distortion and compression
  • Vented center pole with dual flares for reduced noise level and compressions at large cone excursions
  • Heavy-duty black fiber glass voice coil former to reduce mechanical losses resulting in better dynamic performance and low-level details
  • Large motor with 1½” 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 plated 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
