7", die cast alu, 120 mm ferrite, cu cap, 1½" VC, 4 ohm

Wavecor WF182BD03-01 (ea.) midbass driver's product information

The 7” transducers WF182BD03 (4 ohm) and WF182BD04 (8 ohm) were designed as high performance bass and midrange units for monitors and high-end hi-fi speakers. They offer outstanding deep bass performance and dynamic and detailed midrange..

FEATURES

  • Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced 2nd 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
  • Black coated semi-air-dried paper cone
  • 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 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 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
