Wavecor WF120BD07 11 cm bass midrange 4ohm

The 4¾” transducers WF120BD03 (4 ohm) and WF120BD04 (8 ohm) were designed as high performance bass and midrange units for very compact monitors and high-end hi-fi speakers.
The only difference between WF120BD03 and WF120BD07 is the shape of the mounting flange of the frames. WF120BD04 and WF120BD08 differ in the same way.

• 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
• Black coated semi-air-dried paper cone
• Rigid die cast alu chassis with extensive venting for lower air flow speed reducing audible distortion
• Large motor for better control and power handling
• Vented voice coil former 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
• 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
