The Wavecor WF168BD03 is a 7" paper cone midwoofer that utilizes balanced drive technology and is designed for demanding bass and midrange applications. The WF168BD03 is a very good choices for either 2 or 3-way speaker systems.

Key Features

  • Vented voice coil former for reduced distortion and compression
  • Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced 2nd order harmonic distortion
  • Built-in aluminum field-stabilizing ring for reduced high-level distortion
  • Large motor structure for better control and power handling
  • 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
  • New vented chassis for lower air flow speed reducing audible distortion
  • Progressive suspension with specially designed conex spider for long durability under extreme operating conditions
