6 1/2 die cast car woofer, 4 ohm

WF166TU02 is a mid/woofer designed for demanding bass and midrange applications. It works equally well for most applications but is designed especially for automotive high-end sound. The optimized paper cone ensures wide bandwidth and low distortion. Distortion is further reduced by efficient venting and a separate alu field-stabilizing ring. WF166TU02 is a good choice for 2-way car speaker systems.

  • Very rigid die cast alu chassis
  • Built-in alu field stabilizing ring for reduced high-level distortion
  • Vented voice coil former for reduced distortion and compression
  • Vented chassis for lower air flow speed reducing audible distortion
  • Heavy-duty black fiber glass voice coil bobbin to increase power handling and reduce mechanical losses resulting in better dynamic performance and low-level details
  • Large motor system with 1¼ voice coil diameter and large 90 mm magnet for better control and efficiency
  • Linear suspension with specially designed CONEX damper (spider) for long durability under extreme operating conditions
  • Gold plated terminals to prevent oxidation for long-term reliable connection - important in a car environment
