More info

Nominal impedance is 4 ohm for WF146WA01 and 8 ohm for WF146WA02. Otherwise the two models are identical.
WF146WA01/02 are mid/woofers designed for demanding bass and midrange applications. They work equally well for high-end hi-fi, high quality home theater systems, and top multimedia setups.
Powering is by a large 90 mm magnet structure that ensures good efficiency and optimal T/S parameters.

WF146WA01/02 are very good choices for compact 2-way speaker systems or even as midrange in multi-way systems.

  • Alu field-stabilizing ring inside magnet assembly for reduced high-level distortion
  • Vented voice coil former for reduced distortion and compression
  • New 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 90 mm magnet for better control, power handling, and efficiency
  • Black magnet parts for better heat transfer to increase power handling
  • New progressive 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
