    The  3½" transducers WF090WA01 (4 ohm) and WF090WA02 (8 ohm) were designed especially for high quality multimedia and lifestyle speakers, where small size is required while still obtaining sound reproduction without compromises.

    • Vented voice coil former for reduced distortion and compression
    • Vented chassis for lower air flow speed reducing audible distortion
    • Voice coil wound with Copper Clad Aluminium Wire for higher efficiency and better dynamics
    • 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
    • Low-loss suspension (high Qm) for better reproduction of details and dynamics
    • Black magnet parts for better heat transfer to increase power handling
    • 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
    • Delivered with foam gasket attached for hassle-free mounting and secure cabinet sealing
