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.
FEATURES
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
