    The 3½” transducers FR090WA01 (4 ohm) and FR090WA02 (8 ohm) were designed especially for high quality multimedia and lifestyle speakers, where sound reproduction without compromises is required while still keeping size small.

    • True full-range design with on-axis output to beyond 20kHz
    • 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
    • Black anodized alu cone for better heat transfer
    • Vented steel chassis for lower air flow speed reducing audible distortion
    • Vented voice coil former for reduced distortion and compression
    • Heavy-duty black fiber glass voice coil bobbin to reduce mechanical losses resulting in better dynamic performance and low-level details
    • Large motor with 22 mm voice coil diameter for better control and power handling
    • Low-loss suspension (high Qm) for better reproduction of details and dynamics
    • Black motor parts for better heat transfer to the surrounding air
    • Conex spider for better durability under extreme conditions
    • Gold plated terminals to ensure long-term trouble free connection
    • Delivered with EVA gasket attached for hassle-free mounting and secure cabinet sealing
