FR090WA02

3¾ alu-cone fullrange, 8 ohm

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

Features:
  • 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
