More info

The 1½” transducers FR040WA01 (4 ohm) and FR040WA02 (8 ohm) were designed especially for high quality multimedia and lifestyle speakers, and for personal audio products, where sound reproduction without compromises is required.
Will work well as a midrange/treble transducer in small speaker products in combinbation with for instance a small subwoofer unit.

  • True full-range design with on-axis output to beyond 20kHz
  • Dual neodymium magnet structure for high efficiency and almost ideal magnetically shielding
  • 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
  • Optimized off-axis response
  • Vented polymer 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 16 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 connectionFR040WA02-SPL-response
  • FR040WA02-IMP-response
