Wavecor FR070WA04, 8 Ohm Fullrange
The 2¾” transducers FR070WA03 (4 ohm) and FR070WA04 (8 ohm) were designed especially for high quality multimedia and lifestyle speakers, where sound reproduction without compromises is required.
FEATURES
- True full-range design with on-axis output to beyond 25kHz
- 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 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
