Wavecor FR084WA01 3-1/4″ Aluminium Cone Full-Range 4 Ohm
Overview:
The 3-1/4″ FR084WA01 from Wavecor is a 4 ohm full range driver that was designed specifically for high quality multimedia speakers. This driver offers sound reproduction without compromises while still retaining a size small.
Highlights:
- True full-range design with on-axis output to beyond 20 kHz.
- 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 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
- Delivered with foam gasket attached for hassle-free mounting and secure cabinet sealing.
Product Description:
Wavecor’s FR084WA01 is a compact 3-1/4″ full range driver that offers many excellent features that make it comparable to drivers costing much more. The copper cap utilized is designed to reduce the inductance of the driver.
The vented polymer chassis and voice coil former increase the airflow of the driver resulting in reduced distortion. In addition, the anodized-black aluminum cone also provides improved heat transfer. All of these features paired with its excellent lack of distortion and frequency response make this driver excellent for any application that requires high-fidelity playback in a compact package.
