Wavecor WF223BD01 8-3/4″ Balanced Drive Paper/Glass Fiber Cone Mid-Woofer 4 Ohm
Quick Overview:
The Wavecor WF223BD01 is an 8-3/4″ paper/glass fiber cone midwoofer that utilizes balanced drive technology and is designed for demanding bass and midrange applications. The WF223BD01 is a very good choices for either 2 or 3-way speaker systems.
Product Highlights:
- Vented voice coil former for reduced distortion and compression
- Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced 2nd order harmonic distortion
- Built-in aluminum field-stabilizing ring for reduced high-level distortion
- Large motor structure for better control and power handling
- 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
- New vented chassis for lower air flow speed reducing audible distortion
- Progressive suspension with specially designed conex spider for long durability under extreme operating conditions
Product Description:
The Wavecor WF223BD01 is an 8-3/4″ paper/glass fiber cone midwoofer that is designed for demanding bass and midrange applications. This driver is powered by a large magnet structure that ensures good efficiency. The WF223BD01 is a very good choices for 2-way speaker systems or even as midrange in 3-way systems.
The large motor system with 1-1/2″ voice coil diameter and large magnet for better control, power handling, and efficiency. The optimized paper/glass fiber cone ensures wide bandwidth and low distortion. Distortion is further reduced by efficient venting of the chassis and voice coil former.
