Wavecor WF223BD02 8-3/4" Balanced Drive Paper/Glass Fiber Cone Mid-Woofer 8 Ohm

Wavecor
Part #298-1214  
Model: WF223BD02
The Wavecor WF223BD02 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 WF223BD02 is a very good choices for either 2 or 3-way speaker systems.
Key Features
  • 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
  • rogressive suspension with specially designed conex spider for long durability under extreme operating conditions

Overview

Wavecor WF223BD02 8-3/4" Balanced Drive Paper/Glass Fiber Cone Mid-Woofer 8 Ohm

The Wavecor WF223BD02 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 WF223BD02 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.
