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

Quick Overview:

 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.

Product Highlights:

  • Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
  • 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
  • Cone made of a new paper/glass fiber mix with improved consistency and stability
  • Rigid die cast alu chassis with extensive venting for lower air flow speed reducing audible distortion
  • Vented voice coil former for reduced distortion and compression
  • Vented center pole with dual flares for reduced noise level and compressions at large cone excursions
  • Heavy-duty black fiber glass voice coil former to reduce mechanical losses resulting in better dynamic performance and low-level details
  • Large motor with 39 mm voice coil diameter for better control and power handling
  • Built-in alu field-stabilizing ring for reduced distortion at high levels
  • Low-loss suspension (high Qm) for better reproduction of details and dynamics
  • Black plated 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

Product Description:

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.
