Wavecor WF182BD09 7″ Balanced Drive Paper/Glass Fiber Cone Mid-Woofer 4 Ohm

Quick Overview:

The Wavecor WF182BD09 is a 7″ paper/glass fiber cone midwoofer that utilizes balanced drive technology and is designed for demanding bass and midrange applications. The WF182BD09 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 WF182BD09 is a 7″ 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 WF182BD09 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.
