Wavecor WF182BD03 7" Balanced Drive Paper Cone Mid-Woofer 4 Ohm

Quick Overview:

The Wavecor WF168BD03 is a 7" paper cone midwoofer that utilizes balanced drive technology and is designed for demanding bass and midrange applications. The WF168BD03 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 2nd 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
Black coated semi-air-dried paper cone
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 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 1.5” 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 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 WF168BD03 is a 7" paper 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 WF168BD03 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 cone ensures wide bandwidth and low distortion. Distortion is further reduced by efficient venting of the chassis and voice coil former.
