Wavecor WF118WA07 4-1/2" Balanced Drive Paper Cone Mid-Woofer with Truncated Frame 4 Ohm
The Wavecor WF118WA07 is a 4-1/2" truncated frame paper cone midwoofer that is designed for demanding bass and midrange applications. This driver utilizes balanced drive technology for reduced distortion. It works equally well for high-end hi-fi, high quality home theater systems, and multimedia projects. The WF118WA07 is an ideal choice for a compact 2-way speaker design as a midwoofer.
Powered by a large 80 mm magnet structure, the WF118WA07 is ensured excellent efficiency and optimal T/S parameters. The large 1-1/4" voice coil allows excellent high-power handling, both thermally and mechanically. The optimized paper cone ensures large bandwidth and low distortion. Distortion is further reduced by the efficient venting and an aluminum shorting ring stabilizing the magnetic field in the air gap.
