Overview

Wavecor WF118WA02 4-1/2" Paper Cone Mid-Woofer 8 Ohm

The Wavecor WF118WA02 is a 4-1/2" paper cone midwoofer designed for demanding bass and midrange applications. It works equally well for high-end hi-fi, high quality home theater systems, and multimedia projects. The WF118WA02 is an ideal choice for a compact 2-way speaker design as a midwoofer.

Powered by a large 85mm magnet structure, the WF118WA02 is ensured excellent efficiency and optimal T/S parameters. The large 32mm 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.
