The pole pieces are spaced apart with the pole tips being opposed across an air gap. Each pole tip is flared toward the air gap. The magnetic assembly may further include a first permanent magnet in contact with the first pole piece and a second permanent magnet in contact with the second pole piece. The magnetic assembly may be a part of an electromagnet transducer further having a voice coil positioned at least partially within the air gap.
