ABSTRACT:
An apparatus and method for centering a voice coil in a loudspeaker having a vented pole piece. The voice coil centering is accomplished by means of a concentrically located voice coil suspension and an attached cylindrical mounting ring that can be set into a recess, or otherwise positively located on the pole piece. The pole piece is formed in such a way so as to precisely receive a suspension mounting ring and center the voice coil in the magnetic field gap with no further adjustments. This invention permits the use of a pole piece mounted voice coil suspension on a ventilated pole piece.
