To provide physical symmetry, the magnet is made so that it has the same flux above and below the voice coil, when no current is applied. This is a matter of making the fixed magnet physically symmetrical, but does not address the issue of flux modulation from electromagnetism. The use of a flux stabilization ring generates counteractive flux to the modulating force of the field coil. Magnums incorporate such a device.
