AB  - When a voice coil is surrounded by a conductive medium, such as a short-ring or pole piece in close proximity, the impedance becomes lossy. The conductive medium impedance itself derived from the well-known skin depth – impedance relationship that describes the impedance has the frequency-dependent of v?. This frequency dependence holds when the effective short-ring thickness is sufficiently thicker than the skin depth. In practice, many short-rings do not have sufficient thickness for mid to low frequency. Therefore the lossy voice coil impedance characteristics deviate from the idealized lossy impedance model. The short-ring thickness is implemented in t
