Mms to Mmd calculations

Mmd is required for hornresp.
Normally we get Mms specs.
How to get Mmd from Mms.

MOVING MASS, AIR LOAD: MMS (GRAMS) . . . . 166.71
MOVING MASS, DIAPHRAGM: MMD (GRAMS). . . . 163.01

DRIVER RADIATING AREA: SD (IN2) . . . . . . 53.40
SD (CM2). . . . . . . 346.00

Mmd
Diaphram mass, in grams
Mms
The driver's effective mechanical mass (including air load), in kg. "This parameter is the combination of the weight of the cone assembly plus the ‘driver radiation mass load’. The weight of the cone assembly is easy: it’s just the sum of the weight of the cone assembly components. The driver radiation mass load is the confusing part. In simple terminology, it is the weight of the air (the amount calculated in Vd) that the cone will have to push."
