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
Diaphram mass, in grams
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."

Re: Mms to Mmd calculations
Double-click on the Hornresp Mmd input box when in edit mode, and then simply follow the instructions :-).
