Hi, you need to measure the area of the diaphragm Sd, this should help Thiele/Small parameters - Wikipedia
and quoted from the above : Sd
Measured in square metres (m²). The effective projected area of the cone or diaphragm. It is difficult to measure and depends largely on the shape and properties of the surround. Generally accepted as the cone body diameter plus one third to one half the width of the annulus (surround). Drivers with wide roll surrounds can have significantly less Sd than conventional types with the same frame diameter.
