The history of these gongs can be traced in part from the epigraphy and iconography of Funan-Chenla and Angkor periods, for many can be seen carved on ancient Khmer temple.
The instrument is held up with 16 supports, made of neang nuen, krennoonf, or beng wood.
The gong circle is held together with six crossbars, designed to keep the distance between the inner and outer frames fixed.
In addition to this, the gongs are tuned by sticking promor (a lead and wax combination) to the underside of the nipple.
The heads are made from the earlier mentioned promor, which is then wrapped in four or five layers of cloth and stitched with nylon thread.
