Hi Chinese,
Look on this page for idea to make sound smooth and very clear. Can be done with pen and acrylic paint. You give me measurements and I provide pattern.

Hi Chinese,
Very small thickness of paint. Flat, clear, acrylic paint, very thin, applied with calligraphy pen, so control amount of paint Make pen strokes only where black blocks are shown on conic section. Add very little mass, not mistreat high frequencies, remove standing waves and reflected waves at end of cone. Also at beginning, even less paint, much smaller pen tip, much smaller stroke. Only to control area at cone surface and air, boundary layer, not control piston with mass, only bending surface where all energy is emitted.
Try or not, your decision, works well on other side of the planet from you on all speaker types available. Maybe learn and try on regular cone speaker, cheap, maybe 200 cm diameter.

Chinese,
Sorry meant 200 mm
Dimensions to put into my program to provide marking template for correct position of pen strokes. Need final diameter, beginning diameter and length of cone wall, not height of cone, actual length of surface.
This is not damping rubber. This is a thin paint, dries hard, 80% moisture which evaporates. Stiffens paper fibers on surface and just under surface. Not mass damping. surface control of ends of cone area and also the entire cone surface, just from ends of cone, where ringing begins and reflects.
