I thought of filling with sand braided multifilament nylon cable sleeving (http://cableorganizer.com/nylon-multifilament/) which comes in 2 inch diameter and does not expand enough to allow coarse sand to come out. It can be wrapped around as densely or sparsely as required. The problem is that it offers little structural support, though the tension of the fabric may convert some of the weight into compression. So the underlying structure has to be very rigid, it seems to me.

I thought about it already and do not think the tubing will work. I think to key in made sand dimpling to work is force considerable amount of sand pressure to the frame of the horn. In case belts used I thought (if I go this route) to use tension adjustable joins on the belts. This way the sand bags might be positioned, fixed with the belts and then the belts hard pressed to the horn, something like this.
