The view from above shows the two "alternative" suspension methods: Rubber foam feet for the bars, stiff wire for the tubes.
Here is a closup. The loop of the wire stabilizes the bar and prevents swinging. At the bottom of the tube, the wax can be seen.
The resonator tubes form a nice arc.
Here it is!
