Resonanzrohr-Konzepte

	In the classic panpipe arrangement, the individual resonance tubes (made of aluminum or plastic) are fixed in two metal rails.
	Using the tube-in-tube concept, the resonance tubes are individually inserted into a receiving sheetmetall. The tubes are supported by rubber pads on the receiving sheetmetall. O-rings on the tubes prevent them from swinging against each other. The tubes can therefore be removed individually and plugged one into the other according to their diameter for a volume-reduced transport. The sheetmetall part is foldable. However, the resonance tubes can also remain in the sheetmetall for transport and then be folded together to a comfortable size Alternatively, the resonance tubes can also be transported as a panpipe in the unfolded state. Thus the tube-in-tube concept offers all imaginable transport options in one. It is applicable to aluminum tubes, PVC-tubes and PETG tubes.
