SonoraSonora's tubular bells produce a soothing melodious tone with outstanding resonance. The 21 tubular bells are made from hand tuned, heavy duty anodized aluminum and are each mounted individually over black anodized aluminum resonators which are equally precisely tuned. Each resonator is individually capped with a polyurethane rain baffle. Finally, stainless steel security fixings deter vandalism and prevent the theft or removal of the instrument.
