The acoustic properties of titanium alloy have been increasingly recognized by the music industry. The conduction speed of the sound wave is 6070 m/s in titanium alloy. While in the synthetic materials, the sound wave conduction speed is only 920 m/s. In titanium alloy, the sound speed is at least six times faster than synthetic materials. High-speed sound transmission makes the cello body vibration, significantly improved sound quality, better sound clarity, volume increased, better sensitive and rich sound. Cello built-in tailpiece type fine tuner is reasonably designed, easy to use. They were almost all made from synthetic materials (or synthetic resin with carbon fibers) and they have been ignored the importance of the speed of acoustic conduction. Stradpet team uses high-tech production process to produce cello titanium alloy fine tuners. They are much better than synthetic materials.
