The Difference between Helix and Amphitheatre Cups
We use patented helix system in the most expensive versions of wooden cups. The process of making such cups is very labour intensive and time-consuming. But the result attained when you use this configuration is worth the effort. An amphitheatre is a set of flat surfaces located at various depths and creating a pattern of favourable reflections. A helix does not have any flat surfaces and is asymmetric at every point; therefore, it disperses sound waves inside the cup chaotically, giving an incomparably richer pattern of internal re-reflections than an amphitheatre.
A helix provides better resonance suppression system that means that the dispersion of sound waves is much higher.
