The topological driver refers to the nano-particle-based plating of the diaphragm, applied to reproduce geometric patterns. By varying this pattern the spectrum can be manipulated pto offer an ever better sound.
The idea behind this technology is inspired by the thesis of Dr. Fang Bian's Ph.D., arguing that "different nano-materials have different structures and each of these materials has its own properties." Thus, by carefully controlling the structure of the surface of the diaphragm, you obtain acoustic results that were previously unattainable. Moreover, the distortion is greatly reduced and the dynamics improved.
