the PC31 with the classic 40mm silver ring unit, code-named X3 acoustic chamber. Fengyun 40mm silver ring unit with strong NdFeB magnets as the core CCAW than 8 times normal magnetic core, the performance is more sensitive, more broad frequency response, low frequency dynamics and details of the performance is more prominent. This time the unit with the latest design of the X3 Charm cavity transmission grid system is expected in the superior low frequency performance.
