BQEYZ Topaz Gray

TOPAZ employs a hybrid driver with dynamic + piezo (piezoelectric) ceramic arranged coaxially.
The dynamic driver with a large diameter of 13 mm uses LCP (liquid crystal polymer) material with high rigidity, elasticity and excellent heat resistance for the vibration plate, and demonstrates high density and smooth sound performance. The 9-layer piezo-ceramic driver patented in China reproduces the details of the sound source and works with the dynamic driver to improve performance.
By adding another cavity behind the conventional dynamic driver and creating a dual-cavity structure, it achieves a more airy and thick vocal. By effectively controlling the air pressure and facilitating the drive of the diaphragm, any device can demonstrate better performance.
