Development of this series began in 2016 and launched in 2017 after meticulous engineering efforts to achieve top quality. Significant investment was made in custom molds, as standard materials couldn’t meet our standards. Utilizing a unique polymer material with light weight, high stiffness, and ideal damping, the design offers exceptional vibration control and sensitivity. With precise mechanical damping and optimized q-value, it delivers high sound density, dynamic control, and crystal-clear audio. The result is smooth, natural sound reproduction, making this rare speaker unit a must-have for audiophiles.
