This series started to be developed as early as 2016, but it was not available until 2017 because when our engineers strived to achieve the best quality. Our company also invested a lot of money to Customized the mold because the common materials on the market could not meet the requirements. So from the design to the materials used, it took all the engineers’ efforts. Good parameters are obtained from the design, there is no sewing process. The process of research and development will not be revealed, I believe that a slight understanding of the picture can feel the overall quality of the product, is indeed a rare speaker unit, do not miss a good partner!

High sound density, great dynamic control, clear dynamic and static

Fine calculation of mechanical vibration damping and q-value of electrical properties


Unique special polymer material

This material combines light weight, high stiffness, and ideal damping characteristics to optimize its vibration characteristics and reduce the weight of the sound-emitting part

Greatly improved sensitivity and smooth, natural reproduction of the original sound
