1. The cone is made of cotton and linen fiber + bark fiber, and the hanging edge is made of rubber and foam composite. Due to the high sensitivity, 25W-40W can be easily pushed.
2. The polymer sound cap with the same damping coefficient as the sound basin is used. The polymer sound cap has good damping coefficient and strong elasticity. The cavity sound brought by harmonics is solved from the design.
3. The diversion double magnetic circuit system is adopted to ensure that the bass is clean, strong and fast in high-power long-stroke operation.
4. It adopts long-stroke, high-power design and low-frequency flexibility. It is suitable for making 2.1 subwoofer speaker and two-way speaker . It is also a good choice for upgrading computer speaker subwoofer.
