1. Adopt high-power output bass driver with double-layer copper voice coil wound inside and outside

2. The inner and outer voice coils have double heat dissipation surface area and stronger voice coil strength.

3. Good heat dissipation is conducive to the reduction of compression power when the speaker works at critical high power, and ensures the long-term stable operation and high-efficiency output of the speaker.

4. The carefully optimized tuning makes the speaker have a good transient. The improved phase inversion system not only reduces the wind noise and air flow in the pipe, but also strengthens the structure of the box, reduces the adverse vibration of the box, and makes the sound more pure and solid.
