Improve the separation and mutual interference of the whole machine, making it work more stably. Ensure the dynamics and speed of its large-scale music. The transformer is divided into two 12W+12W sections, made of oxygen free copper wire and Japanese Z11 silicon steel sheet. It has a medium frequency thickness, high density, warm sound, and better performance than the ring type.
