The use of multiple high-temperature inductors significantly improves the sound quality and the inductors are staggered at 90 to avoid mutual interference. Multiple audio-specific capacitors certified by multiple countries make the muddy sound quality clear, delicate, and layered. The effect of adjusting the treble can be applied to more speakers. Different sound quality effects can be achieved according to different occasions. The use of self-recovery + protection bulb dual protection further protects the speaker and prevents the speaker from burning out due to excessive current. The eight-position solder-free terminal block can be easily installed by tightening the screws without welding experience.
