Description:
1. Magnetic circuit system: rare-earth aluminum-iron-boron magnetic structure + short-circuit ring copper sleeve, solves the thoroughness of medium and high frequency from the starting point.
2. The cones are mainly bass and mid-high, and cotton fibers are selected through various screenings.Treble cup material selected bamboo + bark fiber, high-frequency thorough and not harsh.
3. high temperature resistant copper clad aluminum wire with Kapton skeleton + high heat dissipation coating, the speaker heart has excellent quality.
4. Pure copper plated gold terminals ensure zero resistance contact and do not let go of a music signal, achieving high fidelity.
