1. Second-order bass, second-order treble to achieve phase compensation 2. Good combination of high-power resistance 3. Diameter inductance meets high current 4. Applicable to: 4-8 ohm speakers/power 500W 5. Bass inductance + polymer magnet to improve bass drop, reasonable circuit + high-quality components + high cost-effectiveness = accurate sound It adopts wire diameter and inductance, high-quality metal film capacitors, high-power resistors, and aluminum heat dissipation, adjustable switches for treble and low frequencies, self-repairing protection device, high-quality, shocking sound effect of the scene without losing treble details performance. To allow the current to pass quickly, increase the effect of the frequency divider; work hard on design and workmanship; the solderless terminal block is of high quality and generous, and it is very convenient to use.
