1. Circuit: The treble, mids, and bass all feature a standard 12 dB/second circuit. 2. frequency band current limiting over current protection bubble: When the current is low, the bubble acts as a wire; if the current is too , it functions as a load, dissipating the electricity to prevent the tweeter from burning due to excessive current. This is a movable type of protection. 3. The inductor is wound with oxygen copper wire. The bass coil uses a 1.2 mm wire diameter, the mid coil uses 1.1 mm, the mid low coil uses 1.0 mm, and the tweeter coil uses 1.0 mm. The copper wire delivers full power, making the bass more powerful. 4. The capacitor employs a non inductive MKP capacitor with a voltage strength of 400V, preventing peak voltage surges from damaging the speaker. The design is well balanced, the appearance is sleek, and the sound quality is exceptional. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
