. Feature: Using overcurrent protection device. The high power non-polar capacitor, the low frequency part is converted by inductance to achieve a clear and full effect. PCB floor with fire board, thick copper layer can withstand large current. Use of polypropylene film divider special capacitance and high temperature resistance wire inductance coil. The crossover is a circuit device in the speaker, which separates the sound signals of different frequency bands (treble, midrange, and bass), amplifies them separately, and then sends them to the speakers of the corresponding frequency bands for playback. Frequency Divider only, other accessories demo in the picture is not included Specifications: Item Type: Speaker Frequency Divider Material: ABS Size of Circuit Board: 45x56mm / 1.77x2.20inch Color: As picture shown Quantity: 1 Pc Maximum Power: 80W Impedance: 4-8 Application: Speakers under 5 inch Note: Please allow 0-1mm error due to manual measurement, pls make sure you do not mind before you bid.
