Features: 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 fireproof board, thick copper layer can withstand large current. Use of polypropylene film divider special capacitance and high temperature-resistance wire inductance coil. The upgraded model has better resistances performances, better sound quality, and is not easily crushed during transportation. Specifications: Max Power: 80W Frequency Response: 48 Hz - 20K Hz Impedance: 4-8 Size:Approx.74x60mm/2.91''x2.36'' Note: Please allow 1mm errors due to manual measurement. Due to the difference between different monitors, the picture may not reflect the actual color of the item. Package includes: 1x Frequency Divider
