The 66mm high temperature resistant inductance is used to allow low frequency signals to pass through quickly, reducing heat generation and displaying frequency response.Each of the two treble channels has own PTC treble protector.On the whole, the partition concept is used to design, so that the is clear and does not interfere with each other. On the tweeter, an 2-way, 2-inductance design is used to prevent the slight distortion of the caused by resonance.On the is a inductor that passes through the and limits the passage of the treble. In order to prevent the treble from interfering with the , there is also a capacitor-to-ground circuit. Make the more .Solder-free wire terminals correspond to the input and speakers, and the frequency divider can be connected without a soldering iron. Easy to use, speaker DIY upgrade tool.Model: 320Filter characteristics: 2 high and 1 low three-way frequency Impedance: 4-8 ohmsPower: 250WCrossover : 2950HzMaterial: PC+MetalColor: as shownPackage Contents:1 x Frequency DividerOnly the above package content, other are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing.
