professional audio components and high-intensity combination are used to create a high-quality crossover that truly restores the details of the sound, allowing you to feel the immersive and shocking sound effect.<br> 3 high-temperature-resistant inductors. The inductors are fixed with and glue for high-temperature-resistant audio to prevent resonance.<br> On the treble line, the treble circuit is composed of capacitors in series and inductance to the ground, and the switch can adjust the volume.<br> The material is sufficient, the treble is clear and bright, the midrange 10 microfarads filter out the bass and the inductance connects in series to filter out the treble, so that the treble and bass cannot pass through, and it is compatible with midrange speakers between 3 inches and 6.5 inches.<br> Solder-free wire terminals correspond to the input, treble, midrange, and bass speakers, which means that the frequency divider can be connected to it without a soldering iron. The material is sufficient and easy to use. It is a powerful tool for speaker DIY upgrades.<br> Model: 3003<br> Filter characteristics: 1 high, 1 medium, 1 low three-way frequency<br> Power: 250W<br> Impedance: 4-8 ohms<br> Crossover point: Bass/midrange 850Hz, treble/midrange 2 ways, 200Hz-5500Hz switch adjustable<br> Size: 138 x 90 x 33mm<br> Material: PC+Metal<br> Color: as shown<br> Package Contents:<br> 1 x Frequency Divider<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing.
