1. Home theater upgrade HIFI high-fidelity frequency point adjustable components adopt professional audio components, high-intensity combination, create high-quality frequency divider to truly restore the details of the sound, so that you can feel the immersive shocking sound effect 2. Applicable to: 4-8 ohm frequency divider/power 250W 3. Bass inductance + polymer magnet to enhance the sinking of the bass, reasonable circuit + high-quality components + high cost performance = correct sound 4. The role of ingenuity is full of materials. Every component has been carefully . From material selection to finished products, every procedure is strictly controlled. Every component is after repeated tests, just to achieve better sound quality. 5. The switching frequency point is adjustable. The old crossover is rigid. After the user installs it, sometimes the sound quality is not suitable. It is difficult for beginners to solve it. Even if a new crossover is replaced, it may not be suitable. The cost is high, and this frequency divider adds a treble point adjustable function, which can meet the needs of more people and adapt to more speakers.
