1. Home theater upgrade HIFI high-fidelity frequency point adjustable components use professional audio components, high-strength 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. Bass inductance + polymer magnet to enhance the sinking of the bass, reasonable circuit + high-quality components + high cost performance = correct sound 3. 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. 4. If you want your audio details to be excellent, the sense of hierarchy will be more distinct and prominent; choosing it is equivalent to choosing a surprise. 5. The frequency divider special capacitor and high temperature resistant wire inductance coil are used to its super load-carrying power, long-term durability and very good sound quality Product Description: Model: 338 Maximum power: 120W Low frequency response 45Hz High: 20KHz Applicable impedance: 4-8 ohms Suitable for speakers 8 inches (including 8 inches) size: 110 x 67 x 24mm Material: plastic colour: Package Contents: 1 x 1 high 1 medium 1 low 3-way frequency divider Only the above package content, other products are not included.
