1. Create a high-quality frequency divider to truly restore the sound details, so that you can feel the immersive and 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. Ingenuity, full of materials. Every component has been carefully . From material selection to finished products, every process is strictly controlled. Every component has been tested and repeatedly, just to achieve better sound quality. 4. If you want your audio details to be excellent, the layering will be more clear and prominent; choosing it is equivalent to choosing a surprise. 5. The special capacitor for frequency division of polypropylene film and the high temperature resistant winding inductance coil are used to its super load-carrying power, long-term durability, and very good sound quality Product Description: Model: 338 Maximum power: 200W Low frequency response: 45Hz High frequency response: 20KHz Applicable impedance: 4-8 ohms Suitable for 2.5-8 inch size: 8 x 5.8 x 2.8cm Material: plastic colour: As shown Package Contents: 1 x Bass Divider Only the above package content, other products are not included.
