2PCS HiFi 4 inch Tweeter Speaker Unit 25-core Black Silk Membrane 8OHM 30W Home Film Treble Loudspeaker B1-103S

【Description】: The sound is mellow and crisp, with a sweet timbre. It is a high-performance tweeter with a high cost-performance ratio. The craftsmanship is exquisite, and the sound is clear and crisp. It features a dual-magnet design with anti-magnetic properties. The recommended crossover point is above 2.8 kHz. It is recommended to pair it with a crossover of 2 or higher. The diaphragm is made of pure natural 25mm black silk, providing a delicate, mellow and sweet sound quality. A: The voice coil is made of all copper wire, while most on the market are aluminum coils. The treble sound is purer than that of ordinary tweeters. B: A certain proportion of imported special liquid magnet (magnet fluid) is added, making the sound more silky and smooth, eliminating noise. The physical properties are conducive to the lubrication and heat dissipation of the voice coil, making it more heat-resistant, increasing the magnetic flux lines, and allowing the sound to be more natural. 【Usage Note】: This tweeter is generally used with a corresponding crossover. If there is no crossover, simply connect a capacitor in series (theoretically, it is better to connect it to the positive terminal). For example, 2.2, 3.3, 4.7, or 5.6 uf. The smaller the capacitance, the higher the crossover point and the smaller the sound. The resistance in series can be within the range of 1.2 to 6.8 ohms. Commonly, 2.2 or 3.3 ohms are used. The larger the resistance value, the greater the attenuation and the smaller the sound.
