Full-range speakers have unique advantages, especially in the midrange, because the entire midrange is not split and recombined, but the power amplifier audio is directly input into the voice coil for sound. The low frequency of the full-range speaker performance has been improved. We use deep anodized aluminum cone and 25-core voice coil magnetic circuit to improve the bandwidth and resolution at any cost. This craft The treated aluminum is almost the same as ceramics, and after testing, the resonance frequency can reach 103Hz. Coupled with the combination of rare earth neodymium iron boron strong magnets, it can become a full frequency It is a comprehensive speaker. Advantage: 25 core diversion voice coil Rare earth neodymium boron strong magnet Alumina porcelain cone Powerful. High sound resolution. Good transient control Product specifications: 2.5 inch full frequency Rated power: 20W Impedance: 4 ohm Voice coil diameter: 25mm Resonance frequency: 103Hz Equivalent volume: 1.2L Effective frequency: 103Hz-19.8KHz QTS: 0.83 Sensitivity: 87dB ± 3dB Sound cone material: alumina ceramic Outer diameter: 69mm Diagonal screw hole: 74mm Height: 45mm Opening diameter: 69mm Through-hole diameter: 62mm Features: 1. Anodized aluminum cone Anodized aluminum, also known as ceramic cones, is lighter and thinner than paper cones, yet it is tough, has a wide range of sound, fine vocals, and very high resolution. 2. Rare earth neodymium iron boron strong magnet Rare earth neodymium iron boron strong magnetic power is surging, which guarantees the low frequency volume and strength, and can effectively reduce the distortion at high volume. 3. 25 core voice coil magnetic circuit At present, most 2.5-inch full-range radios on the market are 20 cores, with low power and sound pressure and weak sound. This model not only has a 25-core voice coil magnetic circuit but also uses a short-circuit copper ring design higher than T iron. Clean and unobstructed. Package 2pcs
