1. Frequency response range. This value is generally as wide as possible, but it should be noted that many companies do not mark +/-3db or +/-6db, so you can mark the frequency response range as you like or mark it wider than the actual value. many. The requirement of hifi speakers is +/-3db. This requirement is not low. For AV speakers, this requirement is generally not met. Many boxes can only meet the level of +/-6db. Better speakers can meet the level of +/-2db within a certain range. This requirement is very high, and only a few top passive speakers can achieve it. Although active speakers can be achieved with DSP, they also introduce more distortion;
2. Impedance. This value is generally 4 ohms, 6 ohms and 8 ohms. Boxes with other impedances are currently very rare in the market. Generally speaking, 8 ohms is better to push, and the requirements for power amplifier control are lower. It mainly requires high power. 4 ohms are used more on AV boxes, because in this way, relatively low-power AV power amplifiers can also emit louder sound; 6 ohms is in the middle, and now this impedance speaker is more and more popular.
3. Sensitivity. Sensitivity is a bit more complicated. Generally speaking, if other conditions remain the same, the higher the sensitivity, the better it will be. But for speakers of different calibers and different crossovers, this value cannot be simply compared. Sensitivity is not as high as possible, nor is it as low as possible. It's not suitable either. In short, you can't judge the quality of speakers based on sensitivity, you can only roughly judge whether the speakers are good to push, and they must be in the same caliber.
4. Weight Generally speaking, good boxes are usually heavier. The box is heavier, the resonance is generally lower, and the low frequency is clearer and cleaner. However, many brands will retain part of the resonance to achieve their own unique sound style, and some brands use several material composite panels and some low-resonance materials, which can also achieve low resonance when the cabinet is lighter. Adding a metal plate to the panel will increase the cost a lot, but it is very helpful to improve the resonance of the box, and it can achieve lower resonance without much increase in weight.
