Nothing can replace experience, so you should seize every opportunity to listen and compare speakers. Remember, listening to the environment is very important. When listening, you should always use high-quality Power amplifier or receivers and good components to reduce variable factors, but it can ensure that even similar speakers can find the same sound when listening. Compared with amplifiers and phonographs, the sound difference is much greater. If a/b comparison test equipment is used, the equipment has a set of switches directly connected to two groups (or two pairs) of speakers. During the test, please pay attention to the balance comparison, that is, maintain the volume difference between the two groups of test speakers. Within 0.5 dB (only the sound pressure meter can be used here for measurement).
