In the sound system, the structure of the speaker is the simplest, but the role played is the most important. The speaker is the final link in the sound system and is the key device for converting electrical signals into sound signals. Due to the lack of structural components of the speaker, this leads to any lack of performance that affects the entire replay. However, the evaluation of the speaker is generally based on subjective listening - the final music replay is good or bad. Therefore, the following first problem arises: This is the unified problem of the technical test and subjective sound quality evaluation of the speaker.
First, on the measurement and listening of the speaker
Friends with certain HiFi experience will have such a consensus: this is the gap between the technical indicators of the speakers and the subjective audition.
Why is this happening? This is to start from the beginning, from the main technical indicators of the current speaker test.
Among the technical specifications of the speaker, the most important ones are as follows: this is the frequency range, withstand power, sensitivity and phase characteristics, and transient characteristics.
The frequency range, also known as the frequency response, refers to the replay range from bass to treble in the speaker. At some point, the frequency response of a pair of small civilian speakers and a pair of large monitors may be consistent; however, the perception of subjective listening is quite different. This in the end is why? Is it because the test is not accurate or is someone deliberately making a fake? Under normal circumstances, the above speculation is not correct, but for other reasons.
