What are the criteria for evaluating the sound quality of audio speakers?

The criteria for evaluating the sound quality of audio speakers are as follows:

Sound Quality: The most basic and widely used evaluation term for audio equipment.

Tone Color: Sound has a "color" like light. Warmer tone colors produce softer sounds, while colder tone colors produce harder sounds.

Soundstage: This includes the shape of the soundstage, its front-to-back positioning, height, width, depth, and other aspects.

Sense of Layering: This refers to the clarity of sound produced by instruments arranged in a row within the soundstage, as well as the clarity of the spacing between instruments.

Localization of Audio Speakers: Simply put, it refers to the clarity and accuracy of the location of vocal or instrumental sound sources.

Transparency: The best transparency in sound is one that is not piercing and is pleasant to listen to for extended periods. Each person's tolerance for pleasant versus unpleasant sounds varies.

Factors such as the drivers of audio speakers, electronic design, signal processing, power and impedance matching, audio signal quality, tuning, and audio content all affect the sound quality. For example, the signal fidelity of a speaker is an important aspect of sound quality. Some speakers, despite having low power, are expensive because they offer excellent fidelity and resolution. Poor-quality speakers, even when paired with high-end amplifiers, will not produce good results.
