How to choose a good speaker?

When people are choosing speakers, they usually requires the "HIFI" funtion, then what is "HIFI"?

 

HIFI: High-fidelity, so how to define this word?

The most high-fidelity sound should be the sound of the master tape which was recorded by some professional recording equipment in the recording studio. However, the sound could be heard normally is just the digital music. As follow is the production process of digital music: playing and multi-track recording, material handling, mixing, and mastering. So that the material handing and mixing inssue in great changes to the original sound durling this pricess.

 

In addition to HIFI for choosing a good speaker, what kind of funtions or features should be paied attention to?

 

Frequency: The different frequencies of sound should be heard  according to priority.

To take an example as a full range Speaker like Sanway VT4888 Three Way Line Array Speaker. When you are hearing the bass, it should be compact and clear,but not humming. What's more, as a major part of the music, mid voice is more important.The sound of vocal and instrumental music should be natural, micromesh, and may not be too loud or muffled, not too bright or light.

In this part of Frequency, there are different emphases in different sounds. For example, as a powered subwoofer like VT4880 or   VRX918S, we should foucs on the bass of the speaker; but if there is a  full range speaker like L-1 or L-2, we should pay attention to the frenquency balance.
