What sound characteristics of the speaker should be listened to after the installation and debugging of the speaker? To listen to the main points of the sound, the Chinese Home Theater Network provides the following references:
Uniform uniformity of the sound! Experts believe that this is the first thing, it means uniformity from bass to treble in a wide frequency range.
In fact, it is difficult to judge the tone color as a whole, and we usually divide it into four sub-categories;
The IF is rounded, and this part is dedicated to listening to whether the IF part of the vocal is contaminated by the tone of the speaker - this is a disadvantage of some general speakers.
Low frequency / low frequency is abnormal, this situation is easier to hear. The usual sign is a loud or shallow sound, or a hollow sound.
The fullness of the low-frequency treble , I usually use a collective string performance to test this. The sound of the stringed instrument is not sharp or dry or too sweet. This is the most demanding requirement for the listener, unless you have some experience listening to the band's string group live performance. Due to the acoustic conditions of the hall and the playing style of the band, even the best string groups sometimes have rough or hard stretches. It is necessary to concentrate on listening to whether there is often a harsh or metallic sound, and at the same time pay attention to whether the sound is too full and sounds unnatural. Try listening to a few albums to see if this bad quality is caused by the record itself.
The high frequency is clear, there is almost no sound in most music over 13 kHz. If we do hear the sound of this frequency, it is just a "light flash" instead of a tone. Listening to jazz or rock slaps is an easy way to master this sound. Pop-high rides combine jazz and rock, and recording natural recordings is an excellent test material that includes clean, repetitive momentary treble. You should concentrate on listening to each of these momentary trebles to see if it is dull, too sharp, and blurry. In addition to a few prominent features, HiFi speakers have very good acoustic reduction capabilities. Absolutely good at all the sound effects of "home theater".
The audition standard for a good speaker should be: high-frequency slender and non-stabbing, medium-frequency full and bright, low-frequency, solid, clean, flexible and full of volume.
