First of all, the speaker should be able to realistically reproduce the instrumental sound and vocals, the more accurate the better. Generally use the piano sound to audition, pay attention to whether the pitch characteristics of the low, medium and high sound ranges change. If you can hear a very independent treble continuously, there is definitely something wrong with this speaker.
2. Listen to the various sound properties of the speakers
Listening to the sound differences in each frequency range in turn: the bass part should be tight, clear and strong, the pitch of the tone is very accurate, there is no bass rumble, sound drag or blur; the vocal and instrumental sound of the midrange should Natural and rich in detail, there should be no feeling of sudden or retracted sound, nor can it be bright or dark; the high-pitched part should be cheerful, light and stretched, and there is no flaw in the harsh or frequent response. Pay attention to the delicate expressions in the music, the process of the disappearance of the piano or cymbal notes, and the details of the atmosphere of the concert hall or jazz club. If the low level details are ambiguous, the speaker lacks clarity, and the low frequency resolution is an important indicator for judging the general "pass" speakers and high quality speakers. Transient response loudspeakers should be able to focus on the transients of the music – from the crisp click of the string drum to the heavy plucking of the guitar – both speed and precision, neither rigid nor excessively flowing or slow dragging The phenomenon. Sound image localization and stage sound (stereo) or sound field reproduction (multi-channel), listen to the sound image carefully, pay attention to whether the instrument sound or human voice comes from a wide stage sound image or a precise position in the three-dimensional sound field? Is it difficult to locate? Of course, this assumes that the speaker is placed properly, and then monophonic listening can be used to determine the speaker's performance in other aspects, because the two-channel performance is easily misleading for its spatial sound field, thus ignoring some important ones. Sound characteristics. Diffusion directivity is to listen to the sound of the speaker at different locations and angles in the room. The vertical diffusion performance is checked by sitting and standing to change the posture. This test method is especially sensitive to changes in high frequency components.
3. Pay attention to the presence or absence of continuous acoustic staining
Some speakers have obvious staining when they are vocalized. This is a kind of sound defect, which is characterized by a superb metal sound superimposed in the high-pitched area, a rough mid-range, and a low-pitched subwoofer. This is evident in poorly designed speakers. If you can hear the above-mentioned staining in the music regardless of the recording content, then this kind of speaker definitely has quality problems.
4. Listen to the speakers with the music you are familiar with
Since the quality of CD recordings varies widely, it is best to bring your own CDs to choose when purchasing speakers. In addition, because the CDs of different recording contents have different characteristics, it is necessary to bring a few CDs with different characteristics to listen to the sounds when listening to the speakers, so that it is easy to compare the real performance of the sound and vocals of the speakers. .
5. Pick the room that best suits your room, equipment, and listening needs
It is best to use the AV receiver or the Hi-Fi amplifier's moderate power to drive it. This is something to keep in mind. In general, the volume of normal listening music is equivalent to less than 10W, and 40W to 100W per channel (excluding subwoofer) is suitable for almost all home theater systems.
6. Pay attention to quality over quantity
You may wish to calm down and listen to different types of speakers with different types of music CDs.
7. To listen to the speaker at the same playback volume
When listening to the comparison of the speakers, it is necessary to make a blind audition comparison at the same volume to get a relatively correct conclusion. Conditional consumers can bring a sound pressure gauge to help you adjust the volume, and the sound pressure gauge is also very useful when setting up the multi-channel speaker system layout.
