How to choose the sound family cinema? The formation process of home theater, each part has to be selected, the most important thing is to be with the perfect, so as to reach the best state, then in the form of how to select the audio home theater?
1, the quality of test frequency
Low frequency inferior speaker generated can be deaf ears if detonation, but is completely that bloated pine thick, the lack of a sense of hierarchy and strong feeling. Good low frequency should be clean and crisp, clear level, don't do things sloppily, even though a variety of low frequency instruments such as drums, bass guitar and Piano size bass, can easily distinguish. So don't be fooled by the low frequency quantity feeling inferior, low frequency as clean sound natural and comfortable.
2, if the voice test
The human voice is the most often hear the merits, not difficult to detect, pay attention to voice any unusual nasal or be pursed her lips in a sound feeling. Some speakers "sound the same box" will greatly interfere with intermediate frequency, make this band sound vague. If the sound to dye relative to other frequency sound staining is more serious, because the majority can hear sound frequency, or frequency of music are concentrated in the intermediate frequency range, which almost all kinds of music, will be a replay of the barrier.
3, flexible testing high frequency sensing
Inferior frequency is ear piercing shriek, hear head headache, extreme cases to bel canto violin or soprano become sharp noise brake. Similarly, different textures of different instrumental treble in the multi generation, good treble can tell. The most difficult to master key is, good treble is not back a listen in awe of pores is erect, also is not heard the more tired, and this is the cotton toughness and elastic, smooth and level, high to the highest point can be easily heard does not produce sound.
4, test of high volume and sound field junction like
Some speakers expressed stably in the low volume, but in volume ascend to a certain index will be distortion, or "shot", the emergence of various non music signal in the recording (with 12 points but volume for testing safety standards). Specifically, if the orchestral music is like one kind of music, you must pass this pass. The speaker standard to a certain extent do voice from the box, to create a sound field and the junction of clear image, showing different instrument point position and texture, there is plenty of diffusion and growth, the width and the height but audio space.
Soft and endings should be clearly heard, while in large volume and "bursting" without distortion, vocals and instruments sound not inextricably. The quality of the replay can appear Fengrun music sense and sense of air, and the notes of the jumping ability, like clouds and see the blue sky, showing the whole carefully ordered video. More directly in long ears listen to is not tired.
