In addition to the projector, the home theater sound system is one of the necessary conditions for building your own home theater. As for how to install the home theater sound system, many people tend to put some mistakes in the installation of the sound system, and some of the mistakes I sorted out below may be quite common.
"Pre" and "mid" home theater speakers
From the perspective of professional home theater, there is no need to distinguish the front and center speakers, all of them should use the same loudspeaker, and the installation method should be the same, the advantage of this is to ensure the continuity of sound flow, consistent voice color, consistent sound characteristics and accurate positioning.
In the actual use environment, because the environment is not allowed, the construction is complex, and the cost is high, and the transparent screen cannot be used, the speaker in the middle has to be taken out separately and installed above or below the screen. It's called "center" when it's taken out from the front speaker alone. To a large extent, watching the movie is to "tell" the story, that is, the dialogue between the characters in the movie. This part can even account for 80% of the whole movie, and it all depends on the central speaker to restore. So don't save money on a mid speaker. Try to use the first three speakers of the same grade, and try to install them at the same height. If the front speaker and the center speaker cannot be on the same horizontal line, it is also recommended that the angle between the front speaker and the sofa should not exceed 10 degrees, so as to avoid poor sound coherence.
It is recommended that the front speakers be installed at the middle height of the curtain, or flush with the ear height of the listening position (about 1-1.2m), to avoid being too close to the ceiling or the ground, to accentuate the acoustic staining, and to ensure the accuracy and continuity of the acoustic image positioning.
5.1 home theater has no back surround
Because there is no rear surround in the 5.1 home theater sound system. This misunderstanding also directly affects the early wiring and even speaker installation, that is to say, many people have installed surround speakers behind the sofa. For example, in the non living room open environment (both sides of the sofa are the corridor and balcony curtains of the dining room, resulting in no position to hang surround speakers on both sides of the sofa), 5.1 in the home theater system, the surround speakers are generally hung on both sides of the sofa, with the sofa as the central axis and the central speakers at 90-110 degrees, which can bring more accurate audio-visual positioning, while hanging on the back wall can only be said to be a compromise Method, even in this case, we should try to draw close to the marked angle as much as possible, and try to pull away from both sides. At the same time, we should pay attention to avoid the aggravation of acoustic staining caused by too close to the side wall.
Don't point the surround speaker at your ears
Because surround speaker mainly provides surround sense, once the surround speaker is too close to the listening position or the level is too high, it is easy to destroy the surround sense. In the traditional channel based home theater sound system, the height of the surround speaker thx is recommended to be about 600mm higher than the ear, that is, about 1.6-2m from the ground.
In the latest 3D sound effect technology Dolby panoramic sound system, the surround speaker should not be hung high, otherwise it will be confused with the top sound field and the effect will be greatly reduced.
