1. The three one seven proportional method
This method of positioning refers to dividing the length of the KTV room into three equal parts. The horn is placed at one-third of the length, and the interval between the two speakers is 0.7 times the length of two-thirds of the room. One thing you should pay attention to here is that the speaker should have a slight inward projection angle, but there is no inward projection, and the listening position cannot be placed against the back wall.
2. Three three one proportional method
This method is to divide the length of the room into three equal parts, and the width is also divided into three equal parts. The horn is placed at the first bisector of the length and width. The horn can have a slight inward projection angle, even without inward projection, and the listening position cannot be placed against the back wall. This KTV professional sound placement method looks a bit like the first one and everyone introduced. But they have a certain difference.
3. Screw hole pendulum method
This kind of audio is placed in the room between one-third and one-half of the length of the room, and then the two speakers should be placed on the two sides of the wall as much as possible (if the room is wide, it does not need to be close to the side wall). The inward projection angle of the two speakers is greater than 45 degrees. The listening position should be about 0.5m-1m after the intersection of the projection angle crossing lines.
