【 Weak current College 】 speaker set-up method

1 axis inside method

Pendulum: first of all the speakers in a room of one third to one half the length, and then try to rely on respectively the speakers on the side wall, if the room is too wide, then you do not have to be mounted immediately adjacent side wall. Speaker of the angle is greater than 45 degrees or more, listened to the location where you want two speakers of the projection angle of intersection point after about 0.5-1 meters long.

Effect: If you listen to what complex due to environmental, acoustical asymmetry, a three-pointed star room, the room was too small, and your speakers sound treble sharp, baritone, bass and isn't enough, following the "axis of medial law" will help you.

Second, the equilateral triangle method

Pendulum: the first condition is the speaker you want to leave the back wall (at least 1 metre above) and the side wall (at least 0.5 meters above). The second condition is the second speaker and the listening position as an equilateral triangle. The third condition is the second speaker of inward projection angle to 45 degrees or more. The fourth condition is the equilateral triangle can be. The room is small, after the level does not large squares down; room is big, after the level power large equilateral triangle to expand.

Effect: this is commonly known as of the close method of sound field hearing. Its advantage is that you can reduce the reflection code on shone wall sound direct tone of excessive interference, so get a good sense of orientation as well as the sound field and depth. This is to be able to hear the most, the most direct and most clearly the details of the pendulum. Many commentators in assessing sound like this method.

3. Trinity seven proportion method

Pendulum: the length of the room are divided into three equal division (3), length of the third speaker (a), the interval between two speakers for a room

Two-thirds of the length of 0.7 times (7). Speaker of the best has to have a slightly inward projection angle, but also to internal projection, listen to the location cannot be put on the back wall.

Effect: this method is used to a larger size, the proportion is even (for example 1: 1.25: 1.6 or 1: 1.6: 2.5) of space, can be balanced sound and the sound field and depth.

Four, three, three a proportion method

Pendulum: the length of the room are divided into three equal division (3), the width is also divided into three equal division (3), speaker at length and width of the intersection of the first partition (a). Speakers can have slight inward projection angle, even without inward projection may also be affixed to the listening position rearward wall.

Effect: this method is also used to a larger size, the proportion of space evenly. It and 「three a seven proportion method 」 mentally is consistent, unique and 「three a seven proportion method 」 different is the interval between the two speakers is relatively narrow. This method can also be balanced sound and the sound field and depth.

5. long back wall pendulum

Pendulum: in a rectangular room, generally playing audio experience, will be the short edge to the back wall of sound. But this "pendulum long after the wall" in the opposite direction and, after long side for sound. Speakers want to leave behind the wall at least 1 meter above the speaker and the side wall distance at least half a metre or more. Both the distance between the speaker and the listener's position as an equilateral triangle painted, two speakers of the projection angle in a row is also above 45 degrees to a minimum. Listen to the position is not against the wall, leaving at least a meter distance.

Effect: If you think your audio system, low-frequency quantities are not sufficient, so you can try it now, introduction of the long side of the "speaker swinging" after the wall. But it should be noted that this kind of pendulum on voice as well as gain, while the low-frequency quantities in, a sense of empowerment, but the sound of the sound field has depth will worsen a bit, so to get a balance between these, we should rely on you to play slowly moving distance.

Six or pendulum wall

Pendulum: this is the most ancient of the pendulum. The speaker close to the back wall pendulum, distance back wall 50 cm or 30 cm, 20 cm are okay, go ahead to the deployment. Usually do not need to sound projection angle.

Effect: high-frequency, low frequency of sharp, weak, you can enable frequency and low frequency full up to the high, medium and low frequency can be balanced. However, it also makes sound field of depth, and width is narrow. However, ransacked the shrill sound of two phase balance, sacrifice performance and sound field for a voice like that is the correct approach.

VII. Diamond pendulum

Pendulum method: this method only square space. The square space as diamond, diamond-shaped sound box on the second side of the wall. Speakers behind the diamond sharp corners and listening position behind the diamond tip to do arc or cylindrical acoustic diffusion treatment, should not rely on two speakers too close to the side wall.

Effect: this method of authoritarian square space bass boom of standing wave is too strong. If a square space hate pendulum, it must insert a lot of furniture to 「introduction quell 」 standing wave.

Summary: the above lists the seven most common speaker pendulum, General space you should be able to find the one best suited to your pendulum. The principle of placing the speakers is in any one room space will have a position, a pendulum Act your speakers and room issued most harmonious resonance effect, found that resonate best is what we are after the best positioning of the speakers. Therefore, the speaker set-up are not constant; nor is it necessarily the amount you want to use the ruler to very precise. If you find again the above method results arenot good, then make pendulum. When you find a good location, good method, keep in mind the specific location and display angle, and then fine-tune, then speaker of subtle move becomes very sensitive, by repeated tune after you'll find the ultimate best set-up.
