In fact, in many people's audiovisual rooms, the system does not produce satisfactory sound. A basic problem is that the speaker is not positioned correctly. Finding the correct position for your speaker is the most important basic factor for the system to produce good sound.

The key to achieving the best sound effect is to reduce the interaction between the speaker and the room, thereby optimizing spectral balance, low-frequency sense, sound field depth and width, mid frequency domain clarity, and imaging.

1. The relationship between speakers and listeners
The listener should sit in the middle of two speakers, and the distance from the speakers should be slightly larger than the distance between the two speakers. The more open the speaker is, the wider the sound field. However, if the speaker is too open, the middle sound image will weaken. If the spacing between speakers is too narrow, the width of the sound field will shrink. When using a multi unit speaker, you should try to stay as far away from the speaker as possible, so that the sound of each unit can blend together. If the distance is too close, there will be a significant difference in the coordination of high, medium, and low frequencies.

2. The amount of bass affected by being close to the wall
First of all, would you like to mention whether your speaker is a bass reflex or a sealed speaker. The low-frequency reflex speaker must be kept away from the rear wall, and the sealed speaker is relatively unrestricted. If the speaker placement in your room is limited and cannot be far from the back wall, you need to determine which speaker is more suitable for your room. Some speakers are designed to be close to the back wall to enhance the natural coordination of high, medium, and low frequencies. If these speakers are far from the back wall and close to the center of the room, the sound will become thinner. Proper placement not only extends the low-frequency response of the speaker to achieve natural attenuation, but also avoids peak and concave frequencies, making the bass smoother. Improper positioning can lead to uneven frequency response, generating standing waves, and rendering bass. The result will be a strong bass energy, with less mid to high energy. The distance between the speaker and the side wall will affect the reflection of sound. The closer it is to the side wall, the more reflected sound will reach the listener. This is not a good thing, it will affect the positioning of the image.

3. The distance from the back wall affects the expressive power of the sound field
Usually, the farther the speaker is from the back wall, the deeper the sound stage. A deep and wide sound field is rarely produced on speakers near the back wall. Unfortunately, many audiovisual rooms cannot keep the speakers away from the back wall. If the speakers must be near the back wall, the back wall needs to be diffused. In principle, the stronger the back wall, the better.

4. The location of the listener in the room
When you hear resonance in the room, you need to constantly move the listening position back and forth to find a better position without resonance. When you find the most flat position, you can achieve a smoother bass while also hearing improvements in clarity and resolution of the midrange.

5. The coordination between listening height and high, medium, and low pitches
When the seat height changes, it will affect the balance of high, medium, and low frequencies, rather than the bass. Specifically, when your ears are at the same height as the treble unit or on the axis of the treble unit, the speaker's sound is the brightest (with the highest amount of treble). The degree of change due to high pitch can vary greatly depending on the ability of different speakers to spread high pitch. Some speakers have a great tolerance, and when you change the height, you can only hear small differences.

6. Speaker tuning angle
Internal angle adjustment refers to pointing the speaker unit directly towards the listener. The angle of intonation affects many aspects of music expression, including the balance between mid and high notes, the focus of the sound stage, the sense of space, and direct notes. Most speakers have the brightest sound when directly on the axis. An excessively bright speaker can be tamed with the speaker facing forward (the angle of the speaker's internal tuning should not be too large).

When the width of the audiovisual room is insufficient, there is a clear benefit of angle adjustment, as the reflected sound on the side wall will be greatly reduced due to the angle adjustment of the speaker. On the contrary, reducing the angle of intonation and utilizing reflected sounds enhances the sense of space and air. There are too many angles to adjust the focus of the sound, but the sound performance is often too bright. There is no angle intonation, and the high notes are smoother, but the sound and image positioning are more blurry. The amount of angle adjustment depends on the speaker, room, and personal preferences.
