Behind-the-speaker clarifies each sound.
Three-panel (behind-the-speaker) improves localization of vocals.
Right-and-left-wall for primary reflection clarifies sound resonance.
Back-wall increases resonance, making it ideal for listening to classical music, for example.

Flutter echo: mid and high-frequency sounds reverberate with a distinct “beeeeen” sound

This phenomenon occurs in a relatively wide area across two parallel walls and can be observed by clapping your hands.

Flutter echo can occur in a setting like this.
The problem can be resolved by placing acoustic conditioning panels as shown here.

Boomy bass (standing wave distortion): bass sounds leave a lasting “boom boom”

According to room size, low-frequency bass sounds will expand or be diffused into certain parts of the room, such as the corners, resulting in boomy bass.

*Standing waves occur in various parts of a room according to room shape, the position of the speakers, and other conditions. To hear how standing waves affect bass sounds, play some music and walk around the room, listening from different places.

Excessive reverberation

Use the guide below to determine how many panels are needed to counter excessive reverberation:

Room Area 20m2(215.2ft2 15m2(161.4ft2 10m2(107.6ft2
Number of Yamaha Acoustic Conditioning Panels 12 or more 9 or more 6 or more

*Ceiling is 2.4 m high.

Panels in a 16.5m2 (177.6ft2) room
Panels should be evenly aligned and installed vertically.
When the ceiling is 3 m or higher, the panels should be installed in two rows.
