How Far Off the Wall Should Acoustic Panels Be?

When it comes to optimizing sound quality in a space—whether a studio, office, or home—the installation of acoustic panels is a smart investment. But one often overlooked factor is panel spacing from the wall. So, how far off the wall should acoustic panels be to maximize performance?

At Guangdong Liyin Acoustics Technology Co., Ltd., we specialize in producing high-performance wood slat acoustic panels with PET felt backing. As a leading exporter in China with a 20,000㎡ modern facility, we combine craftsmanship and science to help clients around the world enhance their acoustic environments.

🎧 Why Panel Spacing Matters

Most people assume acoustic panels should be mounted flat against the wall. While that’s common, leaving a small air gap behind the panel can significantly improve low-frequency absorption. This method is often used in professional sound treatment applications.

📏 Ideal Spacing: The Magic Number

In general, 2 to 4 inches (5–10 cm) of space behind the panel is ideal. This added distance:

• Enhances bass absorption

• Improves overall sound dampening

• Increases absorption without additional material

💡 Pro Tip: A 2-inch panel with a 2-inch air gap performs nearly as well as a 4-inch panel flat-mounted.

🛠️ How to Mount Panels with a Gap

Here are three popular methods to mount wood slat acoustic panels with air space:

1. Wooden Furring Strips: Use wood strips to create a frame behind the panel.

2. Wall Spacers: Install metal or plastic standoffs to keep the panel off the wall.

3. French Cleat System: Great for adjustable mounting with gap control.

Our Liyin panels are engineered to be easy to install with all three methods—gluing, screwing, or using brackets.
