When it comes to setting up a professional recording studio or a home studio, one of the most critical aspects to consider is the placement and treatment of studio monitors. Studio monitors are designed to provide accurate and uncolored sound reproduction, allowing audio engineers and musicians to make informed decisions about their mixes. However, the environment in which these monitors are placed can significantly impact their performance. One often-overlooked aspect of studio monitor placement is what to put behind them. In this article, we will delve into the importance of treating the space behind studio monitors and explore the various options available to enhance sound quality.
Understanding the Importance of Acoustic Treatment
Acoustic treatment refers to the process of controlling the behavior of sound within a given space. This can involve absorbing sound waves, diffusing them, or redirecting them to minimize unwanted reflections and resonances. When studio monitors are placed in a room without proper acoustic treatment, sound waves can bounce off nearby surfaces, including the wall behind the monitors, and return to the listener’s position. This can cause a range of issues, including comb filtering, which results from the interference of direct and reflected sound waves, leading to an uneven frequency response.
The Impact of Rear Wall Reflections
Reflections from the rear wall can be particularly problematic because they can combine with the direct sound from the monitors, causing cancellations and reinforcements at different frequencies. This can make it difficult for engineers to accurately assess the balance and tone of their mixes. Furthermore, rear wall reflections can also contribute to a phenomenon known as standing waves, where sound waves reflect back and forth between parallel surfaces, creating areas of high and low sound pressure. Standing waves can lead to an uneven bass response and can make the room sound “boomy” or “dead” in certain areas.
Assessing Your Studio Space
Before deciding what to put behind your studio monitors, it’s essential to assess your studio space. Listen to your monitors in the room and pay attention to any areas where the sound seems uneven or colored. You can also use measurement tools, such as a real-time analyzer (RTA) or acoustic measurement software, to identify problem areas. By understanding the specific acoustic challenges of your room, you can tailor your treatment approach to address these issues effectively.
Options for Treating the Space Behind Studio Monitors
There are several options available for treating the space behind studio monitors, each with its own advantages and considerations. The choice of treatment will depend on the specific needs of your studio, the size and shape of the room, and your personal preferences.
Absorptive Panels
One of the most common approaches to treating the space behind studio monitors is to use absorptive panels. These panels are designed to absorb sound waves rather than reflect them, reducing the amount of energy that bounces back into the room. Absorptive panels can be made from a variety of materials, including acoustic foam, fiberglass, and mineral wool. They can be mounted directly on the wall behind the monitors or placed on stands to create a more flexible treatment arrangement.
Diffusive Panels
In addition to absorptive panels, diffusive panels can also be effective in treating the space behind studio monitors. Diffusive panels work by scattering sound waves in different directions, rather than absorbing them. This can help to reduce the coherence of reflections, making them less problematic. Diffusive panels can be particularly useful in rooms where a high degree of absorption might make the space sound too “dead.”
DIY Solutions
For those on a budget or looking for a more DIY approach, there are several options available. One simple and effective solution is to use thick blankets or moving pads to create makeshift absorptive panels. These can be hung on the wall behind the monitors or draped over a frame to create a more structured treatment. Another DIY approach is to build your own absorptive panels using materials like OWENS CORNING 703 or ROXUL SAFE’n’SOUND, which can be purchased at most hardware stores or home improvement centers.
Implementing Your Treatment Plan

When placing absorptive or diffusive panels behind your studio monitors, it’s essential to position them in a way that maximizes their effectiveness. As a general rule, panels should be placed at a distance of 1-2 feet behind the monitors, depending on the size of the room and the type of treatment being used. It’s also important to ensure that the panels are securely mounted to the wall to prevent them from falling or shifting over time.
In terms of the amount of treatment needed, this will depend on the specific requirements of your room. As a general guideline, it’s recommended to treat at least 10-20% of the total surface area behind the monitors. However, this can vary depending on the severity of the acoustic issues in your room and the type of treatment being used.
Combining Treatment Approaches
In many cases, the most effective approach to treating the space behind studio monitors will involve combining different types of treatment. For example, you might use absorptive panels to address low-frequency issues and diffusive panels to control midrange and high-frequency reflections. By combining different treatment approaches, you can create a more comprehensive and effective treatment plan that addresses the unique acoustic challenges of your room.
Monitoring Your Progress
As you implement your treatment plan, it’s essential to monitor your progress and make adjustments as needed. Listen to your monitors regularly and pay attention to any changes in the sound. You can also use measurement tools to assess the effectiveness of your treatment and identify areas where further improvement is needed. By taking a systematic and iterative approach to acoustic treatment, you can optimize the sound quality in your studio and create a more accurate and enjoyable listening environment.
