Room Analysis Results
Your home theater room is too small for all the energy your electronics will produce. I am hoping you have no subwoofers in your room. Lots of energy within your room means lots of low-frequency issues below 100 Hz. The only way to manage those low-frequency issues, and all we can do is to manage in your small room, is to use diaphragmatic absorption. It is the most powerful of all the low-frequency absorption technologies and is represented in our ACDA units. It is all about getting as much low – frequency coverage since we don’t have enough space to achieve a complete solution. We must manage within the space provided which is always along each wall surface.
We line each wall surface area with a combination of our ACDA -10 and ACDA -12 units. Where to place them is easy. The answer is everywhere we can within the room. We will place the ACDA -12 along the front and rear wall and the ACDA -10 along each side wall. This will provide low-frequency absorption from 30 – 50 Hz. where it is required and then a more broadband approach from 30 – 200 Hz. for the side walls. If you had room on the ceiling, we could treat that. However, most of the times it is better to find another room size and volume for your home theater than to spend the money and time treating the ceiling with low-frequency absorption.
We have to stay with absorption in your small room size and volume. We do not have the distance for diffusion to work within. On the face of each ACDA unit is our foam technology. It starts at 100 Hz. and goes through 6,500 Hz. With the low-frequency, carbon, absorption starting at 30 Hz. and going to 50 Hz., we then add the foam technology to create a broadband, absorption curve that starts at 30 Hz. and goes through 6,500 Hz. with the ACDA – 10. Both of these absorption curves will assist your small room size and volume home theater usage. If you must have a subwoofer, make sure the driver diameter does not exceed 6″ or 150 mm.

Room Zones Explained
Red Zone
The red group are rooms that produce so many low, middle, and high frequency energy issues, that large amounts of absorption treatments are required. There is not enough space for diffusion in terms of surface area or distance for wave lengths to fully form. It is the room sizes that are below 2,000 cu. ft. in total volume. The large amounts of treatment surface area, especially in the lower frequencies, will take up so much space that you might not be able to work in it.
Yellow Zone
The yellow group of room sizes is from 2,000 – 4,000 cu. ft. This group has the necessary space to allow for enough low, middle, and high frequency absorption along with enough space for diffusion. You have the space to place the appropriate low frequency absorption technologies and enough distance for diffusion to work. You will still have issues, especially in the low end but they can be predicted and managed.
Green Zone
The third group (green) of room sizes and volumes is greater than 4,000 cu. ft. It is an ideal grouping of width, height, and length to allow for almost any usage wanted. These rooms have enough distance to allow for appropriate management of all reflection time signatures, unwanted modal pressures, along with enough distances to allow for diffusion to do its job correctly and allow for all diffused sound wave forms to fully form.

Next Steps
Recommended Acoustic Treatment & Placement
Red zone rooms are too small for multiple sound sources found in home theaters. If you must use this room for home theater, no more than a 5.1 system with no subwoofer. Use the ACDA-10 units for the side walls and the ACDA -12 units for the front and rear walls
