What’s the Optimal Configuration for a Small Home Theater with Dolby Atmos Sound?

If you’re looking to create a cinematic experience in your home, one of the key elements that you’ll need to consider is sound. You could have the biggest, brightest screen with the most vibrant colors, but if your sound is lacking, you’ll never get that fully immersive experience that you’re looking for. That’s where Dolby Atmos comes into play.

Dolby Atmos is a revolutionary sound technology that creates a multi-dimensional sound experience, moving around you in a three-dimensional space. It is not limited to a simple left, right, or center audio channel. Instead, it envelops the listener in a 360-degree aural experience.

This article will guide you through creating the optimal setup for a small home theater system with Dolby Atmos sound. We will talk about the best speakers to use, the way to position them for the best surround sound experience, and how to configure them with your home theater system.

Choosing the Best Speakers for Dolby Atmos

The foundation of any impressive home theater system is the speakers. For a Dolby Atmos setup, you will need to consider both the quality and type of speakers. The Atmos system supports up to 128 audio tracks and up to 64 unique speaker feeds. However, for a small home theater, a 7.1.2 or a 5.1.2 system will suffice.

A 7.1.2 system includes seven horizontal speakers, one subwoofer, and two overhead or upward-firing speakers. A 5.1.2 system, on the other hand, consists of five horizontal speakers, one subwoofer, and two overhead or upward-firing speakers. The overhead speakers are crucial in providing the height dimension of sound that distinguishes Dolby Atmos from other audio technologies.

When choosing your speakers, you should consider factors like the size of your room, the audio quality of the speakers, and your budget. Floor-standing speakers are great for a larger room, while bookshelf speakers can work well in a smaller space.

Positioning the Speakers for Optimal Surround Sound

The speaker positioning is another critical aspect of your Dolby Atmos home theater setup. Your speakers should be placed in a way that maximizes the sound coverage in your room. The aim is to create a setup where you’re enveloped by sound from all directions, adding a sense of realism to the audio experience.

For the conventional speakers in a 5.1.2 or 7.1.2 configuration, the front left and right speakers should be positioned at an angle of 22 to 30 degrees from the center of your main viewing position, creating an optimal triangle. The center speaker should be aligned with the center of your screen. The surround speakers should be placed at an angle of 90 to 110 degrees from your main viewing position, while the rear speakers, in a 7.1.2 setup, should be positioned at an angle of 135 to 150 degrees.

As for the overhead speakers, they should be positioned directly above or slightly ahead of your main seating position. The aim is for the sound to come from above, providing the height effect that Dolby Atmos is known for.

Configuring Your Home Theater System

Once you have selected your speakers and positioned them properly, you need to configure your home theater system. This involves connecting your speakers to an AV receiver that supports Dolby Atmos. The receiver will act as the hub of your home theater system, receiving inputs from audio and video sources, decoding the Dolby Atmos sound, and sending the signals to the respective speakers.

After connecting the speakers, you should configure the settings on your AV receiver to match your speaker setup. You should specify the number of channels, the type of speakers, and their placement. If your AV receiver has a calibration feature, use it to automatically adjust the sound levels for optimal performance.

Integrating Dolby Atmos with Your Screen

The final aspect of your Dolby Atmos home theater setup is integrating the sound with your screen. After all, the purpose of a home theater system is to create a harmonious blend of picture and sound.

Your screen should be placed at a comfortable viewing height, with the center aligning with your eye level when seated. It should also be positioned at a distance that is approximately three times the height of the screen. This will ensure that you have a comfortable viewing experience and that the sound from the front speakers does not seem disconnected from the screen.

Furthermore, you should ensure that your screen and your AV receiver are compatible. This means that they have compatible inputs and outputs, support the same resolution, and can handle the same frame rates.

In conclusion, creating an optimal setup for a small home theater with Dolby Atmos sound involves choosing the right speakers, positioning them for optimal surround sound, configuring your home theater system, and integrating the sound with your screen. With a well-executed setup, you can bring the magic of the cinema into your home, no matter how small your room may be.

Selecting the Right Equipment for Dolby Atmos Home Theater

The equipment you choose for your home theater is just as crucial as the speaker setup. Finding a high-quality AV receiver and Blu Ray player that support Dolby Atmos technology is essential.

When choosing an AV receiver, remember that it will act as the ‘brain’ of your home theater system. Hence, you need one that can efficiently decode Dolby Atmos sound to send to your speakers. Some of the features to look for in an AV receiver include multiple HDMI inputs, compatibility with 4K and HDR content, and support for streaming services.

Your Blu Ray player should also be Dolby Atmos compatible. It should be able to handle 4K Ultra HD Blu Rays and support HDR. This will ensure that you can enjoy high-definition video along with your immersive Dolby Atmos sound.

In addition to the AV receiver and Blu Ray player, if you want to stream content, make sure you have a streaming device compatible with Dolby Atmos. Many of the popular streaming services like Netflix, Amazon Prime, and Disney+ offer Dolby Atmos content, but you’ll need a device that can handle it.

Incorporating Dolby Atmos Enabled and Overhead Speakers

The distinguishing feature of Dolby Atmos is its ability to create a sense of height in the sound, which is achieved through the use of overhead speakers or Dolby Atmos enabled speakers. These speakers are crucial in creating the three-dimensional sound experience that Dolby Atmos is known for.

Overhead or ceiling speakers are installed in the ceiling and direct sound downwards, creating the illusion of height. On the other hand, Dolby Atmos enabled speakers (also known as height speakers) are special speakers that project sound upwards, where it then reflects off the ceiling and comes down at the listener.

When incorporating these speakers into your setup, remember to position them correctly. Overhead speakers should be installed directly above your seating area or slightly in front of it. Dolby Atmos enabled speakers should be positioned at ear level for the best results.


Building a small home theater system with Dolby Atmos sound can seem like a daunting task. However, with the right speaker setup, equipment, and room configuration, it’s entirely achievable. When selecting your speakers, remember to consider both the type and quality. Ideal positioning for your speakers is essential for optimum surround sound. Your system’s configuration should include a Dolby Atmos compatible AV receiver and Blu Ray player. Don’t forget to incorporate overhead or Dolby Atmos enabled speakers for that distinct three-dimensional sound. Once all these elements come together, you can sit back, relax, and enjoy the immersive cinematic experience right in your home. No matter the size of your room, with careful planning and the right choices, you can create a home theater system that rivals any cinema.
