DTS:X vs. Dolby Atmos
The latest surround sound formats
Dolby Atmos and DTS:X are two new popular surround sound formats. Both add overhead sound effects to deliver surround sound with greater realism than older formats. How do they compare?
Dolby Atmos and DTS:X add overhead sound effects for an immersive home theater experience.
Dolby Atmos and DTS:X soundtracks are recorded and mixed using a technology known as “object-based” surround sound. This means that the filmmaker can place individual sounds anywhere in your listening space and move them around in three dimensions. With older surround formats, sounds can move front to rear and left to right, but not up and down.
Dolby Atmos is already in use in hundreds of movie theaters. It’s also supported by a wide selection of home theater components. There are Atmos-compatible receivers and Atmos-enabled speakers available. There are even sound bars equipped with Atmos technology.
In early 2015 DTS launched DTS:X, and it quickly gained a foothold in some movie theaters. Soon thereafter, it began to appear in home theater receivers.
Many A/V receivers offer both Dolby Atmos and DTS:X processing. The speaker wiring is the same for both formats.
What do I need to play Dolby Atmos and DTS:X?
Dolby Atmos and DTS:X are quite similar in their object-based approach to surround sound. The two formats are also pretty close when it comes to the gear you need to enjoy them in your home:
- Both formats require an A/V receiver or a preamp/processor with built-in decoding. Many receivers offer both Dolby Atmos and DTS:X processing. So in most cases that means there’s no need to make a choice. Simply get a receiver that decodes both formats and you’re all set.
- A Blu-ray player or streaming device (like the Apple TV 4K) that supports your desired format. Some streaming devices may support Dolby Atmos without offering support for DTS:X. Give us a shout if you want help matching up gear.
- Two HDMI cables. One to connect your A/V source to your receiver, and another to go from your receiver to your TV. Learn more about choosing HDMI cables here.
- A surround sound speaker system.
Dolby makes specific speaker recommendations for Atmos to achieve optimum performance. This includes a standard 5.1 or 7.1 surround speaker system, plus at least one pair of “height” speakers. The height speakers can be either in-ceiling, or upward-firing Atmos enabled speakers.
Upward-firing speakers bounce sound effects off of the ceiling and down to your listening position. They're an easy add-on to an existing speaker system.
DTS:X has no official requirements for the number of speakers or their locations in your room. Simply arrange your speaker system to best fit your space. Then let the receiver’s auto-calibration and object-based surround processor sort out the details. It will determine where to best send dialogue and sound effects.
DTS:X also lets you manually adjust sound objects. You can boost hard-to-hear dialogue above other sounds in your center channel. That’s a big plus over simply turning up the center channel volume.
Do you plan to enjoy both Dolby Atmos and DTS:X within the same speaker system? If so, you'll want to align your speaker setup according to the Atmos specs.
What content is available with Dolby Atmos and DTS:X soundtracks?
Want to breathe new life into your existing movies, video games, and music? Both Dolby Atmos and DTS:X can “upconvert” your content. The improved sound will play through all of the speaker channels in your system. The effect is not as dramatic as a true object-based soundtrack, but it’s a lot of fun!
Which way to go?
So which of these new surround formats should you pick? We recommend you get a receiver that has both Dolby Atmos and DTS:X capability. Then you will enjoy the widest variety of movies with the best surround sound available.
