DTS:X vs IMAX Enhanced: Which Soundbar Format Is Better?

What DTS:X does for a soundbar

DTS:X is an object-based audio format, much like Dolby Atmos. Instead of sending sound to fixed channels, the format describes each sound as an object with a position in a three-dimensional room. The soundbar decodes those objects and assigns them to its available drivers, including virtual height and side channels.

The practical benefit is that a bar with DTS:X can create a sense of overhead sound without any physical ceiling speakers. The bar uses its own drivers and digital processing to aim sound around the room. That is why we cover DTS:X in detail in our soundbar audio formats article, and why it is a different question from virtual surround sound, which can work even without an object-based codec.

For a fuller comparison with the rival codec, see our DTS:X vs Dolby Atmos article.

What IMAX Enhanced actually is

IMAX Enhanced is not a separate audio codec. It is a certification program that a soundbar can earn when it meets certain performance targets and includes DTS:X decoding. When you see the IMAX Enhanced logo on a bar, it means the maker has worked with the program to deliver a specific sound profile tuned by IMAX.

That tuning takes the form of an IMAX signature sound mode. When you play a movie that is mastered in IMAX Enhanced, the bar switches to this mode to reproduce the mix with a more theatrical presentation. The goal is to match the balance and dynamics the director and engineers intended for a large theater.

Because the program builds on DTS:X, every IMAX Enhanced soundbar is also a DTS:X soundbar. The reverse is not true: many DTS:X bars have no IMAX Enhanced certification. If you want the full explanation of how this relates to DTS Virtual:X, see our DTS Virtual:X soundbar article.

How they compare on a soundbar

On a soundbar, the most important difference is what the two labels tell you about hardware. DTS:X support tells you the bar can decode object-based audio and place sounds in space. IMAX Enhanced tells you the bar has been certified to reproduce a specific IMAX tuned profile, and it guarantees DTS:X support as part of the deal.

In practice, this means a bar with only DTS:X will play standard DTS and DTS:X soundtracks in a virtualized surround field. A bar with IMAX Enhanced adds the signature mode for IMAX Enhanced masters, which are available on select discs and streaming titles. The bar also needs to detect that the content is IMAX Enhanced and switch modes automatically.

The quality of the result depends on the bar's driver array and processing, not just on the logo. A soundbar with physical rear speakers will create a more convincing surround field than a single bar, as we explain in our soundbar channel numbers article. If you are choosing between a 3.1 bar and a 5.1 bar, see our 3.1 vs 5.1 comparison.

• DTS:X is the codec: it carries the object audio data.
• IMAX Enhanced is the certification: it adds a tuned mode and requires DTS:X.
• A bar can be DTS:X only, or DTS:X plus IMAX Enhanced.
• Neither label changes how the bar connects to your TV; both work over HDMI.

Which one matters for your purchase

If most of your viewing is streaming and standard Blu-rays, DTS:X support is the feature that will actually matter. It gives you object-based audio on titles that carry a DTS:X mix, and it also handles older DTS soundtracks well. The IMAX Enhanced signature mode is only useful when you watch content mastered in that format, which is a smaller catalog.

If you are a movie collector who buys UHD Blu-rays, many of which carry IMAX Enhanced versions, then the certification is worth seeking out. The signature mode can make those discs sound closer to the theatrical mix. But if you are just looking for a good surround experience from a single bar, DTS:X decoding plus a solid driver array will serve you better.

For any of these options, the physical setup matters as much as the codec. A bar with up-firing speakers will do more with height cues than one without, and adding rear speakers will improve the surround field. If you are pairing the bar with a TV, also check that your TV can pass through DTS signals over eARC; some TVs only carry stereo over ARC.

What to pick for your use

Questions

Do I need IMAX Enhanced for DTS:X to work?

No. DTS:X works on any soundbar that decodes the codec. IMAX Enhanced is an add-on certification that includes DTS:X support, but a bar without the IMAX logo can still play DTS:X soundtracks.

Does IMAX Enhanced make every movie sound better?

No. The IMAX signature mode is designed for content mastered in IMAX Enhanced. On other content, the mode may do little or nothing, depending on how the soundbar applies it. Many bars leave it off unless they detect IMAX Enhanced content.

Can a soundbar with DTS:X but no physical height speakers create overhead sound?

Yes. DTS:X uses object-based positioning and the bar's drivers to create virtual height cues. The effect is usually less convincing than physical up-firing or ceiling speakers, but it is a real surround sensation.

Is DTS:X the same as DTS Virtual:X?

No. DTS:X is the object-based codec. DTS Virtual:X is a post-processing mode that creates a virtual surround field from non-object audio, like stereo or 5.1 soundtracks. Many bars support both. See our DTS Virtual:X article for details.

Should I choose a soundbar based on IMAX Enhanced over DTS:X?

No. Choose the bar that has the driver layout, channel count and connections that fit your room and TV. IMAX Enhanced is a nice extra, but DTS:X is the codec that matters for object audio compatibility.

How do I know if my TV passes DTS sound to the soundbar?

Check your TV's audio output settings. Many TVs only output stereo over ARC, unless they support eARC and have a pass-through option for DTS bitstream. See our HDMI ARC vs eARC article for guidance.
