Samsung HW-Q800C Picture

The Samsung HW-Q800C is a 5.1.2 Dolby Atmos soundbar released in 2023 as the next generation of the Samsung HW-Q800B. It's a more affordable alternative than the manufacturer's flagship models, including the Samsung HW-Q990C. While it has many of the same features, it lacks satellites, which is ideal if you're low on space in your living room. If you own a compatible Samsung TV, you can hook up the bar to enjoy Q-Symphony, which the manufacturer advertises to create a more immersive sound. Built-in Alexa offers hands-free control, too.

Our Verdict

N/A Mixed Usage

The Samsung Q800C is great for mixed usage. This 5.1.2 Dolby Atmos soundbar offers a versatile performance overall, so it's suitable for everything from music to movies to TV shows. Dialogue in your favorite shows is clearly and accurately reproduced, as are voices and other instruments in music. The sub brings the rumble in action-packed scenes and bass-heavy music genres. There's support for many different audio formats, too. However, more immersive surround sound formats like Dolby Digital aren't quite as clear and real as that produced by bars with discrete satellite speakers.

Pros
  • Extended low-bass.
  • Lots of sound customization tools.
  • Dolby Atmos support.
Cons
  • No satellite speakers.
N/A Dialogue/TV Shows

This soundbar is excellent for dialogue-centric content like sitcoms and podcasts. It's a 5.1.2 setup with a discrete center channel that's designed to improve vocal quality in the mix overall. As a result, it's easy to follow along with conversations taking place on screen. The bar comes with two dialogue enhancement tools: a more traditional Voice Enhance mode and an Active Voice Amplifier designed to analyze the sounds of your room to adjust the voices in the mix accordingly.

Pros
  • Lots of sound customization tools.
  • Lots of wireless playback options.
Cons
  • Compression at max volume.
N/A Music

The Samsung Q800C is great for music. This soundbar offers many premium sound enhancement features, including a room correction tool called SpaceFit Sound that optimizes its output to your room's unique acoustics. The resulting sound is very even and balanced, with clear and accurate reproduction of voices and lead instruments in the mix. The sub also brings all the rumble in bass-heavy genres like EDM and hip-hop. Customization is easy with the bar's 7-band graphic EQ, too, available in Standard sound mode.

Pros
  • Extended low-bass.
  • Lots of sound customization tools.
  • Gets loud.
Cons
  • Compression at max volume.
N/A Movies

The Samsung Q800C is great for movies. This soundbar supports many audio formats commonly found on streaming platforms and Blu-rays, including Dolby Digital and Dolby Atmos. It reproduces clear dialogue, and the sub brings excitement to action-heavy scenes. Without satellite speakers, though, the bar can't stretch sound effects all around you for a clearer and more real feel to your audio content. You can always add compatible satellites separately, which is a nice touch.

Pros
  • Extended low-bass.
  • Lots of sound customization tools.
  • Dolby Atmos support.
Cons
  • No satellite speakers.

Differences Between Sizes And Variants

This soundbar is available in Black; you can see our model's label here.

If you come across another version of this soundbar, let us know in the forums so we can update our review accordingly.

Compared To Other Soundbars

The Samsung Q800C is a mid-range 5.1.2 soundbar with a versatile overall performance. It lacks satellites, so it doesn't bring the same immersive feel to surround sound compared to premium models like the Samsung HW-Q990C, but this can be a positive if you're low on space in your living room. It still has good sound quality and offers many of the same premium features as other models in the manufacturer's lineup, like Q-Symphony and SpaceFit Sound room correction.

You can also see our recommendations for the best soundbars, the best Dolby Atmos soundbars, and the best Samsung soundbars.

Samsung HW-Q800B

The Samsung HW-Q800C is the next generation of the Samsung HW-Q800B, and it's a bit better overall. These two setups have no major differences, though the Q800C has a slightly improved overall sound. It gets louder, with a touch less compression at max volume, too.

Samsung HW-Q900C

The Samsung HW-Q900C is a more premium alternative to the Samsung HW-Q800C—notably, the Q900C is a 7.1.2 setup with two additional surround channels compared to the 5.1.2 Q800C. You notice this difference with surround sound and height content, as the Q900C brings a more immersive sound. It gets louder with less compression at max volume, too.

LG S90QY

The Samsung HW-Q800C is better than the LG S90QY. The Samsung soundbar has a more neutral sound out-of-the-box, which is more suitable for some listeners. It also has a graphic EQ, which gives you more control over its sound compared to the LG. Plus, it's better built. 

Samsung HW-Q990C

The Samsung HW-Q990C is the manufacturer's flagship model and offers better performance than the Samsung HW-Q800C overall. The main difference between these models is that the Q990C includes satellite speakers, so it has a better performance with surround sound. Up-firing drivers on the satellites bring a more immersive feel to Atmos content as well. Plus, the bar gets louder and has less compression at max volume.

Samsung HW-Q800A

The Samsung HW-Q800C is a newer iteration of the Samsung HW-Q800A, offering slightly better overall performance. The Q800A is an older model with a 3.1.2 setup, meaning it has to downmix surround sound into stereo to play it. The 5.1.2 Q800C, however, has side-firing drivers to bring a more realistic feel to the sound. It's better built, too, with more enhancement features such as room correction.

The bar has a similar design to the previous Samsung HW-Q800C. It's a sleek plastic soundbar with metal grilles covering the bar's front, sides, and top. The physical controls are on top of the bar, and the inputs are underneath.

The bar is rather long, so it doesn't fit between the legs of an average 55" TV. It isn't very tall, so unless your TV sits flush on your table, your screen isn't obscured.

Build Quality

The Samsung HW-Q800C has excellent build quality. The bar itself has a solid and durable feel. It's mostly made of plastic, and the metal grilles covering the bar help to protect the drivers inside. The wooden sub feels sturdy, too. However, the fabric circle covering one side is prone to collecting dust and debris over time.

The bar has a great stereo frequency response. Its room correction feature puts it on par with other premium models on the market, as it automatically optimizes the bar's sound based on your room's unique acoustics. With it on, you get a good, well-balanced sound, especially in the mids, where vocals and lead instruments are reproduced. The sub brings plenty of rumble in the bass, too, and while it struggles with very low-bass on some tracks, it's not very noticeable to those who aren't avid audiophiles. Overall, it's suitable for listening to lots of different audio content.

We recommend using the bar's default settings if you prefer a more neutral sound with stereo content. However, as you can see here, our treble level adjustment didn't change the bar's sound when on Standard mode. We aren't sure if this issue is unique to our model, but you can leave a comment in the forums if you experience a similar issue.

The Samsung HW-Q800C has a good stereo soundstage. The soundstage is perceived to be about the size of the bar itself, and the bar is rather wide, to begin with. Plus, focus is very good. This means that instruments are clearly separated into the left or right channels based on how the original audio engineers mix the audio.

This bar's distortion falls within good limits at a normal listening volume. There's a small jump when you push it to max volume, which is typical, but it's still hard to notice with real-life content. This means that audio reproduction is clean and pure overall.

The Samsung HW-Q800C is a 5.1.2 soundbar, and it comes with a discrete center channel to improve vocal reproduction in the mix.

The Samsung HW-Q800C uses two side-firing drivers built into the bar to simulate a phantom surround sound. Since the frequency response on these channels is quite even, sound effects are clear and easy to hear. However, a phantom surround doesn't provide as clear or real a feel as you find with discrete satellite speakers like those with the Samsung HW-Q990C. You can always add a compatible model to the bar separately.

The Samsung HW-Q800C uses two up-firing drivers built into the bar to bounce sound off the ceiling for the illusion of height. The frequency response on these channels is even, though it falls below our target curve, so some effects are less clear in the mix. It doesn't come with rear speakers, so unless you add them on separately, you don't notice the same all-around feel with sound effects.

Subjectively, we found the bar provides a pleasant listening experience. Details are crisp and clean in the mix, so you notice sound effects with clarity. The sub provides good rumble in the bass, too. As expected, though, there's only some feeling of height, but you don't get a very overhead feel, especially compared to more premium bars like the Samsung HW-Q900C or the Samsung HW-Q990C. For example, a helicopter flying overhead seems like it's coming from a place in front of you instead.

The bar comes with lots of different enhancement features. Like many premium bars on the market, it has a room correction feature designed to optimize its sound based on your room's unique acousticsโ€”it's called SpaceFit Sound. If you prefer to manually adjust the bar's sound, a 7-band graphic EQ is available on Standard mode, as well as bass and treble adjustments. The treble adjustment tool didn't work for us on Standard mode. If you watch a lot of dialogue-heavy content, you can use the Voice Enhance feature to enhance dialogue or the Active Voice Amplifier tool, which analyzes noise in real-time to ensure voices remain clear in the mix. If you choose to add rear speakers separately, their levels are adjustable, too.

This soundbar has a good latency performance.

Latency can vary, though, of course. The Audio Sync feature is designed to manually adjust for the delay, so if you have any issues, you can use this tool to adjust it on your own.
