This soundbar was replaced by the Samsung HW-Q990C

The Samsung HW-Q990B is the top-of-the-line offering from the manufacturer's 2022 lineup. With its 11.1.4 setup, it's the next generation of the Samsung HW-Q950A, with a new and improved design overall. It seems more sturdy, with more rumble in the bass right out-of-the-box, and new angled rears that add lots of detail to your favorite movies. It's larger and more expensive than the 9.1.4 Samsung HW-Q930B, with two more channels and a big sub that packs a potent punch in the bass range. As with most Samsung bars, you get access to a wide range of sound enhancement features, so you can customize its sound and pair it with compatible Samsung TVs for extra tools like Q-Symphony.

Our Verdict

8.4 Mixed Usage

The Samsung HW-Q990B is great for mixed usage. This 11.1.4 bar offers versatile performance, with a neutral sound that makes it suitable for everything from vocal-centric TV shows to music to movies. You have access to lots of customization tools, making it easy to adjust the bar's sound based on your preferences. Its rear speakers bring an immersive quality to the sound, so audio seems like it wraps all around you. There's good height, especially with Dolby Atmos content, bringing a cinematic experience right to your living room. It's a great bar, but its premium price tag may not be ideal for everyone.

Pros
  • Room correction available.
  • Graphic EQ and presets.
  • Impressive Atmos performance.
  • Bluetooth, Wi-Fi, Apple AirPlay support.
Cons
  • No Chromecast capabilities.
8.6 Dialogue/TV Shows

The Samsung HW-Q990B is amazing for dialogue-heavy TV shows and podcasts. It's an 11.1.4 setup, so there's a discrete center channel included to improve vocal quality in the mix. With its balanced mids, voices are clear and detailed, so you don't have trouble following the action on your screen. You can even use its 'Voice Enhance' dialogue enhancement tool if you wish. When it comes to podcasts, you have lots of wireless streaming options, from Bluetooth to Wi-Fi. However, without Chromecast support, it doesn't fit as easily into your Google ecosystem.

Pros
  • Room correction available.
  • Bluetooth, Wi-Fi, Apple AirPlay support.
Cons
  • No Chromecast capabilities.
8.4 Music

The Samsung HW-Q990B is great for music. Like most premium bars on the market, it has room correction tools to optimize the audio reproduction based on your room's unique acoustics. With it on, the frequency response is neutral, especially in the mids, where most voices and lead instruments reproduce. It's suitable for listening to many different genres, and the extra punch in the bass range brings bass-heavy genres like EDM to life. If you prefer a different sound, many customization tools are available, including a 7-band graphic EQ and bass and treble adjustments.

Pros
  • Room correction available.
  • Graphic EQ and presets.
Cons
  • No Chromecast capabilities.
8.3 Movies

The Samsung HW-Q990B is great for movies. With its two surround speakers, you get a really immersive feel with lots of common audio formats, from 5.1 surround sound like Dolby Digital to object-based formats like Dolby Atmos. Sound effects are clear and detailed, with audio stretching all around you, so you really get the sense that you're sitting in the middle of your favorite movies. The sub provides plenty of rumble in the bass, so your chair shakes during intense scenes as if you're in a cinema.

Pros
  • Room correction available.
  • Extended low-bass.
  • Impressive Atmos performance.
Cons
  • No Chromecast capabilities.

Differences Between Sizes And Variants

The Samsung HW-Q990B is available in 'Black'. You can see the label for the model we tested here.

If you come across another version of this soundbar, let us know in the discussions, and we'll update our review.

Compared To Other Soundbars

The Samsung HW-Q990B is a premium bar suitable for everything from movies to music to TV shows. It'll please most types of listeners, although it doesn't give the same immersive soundstage as other premium offerings like the Bose Smart Soundbar 900 with Speakers + Bass Module or the Sonos Arc with Sub + One SL Speakers. It's bigger than the Samsung HW-Q930B, with a little more rumble in the bass and added features like additional side-firing drivers in the satellites. If its hefty price tag isn't to your liking, the Q930B is a solid alternative at a more affordable price.

Samsung HW-Q990C

The Samsung HW-Q990C is the next generation of the Samsung HW-Q990B, and while they're both very premium models that can please many different listeners, the next-gen model is better overall. The bars have a similar look and a similar sound, though the Q990C's bass is a bit more controlled out-of-the-box. As a result, you notice a more balanced thump and rumble in the bass.

Samsung HW-Q990D

The Samsung HW-Q990D is a couple of generations newer than the Samsung HW-Q990B. Both bars may look very similar, but some features give the Q990D a leg up over its predecessor. Most importantly, it supports HDMI 2.1, so you can send 4k signals at 120Hz, making it great for gaming. It also has a couple of additional sound features like Private Listening, which limits the bar's sound to the satellites for a less intrusive listening experience, and Sound Grouping, which lets the satellites play left and right channel content for a more stereo sound.

Sennheiser AMBEO Soundbar MAX

The Sennheiser AMBEO Soundbar MAX and the Samsung HW-Q990B are two very different soundbars. They're both premium setups with Dolby Atmos support, but the Sennheiser is a standalone bar, as opposed to the Samsung, which has a subwoofer and satellites. The Samsung's a more versatile pick, with more bass out-of-the-box and a better soundstage. It's better for surround sound and Dolby Atmos content, with more enhancement features on hand. If you don't have room for a sub and satellites, the AMBEO is a good alternative. Its large, heavy design isn't for everyone, though.

LG S95QR

The Samsung HW-Q990B and the LG S95QR are both very premium setups with versatile performances. However, the Samsung soundbar is better overall. Its default sound is more neutral, which less boominess in the bass and more detail in the treble. Its surround sound and Atmos performances are better, too, so sound effects in your movies are more clearly and accurately reproduced. You can customize the LG with its bass and treble adjustments, but the Samsung is more customizable with its graphic EQ.

Klipsch Cinema 1200

The Samsung HW-Q990B is better than the Klipsch Cinema 1200. The Samsung is a better-built setup, and its surround sound and Atmos performances are better. As a result, sound effects in your favorite movies reproduce more clearly. There are more sound enhancement features, too, thanks to its room correction feature, and unlike the Klipsch soundbar, it supports DTS content. The Klipsch is still a really good bar, but it's not quite as versatile as the Samsung.

JBL Bar 1000

The Samsung HW-Q990B is better than the JBL Bar 1000, though both of these premium soundbars offer different strengths. The Samsung is better-built, with built-in voice assistant support. It has more sound enhancement features, including bass and treble adjustments, and it gets louder overall. The JBL still gets quite loud and supports third-party voice assistant devices. Plus, the JBL's smaller, detachable satellites might be better suited for your living space.

Samsung HW-Q930B

The Samsung HW-Q990B and the Samsung HW-Q930B are the top-of-the-line offerings from Samsung's 2022 lineup—and you can't go wrong with either bar. The Q990B is the best of the bunch. It's an 11.1.4 setup with two more channels and a bigger design that brings a little more punch in the bass range. The Auto EQ allows you to adjust its subwoofer's reproduction based on your room's acoustics, which the Q930B lacks. The extra two channels don't make much difference in the sound. You can still get an awesome sound with the Q930B for less.

Samsung HW-Q950A

The Samsung HW-Q990B is the next generation of the Samsung HW-Q950A, and it's a better bar overall. They're both 11.1.4 setups, but the Q990B packs more punch in the bass range right out of the box. It has an improved design, too, with metal grilles that feel more solid than the 950A's fabric sides. Its redesigned satellites add a lot to the sound, especially if you watch a lot of movies. It gives a more immersive listening experience overall.

Bose Smart Soundbar 900 with Speakers + Bass Module

Whether you choose the Bose Smart Soundbar 900 with Speakers + Bass Module or the Samsung HW-Q990B, you won't be disappointed. They're both really premium setups with versatile performances overall. The Bose is a 5.1.2 setup that has a wider, more immersive soundstage with stereo content. However, the 11.1.4 Samsung comes with more channels, including two up-firing drivers on its satellites, so it has a slightly more cinematic sound. It also has more sound enhancement features on hand.

Sonos Arc with Sub + One SL Speakers

The Sonos Arc with Sub + One SL Speakers and the Samsung HW-Q990B are both premium soundbars with impressive performances, so you can't go wrong with either choice. The Sonos is a 5.1.2 setup with a wider soundstage with stereo content. While the Sonos doesn't bring as much bass right out of the box, you can easily use its bass and treble adjustments to get a similar response to the Samsung. That said, it doesn't have as many channels as the 11.1.4 Samsung. Given the additional up-firing drivers on the Samsung's satellites, you notice more sound effects in the space around you.

Samsung HW-Q910B

The Samsung HW-Q990B is better than the Samsung HW-Q910B. The Q990B is Samsung's most premium offering from 2022 and has a better performance. Its satellites don't need to be wired to a receiver module to work, and they come with up-firing speakers, so the bar's Atmos performance is better. Also, it comes with the Auto EQ subwoofer correction feature, which the Q910B lacks.

Samsung HW-Q800B

The Samsung HW-Q990B is better than the Samsung HW-Q800B. The Q990B is a 11.1.4 setup compared to the 5.1.2 Q800B. That means that it has more channels, including two satellites included in the box. Its Atmos and surround sound performances are better overall, resulting in a more clear and real feel.

JBL Bar 9.1

The Samsung HW-Q990B and the JBL Bar 9.1 are both very premium Dolby Atmos setups—however, the Samsung is better overall. The Samsung has better performances with surround sound and Dolby Atmos content, so sound effects in your favorite movies reproduce more accurately. It has more sound enhancement features, including a graphic EQ to customize its sound.

Sony HT-A7000 with Speakers + Bass Module

The Samsung HW-Q990B is better than the Sony HT-A7000 with Speakers + Bass Module. The Samsung has better surround sound and Dolby Atmos performances, meaning that sound effects are more clear and present in the mix. It gets louder with less compression at max volume, too. With its graphic EQ, it's more customizable, too. The Sony is still a very premium bar with a versatile performance.

Samsung HW-Q950T

The Samsung HW-Q990B is a bit better than the Samsung HW-Q950T. The Q990B is a newer bar with more features, including room correction to optimize the sound based on your room's unique acoustics. Its surround sound and Atmos performances are better, so sound effects reproduce more accurately in your favorite movies. The Q950T is still a really good bar, so you can't go wrong with either pick.

Samsung HW-Q900A

The Samsung HW-Q990B is better than the Samsung HW-Q900A. The Q990B has discrete satellites, so it has better surround sound and Atmos performances. It's better built, with more low-bass in the mix to help you feel the thump and rumble in action-packed scenes. The Q900A is a good alternative if you don't have space for rear speakers, though. Also, you can always add speakers separately if you want to improve its performance.

Samsung HW-Q90R

The Samsung HW-Q990B is a bit better than the Samsung HW-Q90R. The Q990B has more sound enhancement features, including a room correction mode to optimize its performance based on your room's acoustics. Its performance with surround sound and Dolby Atmos content is better, too, so sound effects reproduce more accurately. It supports Apple AirPlay 2, too, and there's built-in voice assistant support, unlike the Q90R. The Q90R is still a versatile bar, so you can't go wrong with either pick.

Sonos Beam (Gen 2) with Sub Mini + One SL Speakers

The Samsung HW-Q990B is better than the Sonos Beam (Gen 2) with Sub Mini + One SL Speakers. They're both very premium soundbar setups with Dolby Atmos support. However, the Samsung soundbar supports more audio formats and more wireless playback options and offers more sound enhancement tools. Also, the larger Samsung gets louder with less compression at max volume. Subjectively, we found that it did a better job replicating height with Atmos content, resulting in a more immersive, all-around sound.

Samsung HW-Q800A

The Samsung HW-Q990B is better than the Samsung HW-Q800A. The Q990B comes with rear speakers, so it offers better surround sound. Its Atmos performance is better, too, making it a better choice for watching movies. There are also more customization tools on hand, including room correction. The Q800A is a good alternative if you don't have space for rear speakers or if you don't watch a lot of movies.

Sony HT-A9 with Bass Module

The Samsung HW-Q990B and the Sony HT-A9 with Bass Module are two very different setups. They're both very versatile Dolby Atmos soundbars, and the Sony soundbar's unique speaker design means that you can place them anywhere in your setup, resulting in a better soundstage. That said, the Samsung soundbar reproduces more low-bass. It gets louder, and there's less compression at max volume, too. With its discrete center channel, the Samsung soundbar's vocal reproduction is better, too. Both bars will please most listeners, but your personal preferences will decide which is best for you.

LG SP9YA

The Samsung HW-Q990B is better than the LG SP9YA. The Samsung comes with rear speakers, meaning its surround sound performance is more clear and real. Its Atmos performance is better, so sound effects reproduce more accurately in the mix. There's even a graphic EQ on hand, which makes it more customizable than the LG. However, if you don't have room for rear speakers in your room, the LG is still a versatile alternative.

LG SP11RA

The Samsung HW-Q990B is better than the LG SP11RA. The Samsung has better surround sound and Atmos performances, so sound effects are more clear and real in the mix. Its default sound is a bit more neutral, without the extra boominess of the LG. With its graphic EQ, it's more customizable, too. That said, the LG's bass and treble adjustments still allow you to get a similar sound to the Samsung.

The Samsung Q990B has an impressive stereo frequency response. Its balanced mids and treble make it suitable for listening to lots of different types of audio content, as voice and lead instruments reproduce with clarity and detail. There's plenty of rumble in the bass, especially compared to last year's Samsung HW-Q950A. You feel the thump in the bass, especially with bass-heavy genres like hip-hop and EDM, so it seems less controlled than with next generation's Samsung HW-Q990C.

In addition to a 7-band graphic EQ, you have some EQ presets to help you customize its sound. When listening to music, audio sounds pleasant on 'Standard' mode. However, 'Adaptive Sound' makes audio seem more diffused, almost as if it's been forced through a filter. 'Adaptive' is more suitable for listening to movies, while 'Standard' is better for music and other stereo content.

If you prefer a more neutral sound with stereo content, you can set the Samsung Q990B's bass to '-3' and its treble to '0'. The sound is more balanced, and you notice less boom in the bass range. Voices and lead instruments remain clear and present in the mix, too.

It's worth mentioning that if you're in 'Standard' mode, the EQ preset for treble doesn't affect the frequency response, so if you're using this setting, you'll only be able to change the bar's sound with the bass EQ. That said, you can always take advantage of the 7-band graphic EQ in the app for more robust sound customization.

The Samsung Q990B has a good stereo soundstage performance. It has good focus, meaning that it's easy to pinpoint sound effects to pinpoint locations around you. For example, if you listen to an orchestral recording, each instrument seems to come from a particular spot on stage. On 'Standard' mode, the soundstage is about as wide as the bar itself, but unlike the Bose Smart Soundbar 900 or the Sonos Arc, it doesn't have any tricks to make it seem wider than that. The soundstage is a little wider on 'Adaptive Sound', but it seems more diffused, and audio is forced towards the back wall. In our view, 'Standard' is the better choice for stereo content overall, but your subjective impressions may vary.

The Samsung Q990B has an amazing center channel performance. It's an 11.1.4 setup, meaning that it comes with a discrete center channel to help improve vocal quality.

The Samsung Q990B has a great surrounds performance. It comes with two discrete surround speakers, which offer a more clear and real representation of sound effects in the space around you. For example, if you watch a car chase scene, cars seem to race from one location to another. Audio stretches all around you, rather than sounding like it's just coming from a speaker placed in front of you.

The Samsung Q990B has up-firing drivers built into the bar and the satellites, which bounce sound off the ceiling and back down towards you to create the impression of height. With its balanced frequency response, sound effects reproduce with detail and accuracy.

Subjectively, the Samsung Q990B offers a similar Atmos performance to the Samsung HW-Q930B—making it one of the best bars for movies we've tested to date. On its 'Adaptive Sound' mode, details are especially crisp, and you hear dialogue with great clarity. The sub adds plenty of rumble in the bass, so you feel your chair shake with intense movie scores and action-packed scenes. The bar does a good job representing height, and sound stretches all around you. It performs well in 'Standard' mode, too, but the details aren't quite as impressive as with 'Adaptive Sound'.

The Samsung Q990B has a fantastic selection of sound enhancement features. You have a lot of tools on hand if you want to change up its sound, including bass and treble adjustments and a 7-band graphic EQ. There are many EQ presets, too, including 'Standard', 'Surround Sound', 'Game', and 'Adaptive Sound'. Like most premium offerings, there are features to optimize its audio reproduction based on your room's unique acoustics. The first is called SpaceFit Sound, and it adjusts the bar's sound. Auto EQ, meanwhile, controls the subwoofer's output.

Like many other manufacturers, Samsung offers a feature that lets you pair the bar with a compatible Samsung TV—it's called Q-Symphony. Essentially, it synchs the bar with your TV, so your TV speakers play along with the bar itself. Unfortunately, we found that it doesn't have a real impact on the sound. Audio's a little louder, and there's a touch more height, but you have to really focus to notice it. Of course, this is a subjective opinion, and your own preferences as well as your room setup will impact how you perceive the change in sound quality.

Audio latency is decent over an ARC connection. Some apps and TVs compensate for latency differently, but overall, the audio you hear is in sync with the video you see. Audio latency is a little higher with certain formats like Dolby Digital, but you can always use the bar's AV Sync feature to manually compensate for delays if needed.

Audio latency is decent over HDMI In. You're more likely to notice lip-synching issues with some audio formats like Dolby Digital and Dolby Digital Plus, which are common on lots of streaming platforms. Of course, some apps and TVs will compensate for this differently, and the AV Sync feature is always on hand in the app if you need to adjust the delay manually.

Audio latency is very good over an Optical connection. It falls on the higher side with formats like Dolby Digital, but you can always use the AV Sync feature in the app to adjust the delay accordingly. Some apps and TVs compensate for latency differently, too.

The Samsung Q990B can passthrough some of the highest-quality bandwidth signals, meaning you can connect the bar between your TV and your PC for clear and crisp text on screen. There's Dolby Vision Passthrough support, too. Unfortunately, you can't passthrough 4k @ 120Hz but the later generation of this soundbar, the Samsung HW-Q990D, supports this feature.

The Samsung Q990B lets you wirelessly playback audio from your mobile devices over a Bluetooth, Wi-Fi, or Apple AirPlay 2 connection. Samsung's Tap Sound feature is another way to play audio from your phone on the bar. It works through Bluetooth, so you tap your compatible phone against the bar to get it to play audio from your phone. It's handy, but if your phone isn't compatible, you can still just stream audio wirelessly via Bluetooth. You can also check your country's product page to see if Chromecast is supported in your region.
