Samsung’s HW-Q9990H might not exactly reinvent the wheel where the brand’s flagship soundbars are concerned, but it still manages to find a couple of small improvements to what were already the finest full surround soundbar in town

• Exceptionally powerful, detailed sound
• Outstandingly immersive surround sound experience
• Good for music too

• Not as tidy as a single bar soundbar
• Vocals can be a touch ‘hard’
• Premium price

• 

• A separates system in a single box With its three-channels-each rears, 9-channel soundbar and dual-driver subwoofer this Samsung is a one-box sound system

• Great for music and movies Can upmix stereo to full surround is impressive.

• Easy to set up The auto-calibration system works constantly, and the control app is available on phones and tablets

While Samsung’s four-piece flagship models are usually the biggest head-turners in the brand’s annual soundbar range refresh, I was also charmed this year by Samsung’s remarkable HW-QS90H – an incredibly powerful and flexible single-bar soundbar capable of reallocating its drivers to different channels depending on whether it’s hung flat on a wall or sat flat on the table. In fact the QS90H just picked up our soundbar of the year award.

This does not mean, however, that 2026’s flagship HW-Q990H has somehow dropped the ball. On the contrary, while it isn’t packed with new innovation like the QS90H does, it does manage to be (a bit) better than its predecessor. Which is saying something when that predecessor was already as good as a soundbar gets.

• Four piece system
• Pleasing industrial sculpting and finish
• 11.1.4 channel delivery

The HW-Q990H comprises of four matching speaker components: The main bar that sits underneath your TV, two rear speakers with drivers built into their top, outer side and front edges, and a more or less cubic soundbar with two large drivers on opposing sides.

All the components really do look like they belong together, and while accommodating four separate components in your room is obviously more of an imposition than a single bar or bar-plus-subwoofer soundbar solution, Samsung has managed to keep all of the package’s elements pretty compact considering how big a sound they’re able to produce.

The front edge of the main bar carries a welcome LED display while the bar’s hard black plastic finish and angular sculpting, with its ‘sharp’ edges and double-angled left and right ends, creates a dramatic industrial look that’s much easier on the eye than my description makes it sound.

The second generation of Samsung’s new dual-port subwoofer is one of the most compact and attractively finished subwoofers in the soundbar world, and even the rears manage to add some further angular style to the system.

• 11.1.4 channels

The single most appealing feature of the HW-Q990H is its monster 11.1.4 channel count. This isn’t unique any more, but as we’ll see, Samsung uses it more effectively than anyone else when it comes to creating the sort of seamless hemisphere of sound around the viewer required to deliver full immersion with Dolby Atmos and DTS:X sound mixes.

The full surround Dolby Atmos and full DTS:X experience is backed up by an impressive real-time up-mixing option that can convert even basic stereo mixes into a multi-channel sound experience capable of using all of the system’s channels.

Set up and system optimisation with the Q990H comes from both SpaceFit Sound Pro auto-calibration that continually monitors the sound so that it always appears to its best advantage, and an AI bass management system that’s constantly monitoring the bass input from the 300W subwoofer to ensure its contributions don’t become too heavy, too light or too distorted.

The LED display on the soundbar’s front keeps you informed on what sound format, input and volume you’re using, and is backed up by excellent Samsung Sound and Samsung SmartThings apps that make it easy to both control the soundbar with a visual interface and add extra Samsung Music Studio speakers and multi-room set ups to the soundbar if 11.1.4 channels just aren’t enough for you.

It’s possible through these apps to set up a personal listening mode where the sound is played exclusively through the rear speakers so as not to disturb others in the house late at night, and a party sound grouping mode that syncs the rear and front speakers so music plays the same from all directions. There’s also an option to turn the subwoofer off, leaving the soundbar to do all the bass work, which could again prove helpful if you want to reduce the system’s impact on a late-night household.

An AI Adaptive feature tries to automatically optimise the soundbar’s playback characteristics to suit the sort of sound source you’re watching (sports footage, movie, news broadcast etc), plus there’s a dedicated Game Pro mode that emphasizes the directionality of the system’s sound so you can more easily place where enemies/rivals might be approaching from.

The Active Voice Amplifier feature can automatically ramp up dialogue in the mix if a lot of ambient noise is detected in the room, while a new Sound Elevation system can physically lift the height of the sound so that it tallies up better with either a TV that’s positioned unusually high above the soundbar, or a screen that’s so big that its heart is also significantly above the position of the soundbar.

• Two-in, one out HDMI loop-through
• 4K/120Hz

The Q990H’s connectivity is impressive. Where physical jacks are concerned, the highlight is a two-in, one out HDMI pass-through system capable of supporting Dolby Vision and HDR10+ HDR signals, as well as 4K/120Hz.

This means you can connect your console or PC directly to the soundbar and pass the video through to your TV – handy for set ups that have issues such as drop outs or audio delay while using the eARC system.

The bar does also support that eARC HDMI system, though, if you prefer to route all your sound through your TV’s connections, while an optical digital audio input is on hand as a non-Atmos/DTS:X input option.

The Q990H also supports wireless Bluetooth and Wi-Fi music streaming with integrated support for Spotify Connect, Tidal Connect, Apple AirPlay, Alexa voice support, and ‘works with’ support for Google Home and Google Cast.

Two final connectivity features are the ability to receive Dolby Atmos mixes wirelessly from compatible Samsung TVs (though only in a lossy format) and Samsung’s Q Symphony feature, where the soundbar can share speaker duties with compatible Samsung TVs, rather than the soundbar simply taking over from the TV’s speakers.

• Spectacular power and detail
• Works for movies and music

Samsung itself admits that it hasn’t made any significant alterations to the hardware of the Q990H compared with its Q990F predecessor. While the tech fan in me always loves innovation, it’s hard to blame Samsung for largely sticking for the Q990H with a formula that earned pretty much universal acclaim last time round.

Not surprisingly given the similarity of its hardware DNA, the Q990H displays all the strengths of the previous model. Starting with the creation of a pretty much flawless hemisphere of sound around your viewing sweet spot.

The up-firing channels in the front and back speakers meet perfectly to create the top of the Dolby Atmos sound dome, while the front and side speakers in the main bar and surrounds also meet each other so seamlessly that sound effects that transition from front to back of vice versa slide by you without any sense of a gap in their sonic path.

The same seamlessness applies to sounds that pass across the soundstage from side-to-side, or even right over your head.

It’s not just the absence of gaps in the Q990H’s sound stage that’s so impressive, either. The rears also manage to tonally match the speakers in the main bar superbly, rather than sounding relatively thin or lightweight. The side-firing speakers the rears carry prevent the sense of funnelling in that you can get with less channel-rich surround sound soundbar systems, too.

The huge power and impact we’ve come to expect from Samsung’s flagship soundbars is present and correct, ensuring that the huge soundstage not only fills even large rooms, but also places effects within that soundstage with remarkable precision and confidence. It can also go suitably, cinematically loud without sounding at all strained or forced.

The system’s power and excellent channel steering helps it deliver phenomenal directness and impact too, ensuring that gunfire, explosions, crashes, punches and the like hit you with a visceral intensity, all the while ensuring that dialogue is always crisp, clean and intelligible.

The soundbar and even the rears are capable of achieving some surprisingly deep low frequencies for such compact looking items, but the subwoofer seals the home cinema deal by rumbling out some of the deepest bass I’ve ever heard from any external soundbar bass speaker.

It rolls its huge low frequency contribution out with exceptional smoothness too, and there’s no sense of it ever flattening out against any sort of low frequency ‘bottom’, even under the heaviest movie mix pressure. The dual woofer arrangement helps spread bass throughout your room so effectively, too, that it always feels non-directional, exactly as it should.

While details are crisp and clean, they never sound harsh or shrill even with the highest frequencies, and the system’s intelligence when it comes to apportioning the correct weight to every element of a movie mix is outstanding.

Samsung fixed its flagship soundbars’ previously long-running issues with sounding as good with music as they do with movies a couple of generations ago now, and the Q990H doesn’t alter that trajectory.

In pure stereo mode it combines spectacular levels of room-filling power with a genuinely refined sense of stereo playback, delivering excellent but not excessive left/right separation, a huge but coherent dynamic range (thanks in no small part to the impressive nimbleness, timing and musical awareness of that meaty subwoofer), excellent detailing without becoming forensic, and great vocal positioning and warmth. Regardless of whether the vocalist is male or female.

You might be wondering at this point where, if anywhere, the Q990H might have improved over its predecessor. There are a couple of things I noticed. First, it delivers a slightly more detailed, precise and consistently defined sense of height with Dolby Atmos overhead and height effects – connected to which, the new Sound Elevation feature is an excellent addition to the soundbar’s flexibility.

Second, the bass from the subwoofer seems to roll out even more smoothly and cleanly than it did with the Q990F, as well as adapting even better to music.

Digging hard for anything negative to say about the Samsung HW-Q990H’s performance, vocals can sometimes sound a touch clipped and sharp against the system’s otherwise impressively rounded tone.

Connected with this, sometimes a hard-edged musical sound such as a snare drum hit can sound a little too crisp – and this issue becomes more exaggerated if you use the otherwise quite effective Surround up mix option for stereo music. Aside from the previously mentioned drop to a lossy Dolby Atmos format if you want to use Samsung’s wireless Dolby Atmos delivery system, though, that really is all I’ve got in the negative column.

Should you buy it?

Samsung’s HW-Q990H doesn’t reinvent the wheel. Its improvements over its predecessor are mostly limited to an effective new Sound Elevation feature that’s especially helpful with really big TVs; slightly more height effect clarity; and smoother, rich bass delivery from its eye-catching subwoofer.
 
But any improvements at all to what was already a class-leading soundbar package are more than enough to keep Samsung on the surround sound soundbar throne.
