Samsung HW-QS90H review: Cinematic sound, no subwoofer required

Samsung has built an enviable reputation among the best soundbars, with its increasingly impressive Q-Series models, complete with wireless subwoofers and optional rears. For many, they’ve completely replaced separate amp-and-speakers setups.

The HW-QS90 cuts the clutter even more. It’s an all-in-one design, engineered to deliver a convincing Dolby Atmos from a single enclosure. Typically, the province of entry-level soundbars, here Samsung has packed the QS90H with high-end drivers in a 7.1.2-channel configuration, driven by top-notch processing.

Is it really possible to deliver uncompromising home cinema audio from a single slab? Let’s find out...

Price & Availability

The HW-QS90H is priced at £899 in the UK – a tag that places it firmly in premium territory. That'll drop over time, though, if you're prepared to wait.

Given that you can currently pick up 2025’s HW-Q930F, a more ambitious 9.1.4 package with wireless sub and wireless rears for just £699, this looks a tad toppy.

There again, it’s a positive steal if you compare it to Samsung’s latest HW-Q990H flagship, an 11.2.4 offering, which comes with all the trimmings, including a hefty £1,599 price tag.

The QS90H sells for $999.99 in the United States. It’s also supposedly heading for Australia, although its price is still yet to be confirmed.

This soundbar is also available in Germany, as the differently-named HW‑QS95GH (€949), where it comes with a ‘Made for Germany’ designation.

Features & What's New?

The feature attraction here has to be the space-saving, all-in-one, 7.1.2 Dolby Atmos configuration.

Samsung has managed to cram in three front firing drivers in a left / centre / right orientation, two upfiring drivers for atmospheric height effects, plus two side/wide firing drivers positioned at either end, plus four integrated woofers tasked with lower-frequency duties.

You’re well covered for audio formats too. The bar supports Dolby Atmos, DTS:X and the new Eclipsa 3D audio standard (IAMF decoding), as developed between Samsung and Google (for YouTube).

For Samsung TV owners, there’s also Q-Symphony support, a nifty wheeze that allows the soundbar to work in tandem with compatible TV speakers, effectively creating a wall of sound.

Samsung’s familiar AI suite is present and correct. Active Voice Amplifier Pro enhances dialogue clarity by reacting to ambient noise – useful if you have a noisy living room – while AI Dynamic Bass Control is a DSP (digital signal processing) mode to bolster low-end impact. There’s also Auto Volume control, which goes some way to smoothing out level jumps between sources.

Connectivity comprises two HDMI inputs (obviously one with eARC), as well as an optical digital audio input, plus Wi-Fi and Bluetooth. Unfortunately, HDMI video passthrough is limited to 60Hz, not 120Hz, which will be a bit of a negative for gamers who want to preserve high-framerate sources (they’ll have to connect consoles directly to their TV, and bitstream audio out).

Sound Quality

I was expecting the HW-QS90H to be good. But it actually sounds great.

This is a bold, expansive performer with a wide soundstage that pushes well beyond the physical confines of the 'bar itself. There’s real scale here, a sonic illusion created by that combination of forward, side and upfiring drivers – and it’s quickly evident that Samsung’s LA-based audio lab has done a great job with the tuning.

Height effects are particularly convincing. With spatial content, there’s a noticeable lift to the presentation, adding air and dimensionality. Watching Brad Pitt’s F1 on Apple TV, the roar of engines and the mechanical snarl of gear changes create a genuinely exciting sense of motion.

Clarity is another strong point. Dialogue sits cleanly in the mix, aided by the soundbar’s detailed midrange and the clever post-processing. Even in busy scenes, voices remain intelligible without sounding artificially pushed forward.

Bass performance is where the QS90H seals the deal. This is where the wheels could fall off Sonny Haye’s F1 racing car – thankfully, they don’t. The integrated woofers deliver a low-frequency response which I measured down to around 50Hz, but psycho-acoustically they sound like they drop even lower.

Sure, the bass has a slightly processed character. It’s not quite as tactile or visceral as a dedicated subwoofer might provide, but for a single chassis design it’s remarkably convincing. Rich and full, action movies land with authority, while music carries a pleasing beat.

In terms of presentation, I noticed a subtle change when the soundbar receives Dolby Atmos information compared to stereo or 5.1 channel sources. There’s maybe a touch more finesse and detail.

As for Eclipsa spatial audio, there’s not actually a great deal that I could find on YouTube to sample, but the official demo clip, with a variety of outdoor sports sequences, does play with impressive separation. The future-proofing is welcome – but we'll have to see how far Eclipsa adoption is driven yet.

There are limitations, though. Without rear speakers, there’s no genuine front-to-back movement. Audio effects don’t travel behind you in the way a full surround system would allow. The Q990H can deliver this, but you need to spend more and then position additional speakers in your room – which not everyone wants or can even accommodate.

Just after Tom Hardy stomps the two-headed lizard during the opening sequence of Mad Max Fury Road, the pursuing War Boys don't crash the soundstage from rear to the front, as originally designed, rather they parachute in from on high. I suspect for many, that’s probably an easy compromise to live with.

With music, the soundbar is less about fidelity and more about presence. The 'bar plays loud, soundstage spread wide. Stereo tracks like Shaggy’s Boombastic bounce along, while more intricate recordings reveal good spatial detail, if not audiophile subtlety. The presentation is confrontational, in a good way. As for multichannel music, K-Pop Demon Hunters (Netflix, Dolby Atmos), sounds, well, golden.

Design & Usability

Let’s not mince words. This is a big beast. If your TV is smaller than 65-inches, this 'bar is going to look silly in your lounge. Measuring over 1.3 metres and weighing close to 9kg, it’s best partnered with lots of glass and some robust furniture.

The design is sterotypically ‘Samsung soundbar’ – that’s to say, it’s a minimalist black slab wrapped in a perforated metal grille. There’s no fabric to soften the look. Functional rather than decorative, fashionistas might want to swipe left.

However, usability is fine. If you need them, on-body controls include Volume, Microphone and a Multi button, which handles power and source switching.

Most will probably rely on the supplied remote control, or the Samsung SmartThings app, which allows you to manage volume, select sound modes and adjust EQ.

The HW-QS90H can sit either flat, or on edge, depending on how you want to install it. A built-in gyroscope detects whether the bar is wall-mounted or placed on furniture, and adjusts its output accordingly.

Room calibration comes via SpaceFit, which uses onboard microphones to tailor sound to your viewing environment. You can run the system with or without SpaceFit engaged, and frankly I don’t think it makes much difference.

On the 'bar, there’s no text display, instead feedback is provided via LED indicators and voice prompts.

The included zapper is straightforward, but notably not solar-powered like some of Samsung’s similar-looking TV handsets. In the dark, it’s easily confused with a Fire TV remote. Or maybe that’s just me.

Verdict

Soundbars are easy to love, but partnering wireless subwoofers less so, particularly when floor space is at a premium. If this rings true for you, but you don’t want to compromise on spatial performance, the HW-QS90 is a compelling proposition.

It may be a single enclosure, but this soundbar offers an expansive soundstage with satisfying levels of subtlety and slam. It may be on the pricey side, but it’s definitely one to audition – and easily one of the best soundbars for Samsung TVs (65-inch+) if you don't want multiple speakers cluttering your setup.

Also Consider

If the form factor is right, but the price is wrong, take a look at the Sony HT-S2000, which is about a third of the price. It's a single box that offers 3.1 Dolby Atmos audio, powered by proprietary S-Force Pro Front Surround digital processing. Front facing X-Balanced speakers are helped by dual woofers – and you can always upgrade to wireless rears and a subwoofer at a later date.

Alternatively, take a gander at the Sonos Beam (Gen 2), which, at about half of the Samsung's price, is a popular Dolby Atmos 'bar with five internal speakers. It can be paired with other wireless Sonos speakers, which may further appeal. And it's far smaller, so a better match for those 55- and 50-inch TVs.
