Samsung HW-Q990F Soundbar

Gaming HDMI passthrough receives positive evidence from PS5 testing, where reviewers reported no lag or video-quality drop.

1 supporting review · Limited evidence

KEF XIO

There is no dedicated HDMI passthrough for a game console, forcing gaming sources through the TV instead of directly through the soundbar.

HDMI 2.1 gaming support is praised for 4K/120-style passthrough and no lag or video-quality loss in gaming tests.

3 supporting reviews

KEF XIO

The lack of direct HDMI 2.1/4K120 passthrough is a clear drawback for high-end console setups that want to route sources through the soundbar.

Cabinet construction is mostly fine, but one reviewer reports audible creak/rattle from the subwoofer cabinet under very high-volume strain.

KEF XIO

The force-canceling cabinet and woofer design translates into very clean playback with little audible vibration, even when the bar is working hard.

Inter-speaker wireless communication is praised for retaining connections without manual input.

2 supporting reviews

KEF XIO

Wireless subwoofer integration can be stable and delay-free, but broader speaker expansion remains uneven: some options require an extra adapter and promised rear connectivity still lacks a firm timeline.

Samsung HW-Q990F Soundbar

Home theater integration is a core strength, especially with Samsung TVs/Q-Symphony, but the four-piece system can feel like clutter and Q-Symphony results vary.

10 supporting reviews

KEF XIO

The XIO is formidable as a one-box home-theater solution, but current expansion is limited by the absence of dedicated wireless surrounds. That makes it less flexible than ecosystems built around add-on rear speakers.

Wired connectivity is repeatedly described as excellent or sufficient, especially for HDMI/eARC and optical use.

4 supporting reviews

KEF XIO

Wired connectivity is easy for a basic TV setup, but the limited physical input selection becomes restrictive if you have several external sources.

Status indicators are a recurring weak spot because the dot-matrix/front display can be hard to read or tedious for adjustments.

Status feedback is a consistent usability weakness: LEDs can be hard to read, disappear from view in horizontal placement, and there is no full front display.

Remote usability is mixed: some reviewers like the simple, well-laid-out design, while others find deeper remote/display navigation tedious.

6 supporting reviews

KEF XIO

The remote is generally easy to understand and sometimes praised for its layout or backlighting, but several tests found it sluggish, limited, or not premium enough for the price.

The system’s size and weight are a tradeoff: reviewers accept the heft for performance but warn it may not fit easily under some TVs.

2 supporting reviews

KEF XIO

The XIO is heavy for a soundbar, and its roughly 10.5 kg/23 lb mass requires care when lifting or wall mounting.

3 supporting reviews

Samsung HW-Q990F Soundbar

Reviewers consistently describe the system as loud and room-filling, with enough output for large rooms; no review frames maximum volume as a major weakness.

8 supporting reviews

KEF XIO

The XIO can play extremely loud and usually stays composed while doing it, easily filling medium and larger rooms. One critical test found the sound shouty and resonant at higher levels.

The physical microphone mute is considered an important privacy/control feature.

1 supporting review · Limited evidence

KEF XIO

Privacy is mixed: the hardware microphone-disable switch is a thoughtful safeguard, but mandatory online account creation for deeper app setup drew criticism.

Detail retrieval is a major strength, with reviewers praising fine effects, quiet details, and textural information in movies and music.

6 supporting reviews

KEF XIO

Fine detail is a standout strength, from subtle debris and ambience in movies to instrument texture and low-level information in music. Complex scenes stay unusually easy to follow.

17 supporting reviews

Samsung HW-Q990F Soundbar

Dolby Atmos height and 3D effects are widely praised as convincing, well placed, and among the best reviewers have heard from soundbars.

10 supporting reviews

KEF XIO

Atmos height is often convincing and sometimes described as class-leading for a standalone bar, with effects clearly lifting above the screen. Results remain room-dependent, and a few tests found the height illusion less dramatic than rival bars or discrete speakers.

20 supporting reviews

Samsung HW-Q990F Soundbar

Most reviewers report clean performance at high levels, though one notes cabinet strain/rattle from the redesigned subwoofer when pushed very hard.

6 supporting reviews

KEF XIO

Most tests found the XIO remarkably clean at high output, with very low audible distortion or compression. One notably negative sample showed cabinet vibration, resonance, and compression when driven hard.

The smaller dual-driver subwoofer is widely praised for deep, controlled, room-filling bass, but a few reviewers note placement sensitivity, looser timing, or strain at high output.

12 supporting reviews

KEF XIO

The built-in bass is strong enough that many users may skip a subwoofer, but adding one can deepen impact, improve scale, and offload the lowest frequencies. Integration is generally easy, though cost can rise quickly.

11 supporting reviews

Samsung HW-Q990F Soundbar

Reviewers broadly praise the tonal balance, clarity, bass-to-midrange integration, and detailed highs, with only isolated complaints around music quality.

12 supporting reviews

KEF XIO

Tonal balance is usually natural, neutral-to-warm, and impressively even across the range. A few music tests exposed isolated lower-mid or bass tonal weak spots.

11 supporting reviews

Samsung HW-Q990F Soundbar

Room calibration is generally useful and effective, though several reviewers characterize the improvements as subtle or requiring small manual corrections.

10 supporting reviews

KEF XIO

Room tuning is usually quick and noticeably improves balance, spatial scale, and placement. A few tests found it confusing, limited compared with full room correction, or troublesome before firmware updates.

Cohesion is excellent in the strongest reviews, with subwoofer, bar, and surrounds described as seamless and tonally matched.

Dynamic headroom is praised for punch, scale, and powerful transient impact.

2 supporting reviews

KEF XIO

Dynamic headroom is exceptional, letting the XIO move from subtle passages to large action peaks with speed, control, and little compression.

Google integration is mixed: Google Cast support is praised as part of the wireless set, while one reviewer could not connect Google Home.

Video passthrough support is strong, with praise for 4K/120, HDR format passthrough, and gaming-friendly HDMI behavior.

4 supporting reviews

KEF XIO

HDMI passthrough is the most repeated specification complaint. A soundbar this expensive having no extra HDMI input forces all source switching through the TV and feels under-equipped beside premium rivals.

7 supporting reviews

Samsung HW-Q990F Soundbar

Value is split by price sensitivity: many reviewers say performance justifies the cost, while others say the expensive system is not clearly excellent enough.

14 supporting reviews

KEF XIO

Value is the biggest tradeoff: the XIO sounds expensive in the best sense, but it also costs enough to compete with complete surround packages. Some reviewers say the performance justifies it; others consider the premium hard to rationalize.

Stereo and music imaging are generally praised for focus, width, and staging, but one dissenting review found music performance especially weak.

8 supporting reviews

KEF XIO

Stereo imaging is unusually wide and precise for a soundbar, often placing vocals and instruments beyond the cabinet with convincing separation. Dedicated stereo speakers and a few rival bars can still produce a wider or more magical stage.

The system’s bass and spatial presentation are described as non-directional or room-filling enough to feel omnidirectional.

Low-volume performance is unusually strong, with reviewers praising quiet-detail audibility and private/low-level listening usefulness.

Surround presentation is the product’s strongest consensus area, with reviewers praising immersion, positioning, and a convincing sound bubble; one review found rear speakers weaker under stress.

13 supporting reviews

KEF XIO

For a single bar, surround simulation is frequently impressive, enveloping, and spatially convincing, with strong left-right movement and some rear illusion. Physical rear speakers still win for true behind-the-listener placement, and one critical test found the effect merely average.
