The default 4K TV speaker is two down-firing drivers in a thin enclosure on the back panel, and it sounds exactly as bad as that description suggests. Voices come from somewhere under the TV stand, music has no low end, and Atmos surround is a marketing checkbox. Some TVs have figured this out. After looking at 18 current 4K TVs with serious built-in audio systems, these seven stood out for driver layout, wattage, dialogue clarity, and Atmos handling. The lineup covers flagship picks where audio is treated as a core feature and mid-range sets that still beat a $200 soundbar.

Sony Bravia 9, Best Overall
The Bravia 9 is Sony’s flagship Mini-LED and the audio system is the reason it makes this list. A 2.2.2 channel layout uses two front-firing drivers, two built-in subwoofers, and two up-firing actuators that bounce height channels off the ceiling for real Atmos placement. Total wattage is 70W with the subwoofers doing most of the low-end work, and the result is a soundstage that feels meaningfully bigger than the panel.
Dialogue clarity is the standout. Sony’s Voice Zoom 3 processing isolates speech and pushes it forward in the mix without making music or effects feel buried. For news, drama, and dialogue-heavy streaming, the Bravia 9 needs no soundbar at all.
Trade-off: at flagship pricing this is a $2500 to $3500 TV, and the audio system is one feature among many. If audio is the only reason to buy, the mid-range picks below do most of what this set does at half the price.
Samsung S95D OLED, Best for Spatial Sound
Samsung’s Object Tracking Sound Plus uses a 4.2.2 channel layout with side-firing drivers, down-firing subwoofers, and up-firing height channels. The processing tracks audio objects on screen and pans the sound to follow them, which works surprisingly well for action sequences and sports broadcasts.
The S95D is also Samsung’s flagship OLED, so the picture is in the top tier of any TV available, and the audio matches. 70W total output, dedicated subwoofers, and an Atmos driver array that does not need a soundbar to feel immersive.
Trade-off: Samsung still does not license Dolby Vision, so HDR content from Apple TV+, Disney+, and a chunk of the Netflix library falls back to HDR10+. For Atmos audio, all major streaming platforms support it on Samsung sets.
LG G4 OLED, Best Dialogue
LG’s G4 uses the OLED panel itself as a speaker actuator, vibrating the screen to produce mid-range and treble. The result is that dialogue appears to come from the actor’s mouth on screen rather than from a driver below the panel, which is a localization improvement no conventional speaker setup can match.
Total system wattage is 60W with a built-in subwoofer for low end and side-firing drivers for stereo width. Atmos height channels are processed and reproduced through the side-firing drivers (not dedicated up-firing units), which works less well for true height effects but is still a meaningful step beyond basic stereo.
Trade-off: bass extension is shallow compared to the Sony or Samsung flagships, and the screen-actuator approach can show subtle distortion at very high volume. For normal listening levels in a normal room, it sounds excellent.
Sony Bravia 7, Best Mid-Range
Sony’s Bravia 7 brings the Acoustic Multi-Audio system down to a more reasonable price point. The setup uses front-firing drivers paired with screen actuators, a small built-in subwoofer, and 40W total output. Atmos signals are processed and downmixed to the 2.1 array rather than reproduced through dedicated height channels, but the processing is good enough that the result still feels bigger than basic stereo.
For most viewers, this is the sweet spot: clearly better than any soundbar under $200, no external hardware required, and the picture quality is also a strong mid-range Mini-LED.
Trade-off: no true height channels, so big-budget Atmos action movies do not feel as enveloping as on the flagship picks. For 90 percent of streaming and broadcast, the gap does not matter.
Samsung QN90D Mini-LED, Best for Bright Rooms
The QN90D is Samsung’s flagship Mini-LED (under the OLED line) and uses a 4.2.2 OTS+ array similar to the S95D. Six speakers across four channels plus two subwoofers and up-firing height drivers give it real Atmos capability, and the 60W total output is plenty for a normal-sized living room.
The advantage over the OLED S95D is brightness: 2000-plus nits peak HDR for sun-bright rooms where OLED struggles. Pair that with the same OTS+ audio architecture and you get a TV that handles every viewing condition.
Trade-off: same Samsung-no-Dolby-Vision issue as the S95D, and OTS+ processing can feel slightly artificial on stereo music compared to the more neutral Sony or LG tuning.
Hisense U8N, Best Value
Hisense’s U8N undercuts the flagship Sony and Samsung sets by $1500 or more and still ships with a 2.1.2 audio system tuned by Devialet. Two front-firing drivers, a built-in subwoofer, and two up-firing Atmos channels deliver real height effects in a way no $300 soundbar matches.
Total output is 50W, dialogue clarity is good, and the bass extension is the surprise of the lineup. The built-in subwoofer is small but tuned well, and music sources like Spotify Connect through the TV sound better than most owners expect.
Trade-off: build quality and platform polish trail the Sony and Samsung flagships. Google TV runs fine but feels less refined, and the remote is cheap.
TCL QM8 Mini-LED, Best Onkyo Tuning
TCL partners with Onkyo on the QM8 audio system: a 2.1.2 channel layout with two front-firing drivers, a built-in subwoofer, and two up-firing Atmos channels. Total output is 60W and the Onkyo tuning gives the sound a warmer, more music-friendly character than the Hisense.
For users who watch a lot of concerts, music videos, and broadcast sports, the Onkyo tuning is a noticeable advantage. Movie dialogue is also clear and the up-firing drivers do real work for ceiling-bounce Atmos in rooms with normal eight-foot ceilings.
Trade-off: high-vaulted ceilings or hard-surfaced rooms reduce the effectiveness of up-firing Atmos drivers on any TV in this list, the QM8 included.
How to choose
Look at the driver layout, not the wattage
Two 30-watt down-firing drivers sound worse than two 15-watt front-firing drivers with a 30-watt subwoofer. Read the spec sheet for the channel layout (2.0, 2.1, 2.1.2, 4.2.2) and the driver positions before trusting any total-wattage number.
Real Atmos needs real drivers
Atmos processing without up-firing or side-firing drivers does not produce height channels. If you want movie-theater overhead effects from a TV alone, you need a TV with actual dedicated height-channel drivers (Bravia 9, S95D, QN90D, U8N, QM8 on this list).
Dialogue clarity is the deciding feature for most viewers
Most people watch dialogue-heavy content (news, drama, talk shows) far more than action movies. A TV with strong dialogue handling (Sony’s Voice Zoom, LG’s screen actuator) is a better daily-use choice than one tuned for blockbuster bass even if the second one has more impressive specs.
Room shape matters
Up-firing Atmos drivers bounce off the ceiling and work best in rooms with flat eight-to-nine-foot ceilings of average material. Vaulted ceilings, exposed beams, or acoustically dead rooms reduce the effect. Side-firing setups (Samsung OTS, LG side drivers) are less dependent on room shape.

A TV with serious built-in audio is no longer an exotic feature, it is a real category. The Sony Bravia 9 and Samsung S95D are the right picks for buyers who want to skip the soundbar entirely, the LG G4 OLED is the dialogue-clarity champion, and the Hisense U8N is the value play that brings flagship audio architecture to a mid-range price.
Frequently asked questions
Can a TV really sound as good as a soundbar?+
A few high-end TVs come close. Sony's Acoustic Surface Audio on OLED panels turns the screen itself into a tweeter array, and the result is dialogue clarity that a $300 soundbar struggles to match. Samsung's Object Tracking Sound uses side-firing and top-firing drivers to throw audio around the room. None of these match a true 5.1 setup or a high-end soundbar with a dedicated subwoofer, but they make the soundbar feel optional rather than required.
What speaker wattage actually matters?+
Total system wattage on a TV is roughly meaningful but the driver count and layout matter more. A 60-watt TV with two front-firing 20-watt drivers and a 20-watt down-firing woofer sounds fuller than a 60-watt TV with four 15-watt drivers all pointing at the floor. Look for the driver configuration in the spec sheet, not just the wattage number. Anything with a dedicated woofer (separate from the main drivers) is a meaningful step up over basic stereo.
Does Dolby Atmos on a TV mean anything?+
It can, if the TV has actual upward-firing or side-firing drivers configured for height channels. On a TV with only down-firing stereo speakers, Dolby Atmos support is a marketing checkbox that does nothing useful. The Sony Bravia 9, Samsung S95D, and LG G4 all have real Atmos driver arrays. The Hisense U7N and TCL QM7 process the Atmos signal but cannot reproduce height cues without a soundbar.
Will a TV with great audio replace a 5.1 surround system?+
No, but it can replace a basic soundbar. A real 5.1 setup with discrete rear speakers and a subwoofer in the corner moves air in ways no flat-panel speaker array can match. A high-end TV with Atmos drivers gets you 70 to 80 percent of the way to soundbar-plus-sub performance and 30 to 40 percent of the way to a full 5.1. If you watch mostly streaming and broadcast, the built-in setup is enough. For movie nights with action films, the discrete system still wins.
What is the audio difference between OLED and Mini-LED for built-in sound?+
OLED panels can use the screen itself as a speaker because the panel is thin enough to vibrate as a driver surface. Sony calls this Acoustic Surface Audio and LG uses a similar approach on some models. The result is that dialogue appears to come from the actor's mouth on screen rather than from a speaker below the panel, which is a meaningful localization improvement. Mini-LED panels are too thick for this approach and use conventional speakers. Both can sound good; OLED has a specific advantage for dialogue placement.
