Decoding Atmos and having height channels are two claims · review
A 2.0 channel soundbar up to 100 W, with simulated height and a wall-mount kit in the box.
In brief
A hundred dollars, two channels, and no height channel at all — the Atmos here is simulated, which TCL says plainly. It is also the only listing on this shelf that tells you what is in the box. Key figures: 2.0 channels, up to 100 W · Dolby Atmos and DTS Virtual:X · AI room calibration · HDMI eARC, Bluetooth. Amazon.com had an offer at $100 on October 25, 2026.
A channel count is written front . sub . height. So 5.1.2 means five horizontal channels, one subwoofer, and two height channels.
This is 2.0. Two channels, no subwoofer, no third number at all.
Which means nothing on this bar physically plays the height layer of an Atmos track. The objects a mixer placed above the listener get rendered by processing instead — and TCL says so, in the one word that matters: the spatial audio simulates height.
Eight of the eighteen bars on this shelf have no third number: this, TCL’s own S55H (2.1), the Sony Bar 5 (3.1), the LG S40TR (4.1), the JBL Bar 500MK2 (5.1) and the 2.1 bars from Denon, Teufel and Ultimea.
The ones that do have height channels run from 3.1.1 (LG S70TY) to 11.4.6 (Nakamichi Dragon).
1 HDMI cable, 1 power cord, 1 remote with batteries, and a bonus wall-mount kit.
Thirteen other listings on this shelf do not itemize the box. On a soundbar that matters twice: an HDMI cable is required and not always included, and a wall-mount kit is a separate purchase on most bars.
Built-in AI Sonic technology adjusts audio to your unique layout and listening position.
Five of fourteen bars here calibrate. This is one of them — and the $988 Nakamichi Shockwafe 9.2.4 is not.
On a 2.0 bar the benefit is modest, because there is little to correct. It is still more than most of this shelf offers.
A better sound than the television’s own speakers. A flat panel has nowhere to put a driver, so its speakers fire down or backwards through a 10 mm gap. Any bar with forward-facing drivers beats that.
What it does not buy is bass: with no subwoofer, a slim cabinet cannot move enough air below about 100 Hz, which is where explosions and music live. TCL’s own S55H adds one for $38.
No dimensions and no weight. At least ten listings here publish neither — only Nakamichi, on each of its bars, with an “IMPORTANT SIZE NOTICE” that is the most useful thing on this shelf.
No frequency response. Only Nakamichi publishes one, at 19 Hz.
No HDMI input count — eARC is named, which means the television does the switching.

It decodes Atmos and it cannot play its height layer through a driver, and the listing is honest about the distinction: "rich spatial audio that simulates height and surround". Here is how to read any bar on this shelf. A channel count is written front.sub.height — so 5.1.2 means five horizontal channels, one subwoofer and two height channels. This is 2.0: two channels, no subwoofer, no third number at all. An Atmos track carries objects placed above the listener, and with no up-firing driver the bar renders them through psychoacoustic processing — the effect is a widened soundstage rather than sound from overhead. Eight of the eighteen bars here have no third number: this, the TCL S55H, the Sony Bar 5, the LG S40TR, the JBL Bar 500MK2 and the 2.1 bars from Denon, Teufel and Ultimea.
For the subwoofer, yes. TCL sells both on this shelf: this S45H at $99.99, 2.0 channel, up to 100 W, and the S55H at $138, 2.1 channel, up to 220 W with a wireless subwoofer. Neither has a height channel; both claim the same AI Sonic room calibration, the same Dolby Atmos and DTS Virtual:X, and the same box contents including a wall-mount kit. So the $38 buys a separate subwoofer and double the stated power — and a subwoofer is the single biggest audible change you can make to a cheap soundbar, because a slim bar physically cannot move enough air below about 100 Hz. If the choice is between height simulation and real bass, buy the bass.
It measures the room and adjusts the output, and it is more common at the bottom of this shelf than the top. TCL publishes "built-in AI Sonic technology adjusts audio to your unique layout and listening position". At least five bars here calibrate, by three different methods: TCL’s two use built-in microphones, Samsung’s QS700F uses the TV’s microphone — so it needs a compatible Samsung TV — Samsung’s Q600F uses SpaceFit, LG’s S95QR "AI Room Calibration Pro", and JBL says the bar "discovers how sound reflects off your walls and furniture". Notably the $988 Nakamichi Shockwafe 9.2.4 publishes no calibration at all. On a 2.0 bar the gain is modest, because there is little to correct.

Replacing a flat-panel TV’s own speakers for a hundred dollars — nothing more
