Decoding Atmos and having height channels are two claims · review
A 2.1 soundbar with a wireless subwoofer, up to 220 W, with simulated height.
In brief
A wireless subwoofer and double the power of its stablemate, for $9 more than the S45H on October 25, 2026 — and still no height channel. The subwoofer is the upgrade that matters; the Atmos is simulated. Key figures: 2.1 channel soundbar with a wireless subwoofer rated up to 220 W, with Dolby Atmos and DTS Virtual:X, AI Sonic auto room calibration, HDMI eARC and Bluetooth, supplied with an HDMI cable, a remote and a wall-mount kit. Amazon.com had an offer at $109 on October 25, 2026.
TCL sells two bars on this shelf:
S45H — $99.99 — 2.0 channel — up to 100 W — no subwoofer S55H — $138 — 2.1 channel — up to 220 W — wireless subwoofer
Same AI Sonic calibration. Same Dolby Atmos and DTS Virtual:X. Same box contents, wall-mount kit included.
And the physics make the choice easy. Reproducing a 50 Hz note means moving a lot of air, and a bar two or three inches deep has neither the cone area nor the enclosure volume for it. Everything below roughly 100 Hz is simply absent: the explosions, the bass line, the weight under a voice.
A separate cabinet does nothing else, which is why it does it well.
Buy the bass before the height.
Spatial audio that simulates height and surround.
The channel count reads front . sub . height, and this is 2.1 — two channels, one subwoofer, no third number.
So an Atmos object the mixer placed above you is rendered by processing rather than fired at the ceiling. The result is a wider, taller-seeming stage; it is not sound from overhead.
Eight of the eighteen bars here have no height channel: both TCLs, Sony’s Bar 5 (3.1), LG’s S40TR (4.1), JBL’s Bar 500MK2 (5.1) and the 2.1 bars from Denon, Teufel and Ultimea.
Sony puts it most plainly: Vertical Surround Engine, no in-ceiling or up-firing speakers needed.
Every power figure on this shelf is a maximum, and the word does the work: TCL 100 W and 220 W, JBL 750 W max, Nakamichi “up to 3000 watts”.
A max figure is a peak the amplifier can reach momentarily, not a level it sustains. Treat it as a size class rather than a measurement — and note that it tells you nothing about distortion at that level.
No subwoofer driver size. Four listings here do publish one: Sony 160 mm, Samsung QS700F 6.5 in, JBL 10 in, Nakamichi 8, 10 and 12 in. It is the crude proxy for how low a sub goes.
No dimensions and no weight, like at least ten listings here. Only Nakamichi publishes any — and its “IMPORTANT SIZE NOTICE” is the most useful thing on this shelf, because one of its bars is 58 inches wide.
No frequency response. Nakamichi alone publishes one: 19 Hz.

It is the best thirty-eight dollars on this shelf. The physics are simple: reproducing a 50 Hz note means moving a lot of air, and a slim bar 2 to 3 inches deep has neither the cone area nor the enclosure volume to do it. Everything below about 100 Hz — explosions, bass lines, the weight under a voice — is missing. A separate wireless subwoofer has a cabinet designed for exactly that. TCL sells both bars here: the S45H at $99.99 (2.0, up to 100 W) and this S55H at $138 (2.1, up to 220 W). Same calibration, same formats, same box contents. The difference is the subwoofer and the power, and the subwoofer is what you will actually hear.
No — it processes it, and TCL’s own wording concedes the point. The listing says "spatial audio that simulates height and surround". A channel count reads front.sub.height, and this is 2.1: two channels, one subwoofer, no third number. An Atmos mix places objects overhead, and with no up-firing driver those are rendered psychoacoustically — you get a wider, taller-seeming soundstage rather than sound from the ceiling. Eight of the eighteen bars here have no height channel: both TCLs, 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. Sony is the most candid: "Vertical Surround Engine, no in-ceiling or up-firing speakers needed."
The listing does not say, which is the gap. The subwoofer is described as "deep, punchy bass" and a "deep bass subwoofer" without a driver size, an enclosure dimension or a frequency figure. Four listings on this shelf do publish a size: Sony a "large 160mm speaker unit" (about 6.3 inches), Samsung QS700F a 6.5-inch driver "in a compact subwoofer that fits discreetly", JBL a 10-inch sub, and Nakamichi 8, 10 and 12-inch drivers across its four systems. Driver size is the crude proxy for how low a sub will go: a 6-inch cone in a small box typically gives up below 45 to 50 Hz, where a 10-inch reaches the low 30s. Only Nakamichi publishes an actual figure — 19 Hz.
