Decoding Atmos and having height channels are two claims · review
A 3.1.1 soundbar with a wireless subwoofer and an up-firing center channel for dialogue.
In brief
Three channels, one height channel, and an up-firing center — which is an odd place to put dialogue, since a voice should come from the screen rather than the ceiling. Key figures: 3.1.1 channel QNED TV matching soundbar with a wireless subwoofer, Dolby Atmos with an industry-exclusive up-firing center channel for dialogue clarity, WOW Orchestra and WOW Interface for LG televisions, Smart Up-Mixer and optional 2.0 channel wireless rear speakers. Amazon.com had an offer at $299 on October 25, 2026.
“an industry exclusive up-firing center channel that focuses on dialogue clarity”
Those two ideas pull against each other.
A center channel exists for one reason: so that voices appear to come from the mouths on the screen. In a cinema the center speaker sits behind the screen for exactly that.
An up-firing driver works by bouncing sound off the ceiling so it arrives from above. That is how every Atmos height effect on this shelf is produced.
Using one for dialogue sends the voice to you via the ceiling — the opposite of anchoring it to the picture.
There may be a case for it: a reflected path can add perceived clarity in a reverberant room. The listing does not make it.
A channel count reads front . sub . height. So: three front channels, one subwoofer, one height channel.
That one height channel is a genuine step up from the five bars on this shelf with no third number at all — both TCLs, LG’s own S40TR, the Sony Bar 5 and the JBL Bar 500MK2, all of which can only simulate.
And it is a long way from a mix. An Atmos film places objects overhead to the left, overhead to the right, and overhead behind. One height driver collapses all of them into a single point above the television.
For comparison: Samsung 3.1.2 (two height), LG’s own S95QR 9.1.5 (five), Nakamichi Dragon 11.4.6 (six).
Most bars under $300 on this shelf are 2.0 or 2.1 — a stereo pair. Three front channels means dialogue gets its own driver, physically centered, instead of being summed into both speakers and left to float.
That is the single clearest improvement in television sound, and it is why movie theaters have a center channel at all.
2.0 Ch rear surround speakers… have wireless conn[ectivity]. Sold separately.
Which makes this a system rather than a product — you can add rears later. Note that LG’s own S40TR at $199.99 includes rears in the box, with no height channel; this is $289.99 with a height channel and no rears.
WOW Orchestra, WOW Interface, and the QNED styling match. All three need a compatible LG television.
Six of fourteen bars here carry that condition: three LGs, two Samsungs, one Sony. On another brand of TV the bar works and the headline features do not switch on.
No power figure. No dimensions, like ten listings here. No HDMI input count, so the television does the switching. No room calibration, which LG’s own S95QR publishes as “AI Room Calibration Pro”.
8,700 g is published — the second heaviest LG here.

Because dialogue should come from the picture, and this one is aimed at the ceiling. LG publishes "an industry exclusive up-firing center channel that focuses on dialogue clarity" — and the two halves of that sentence pull against each other. A center channel exists so that voices appear to come from the mouths on screen, which is why in a cinema the center speaker sits behind the screen itself. An up-firing driver works by bouncing sound off the ceiling so it arrives from above; that is exactly how Atmos height effects are produced. Using it for dialogue means the voice reaches you via the ceiling, which is the opposite of locking it to the screen. The claim may well be that a reflected path adds clarity in a reverberant room — the listing does not explain it.
It is the minimum that plays height at all, and that is a real line. A channel count reads front.sub.height, so 3.1.1 gives three front channels, a subwoofer and one height channel. Five bars on this shelf have no third number — both TCLs, the Sony Bar 5, LG’s own S40TR and the JBL Bar 500MK2 — so they can only simulate height. One real height channel is a step up from simulation and a long way from a mix: an Atmos film places objects left, right and overhead, and a single height driver collapses all of them to one point. The bars here with more: Samsung 3.1.2 (two), LG S95QR 9.1.5 (five), Nakamichi up to 11.4.6 (six).
Three of this bar’s named features, if your television is another brand. WOW Orchestra makes the TV’s own speakers play alongside the soundbar rather than muting — which genuinely widens the front stage. WOW Interface puts both on one remote. And the bar is sold as "especially ideal for your LG QNED", meaning the finish and height are matched. All three need a compatible LG set. At least six of the eighteen bars here are like this: the three LGs, Samsung’s Q-Symphony, Samsung’s QS700F (which calibrates using the TV’s microphone, so without a Samsung TV it cannot calibrate at all), and Sony’s Voice Zoom 3. On a different TV the bar still works — it just stops being the bar you paid for.
