The LG S77S 3.1.3 is a 400W soundbar with Dolby Atmos decode and WOW Orchestra. Merely put – marry it with a appropriate LG TV, and it additionally makes use of the TV audio system for a greater sound expertise.
What’s the LG S77S soundbar?
It’s a 3.1.3, all-in-one soundbar comprising 9 audio system plus a Sub-woofer.
- Left front-firing 30W 6 Ω, 10% THD plus left front-firing tweeter (it is a easy frequency cross-over tweeter to bolster excessive treble)
- Proper entrance firing 30W plus proper front-firing tweeter – ditto
- Centre front-firing 30W
- Left up-firing 30W
- Centre up-firing 30W
- Proper up-firing 30W
- Sub-woofer 7” 220W 3 Ω, 10% THD declare 35-160Hz
Don’t let the 400W complete RMS energy idiot you. That’s over ten audio system with over half within the sub-woofer. It gained’t be any louder than any typical soundbar.
It may well decode Dolby Atmos’s (DA) 128 sound channel metadata and downmix to the soundbar’s functionality. DA doesn’t but recognise the centre up-firing channel, so it’s seen as 3.1.2. The centre up-firing ensures clear voice comes from the display, and it does that nicely.
No 3.1.2 all-in-one soundbar can produce a Dolby Atmos sound expertise.
They lack any side-firing surrounds (or it could be 5.1.2), devoted rear surrounds (7.1.2), or up-firing encompass audio system (7.1.4). We use the time period ‘digital’ to explain all-in-one soundbars as they depend on psychoacoustics to bounce pontificate adjoining partitions and ceilings to present a restricted, often very front-centric spatial impact.

WOW Orchestra appropriate
WOW Orchestra makes use of appropriate LG TV audio system to fill out the sound signature and widen the sound stage. No, it doesn’t make a 3.1.3 soundbar 5.1.3 or 7.1.3 (as some retail salespersons will let you know).
The extra impact depends upon the TV’s speaker setup. For instance, the LG C3 OLED Evo at 2.2 (down-firing) and the LG G3 OLED Evo at 4.2 (down and side-firing) have totally different sound outcomes. The C3 smooths out the frequency response, and the G3 does that and barely widens the sound stage.
All LG soundbars are TV model agnostic – they’ll work very nicely on HDMI ARC/eARC and Optical In.

We use Fail (under expectations), Move (meets expectations) and Exceed (surpasses expectations or is the category chief) towards lots of the gadgets under. We sometimes give a Move(ready) ranking that’s not so good as it must be and a Move ‘+’ ranking to indicate it’s good however doesn’t fairly make it to Exceed. You’ll be able to click on on most photographs for an enlargement.
First Impression: Move+
The LG S77S has properly rounded strains and perforated black metallic speaker grills. The soundbar is sort of svelte at 890 (D) x 126 (W) x 615mm (H) x 3.6kg. The subwoofer has a passive entrance port that basically pumps the air to assist low-bass. It’s 195 (D) x 361 (H) x 280 mm (W) x 5.7kg.

These might be On (White, Orange, Blue, Purple, Inexperienced, Yellow, Purple), Off or Blinking. The issue is that there are nicely over 40,000 permutations😒so hold the guide helpful.
Distant – seems to be easy, however it’s complicated. Move
Ditto. The distant has an Up/Down/Left/Proper arrow ring and an OK button (which is tough to make use of if in case you have lengthy fingernails).
It deceptively merely seems to be cover a collection of button presses and arrow instructions. Ditto for the guide.
The LG TV distant (and most manufacturers) can management quantity and energy if linked to HDMI eARC/ARC.
App – Move+
The LG Soundbar App makes setup simpler as you don’t have to look at these damned LEDs

Lacking
Wi-Fi, which implies no multi-room speaker or voice assistant help.
Energy – Move+
As much as 55W in full Dolby Atmos however averages round 20W for FTA and SDR TV.
Sound high quality. Move+
Fairly good. It reaches 85dB, however you have to again off to <80dB decibels to regulate harmonic distortion. The low- bass actually pumps from 30Hz – a stiff wind comes out of the entrance passive port! You could must again this off barely for SDR viewing.
For probably the most half, its sound stage approximates the TV.
How does it sound – Move+
If in case you have a WOW TV (examined on LG QNED86), then the gold line bass builds solidly from 30Hz to 70Hz, the place the frequency flattens (good) to 7kHz, dips barely to keep away from treble harshness and is flat then to 20kHz.The TV audio system don’t have an effect on bass however assist easy out a number of the uneven mid-and-late-mid and treble, making for very rather more nice TV listening.
If you happen to simply have an ordinary HDMI TV, it’s the identical for bass, however there is no such thing as a smoothing a number of the uneven mid-and-late-mid and treble. It’s not disagreeable, however a educated ear can hear the frequency clipping.
Dolby Atmos and DTS:X – simply satisfactory
Keep in mind that that is an all-in-one soundbar with no side-firing encompass audio system, so it’s fairly front-centric. It depends on psychoacoustics (bouncing) for 3D Peak results however doesn’t have encompass results (or it could be 5.1.3).
What it does fairly nicely is sound phasing to simulate left/proper motion.
CyberShack’s view – The LG S77S is a 3.1.3 soundbar that improves clear voice, however it’s not actually a Dolby Atmos champion.
In comparison with the QNED86 2.2 speaker setup, this was heavenly. It has a far clearer voice, extra quantity, and an excellent sound stage. Whereas we can not advocate it for Dolby Atmos, it’s a good soundbar to enhance TV sound.
LG S77S competitors
View this in two methods.
First, If in case you have a WOW-compatible LG TV, the competitors is different LG WOW soundbars. If you would like higher Dolby Atmos results, it’s the S95QR (my desire) or S90/S80QY with the non-compulsory rear audio system. You’ll be able to’t beat the centre up-firing speaker for clear voice both.
Second, in case you pay $999 and need higher Dolby Atmos, the JBL Bar 800 5.1.2 True Dolby Atmos with devoted rear audio system is great. Learn JBL 2023 soundbar vary – 5 new Bar fashions with Dolby Atmos. TCL has a $995 X937U 7.1.2 True Dolby Atmos (not reviewed, however must be good).
LG S77S 3.1.3 scores 79/100
- Options: 85 – WOW appropriate, DA decode to three.1.2 (front-centric), and clear voice centre up-firing speaker.
- Worth: 70 – Except you want WOW compatibility, there are higher true Dolby Atmos soundbars out there.
- Efficiency: 80 – first rate sound signature, particularly with a WOW connection.
- Ease of Use: 75 – The LEDs drove me loopy. The distant was not a lot simpler. The App was simple sufficient to make use of. There isn’t any room calibration, which we predict is important for DA soundbars.
- Design: 85 – good clear svelte strains.
