About the LG SL8YG
Elevate your TV sound
Elevate your TV sound
There are an increasing number of options for achieving three-dimensional sound at home, and most of them cost a lot more than this sound bar/subwoofer combo from LG. Plus the SL8YG supports both Atmos and DTS:X, so it's a good choice if you don't want to limit yourself to just one of these cutting-edge "object-based" surround sound formats. And it packs big, multi-speaker sound into a streamlined package, so you don't need to place a bunch of speakers around your room.
At just 2-1/4 inches tall, this bar should fit easily under most TVs. But it's wide and deep enough to include dedicated left-, center-, and right-channel speakers, along with a pair of up-firing drivers to add those immersive height effects. The remote even gives you volume control over each channel so you can dial in the sound that's right for you.
The included subwoofer is wireless so you can place it in the most convenient spot (as long as it has access to AC power). And if you want to crank that sub, the remote has you covered with independent bass level adjustment.
“OK Google, how's my commute?”
Sure — you can ask the bar's built-in Google Assistant to play your favorite Spotify® playlist or shuffle all your Pandora® stations, but it can also help you with more than music. Plan your day with weather and traffic updates. Create a shopping list, set reminders or alarms, and control connected smart home devices like lights and thermostats — all with your voice.
Not into voice control? Not a problem.
The SL8YG has Bluetooth® and Chromecast built-in, so you can wirelessly stream your favorite audio content right from your mobile device instead.
LG collaborated with renowned hi-fi pioneers Meridian Audio to equip the SL8YG with some innovative audio enhancements. They combined advanced signal processing and hardware design to expand image height and widen the soundfield so you get much richer, fuller sound than you might have thought possible from a sound bar.
Music lovers will appreciate the SL8YG's USB input and support for high-resolution audio files up to 24-bit/192kHz.

Active Soundbar Speaker: The active soundbar speaker incorporates an eight driver array that includes forward facing front left, center, and front right channels; along with upward firing Dolby Atmos enabled channels. The front left, center, and front right channels each consist of a 1" dome tweeter and 3"x1" oval woofer; while the Dolby Atmos enabled channels each consist of a 2" full-range driver. All drivers are powered by a built-in 220W amplifier (50W x 2ch to the front left & right channels, 40W x 1ch to the center channel, and 40W x 2ch to the Dolby Atmos enabled channels). The active soundbar speaker can be positioned on a flat tabletop surface using the integrated feet or the included extension feet (the extension feet add approximately 0.5" to the overall height of the soundar). The soundbar can also be wall mounted using the included wall-mount bracket (mounting screws not supplied).
Wireless Powered Subwoofer: The wireless powered subwoofer houses a front-firing 6.5" woofer powered by a built-in 220W (RMS) amplifier inside a bass reflex cabinet with a rear-firing port. Because its wireless, you can place the subwoofer almost anywhere in your room (up to 33' from the soundbar). But, it is better to place the subwoofer near the soundbar for optimum sound quality. Turn it slightly toward the center of the room to reduce the wall reflections. The wireless powered subwoofer does require an AC outlet connection.
Meridian Technology: LG partnered with Meridian Technology, pioneers of High-Resolution Audio, to combine advanced signal processing and refined hardware design, creating a soundfield with greater height, width and depth. This leading audio processing technology also provides sound quality that surpasses CDs, and allows you to enjoy stunning 24-bit/192kHz audio resolution (for HDMI & Optical), as well as 24-bit/192kHz upsampling for other audio sources (such as network and Bluetooth).
Digital Surround Sound Formats: The LG SL8YG system supports the following multichannel digital audio formats through its HDMI & optical digital inputs.
Digital Connector Audio Signal Type Audio Signal Format HDMI Bitstream
Dolby Atmos, Dolby TrueHD, Dolby Digital Plus, Dolby Digital
DTS:X, DTS HD, High Resolution, DTS HD Master Audio, DTS
PCM 2ch / 5.1ch / 7.1ch Optical Bitstream Dolby Digital, DTS PCM 2ch
3.1.2ch Surround Sound: The LG SL8YG is capable of delivering up to 3.1.2-channel surround for Dolby Atmos & DTS:X.
- Dolby Atmos: With Dolby Atmos sound comes alive from all directions, including overhead, to fill your home theater with astonishing clarity, power, detail, and depth. Rather than being constrained to channels, sounds exist as individual entities that are precisely placed and moved in three-dimensional space. A new sensation of height immerses you in the action, creating a full audio atmosphere and realistically depicting objects moving overhead. Dolby Atmos renders everything from dialogue to quiet scenes to whirlwind action with astonishing clarity, richness, detail, and depth. It all comes together in sound that excites your senses and inspires your emotions to deliver the full impact of entertainment.
- DTS:X: DTS:X is the next generation object-based, multi-dimensional audio technology from DTS. Unbound from channels, DTS:X conveys the fluid movement of sound to create an incredibly rich, realistic and immersive soundscape - in front of, behind, beside and above the audience - more accurately than ever before. DTS:X offers the ability to automatically adapt the audio to the speaker layout that best fits your space.
- To enjoy Dolby Atmos or DTS:X, you should connect your Blu-ray player's or satellite/cable box's HDMI output directly to the HDMI input on the SL8YG, because the some TV's HDMI ARC Input jacks will not support Dolby Atmos or DTS:X.
- The soundbar's optical (toslink) digital input only supports Dolby Digital (5.1ch), DTS (5.1ch), and 2ch PCM.
HDM 2.0 Input/ARC Output: The LG SL8YG soundbar speaker system is equipped with a HDMI 2.0 input and HDMI 2.0 ARC output that support up to 4K video, 4:4:4 color sub sampling, and HDCP 2.2 (does not support HDR video). The HDMI jacks also support Dolby Digital/DTS multichannel audio formats (including Dolby Atmos & DTS:X). The ARC (Audio Return Channel) function of the soundbar's HDMI output enables an HDMI ARC capable TV to send its audio stream to the HDMI output of the soundbar system.
- 4K Pass-Through: 4K pass-through allows the SL8YG to receive ultra high-definition resolution video and pass the video signal to a 4K compatible TV or display monitor. The system supports 4K@60/50Hz (4:2:0), 4K@24/25/30Hz (4:4:4). 1080p, 1080i, 720p, and 480p video signals.
- HDCP 2.2: The soundbar's HDMI input and output also support HDCP 2.2, which fully complies with the latest copyright protection standard for 4K video transmission. HDCP 2.2 is supported by the soundbar system's HDMI input and output. HDCP 2.2 is short for "High bandwidth Digital Content Protection" and is used for 4K video copyright protection for compatibility with Ultra HD Blu-ray players and 4K Satellite/Cable providers.
- 4:4:4 Color Sub sampling: The system's HDMI jacks support 4:4 color sub sampling for more vibrant and lifelike images, as well as 4:2:0 color sub sampling. With 4:4:4, luminance (brightness) and Chroma (color) are sampled at the same rate, resulting in an RGB color palette as big as the video sampling rate for a video image with more total colors, plus greater color accuracy and detail.
- ARC (Audio Return Channel): The SL8YG's HDMI ARC output connects to your TV's HDMI ARC input and allows audio from your TV to be sent through the soundbar system. Because the ARC-enabled HDMI input of some TVs will only pass 2ch PCM from devices connected to the TV via HDMI or analog, we recommend that you connect your Blu-ray/DVD player or Satellite/Cable box to the LG SL8YG directly; and then connect the SL8YG's ARC-enabled HDMI output to your TV's ARC-enabled HDMI input. This setup will give you with the best overall sound performance.
- Use a premium high-speed 18Gbps HDMI cable for the best 4K performance.
- The LG SL8YG does not support HDR video.
Optical Digital Input: In addition to HDMI connectivity, the LG SL8YG is equipped with a optical (toslink) digital input. The optical digital input supports Dolby Digital (up to 5.1ch), DTS (up to 5.1ch), and PCM (up to 2ch) audio signals.
- The digital optical output terminals of some flat-panel TVs only send an audio signal in 5.1ch when receiving Dolby Digital/DTS surround sound from the TV's built-in tuner, network connection, or connected USB device; and will output only 2ch stereo from sources connected to the TV via HDMI, or RCA (like your Blue-ray/DVD player or satellite/cable box).
