About the LG QP5 Éclair

Colin M.

Big sound, tiny package

LG's new QP5 Éclair sound bar system is ultra-compact, with an elegant form factor that fits under most TVs and looks great in the process. It's a solid pick for anyone that doesn't have a ton of space for their A/V system, or is looking for sound that can easily fill up a smaller room. The Éclair is pretty special for its size too, with support for immersive multichannel formats like Dolby Atmos and DTS:X. Very few sound bars can be this small, and deliver sound this powerful.

Big sound, tiny package

LG's new QP5 Éclair sound bar system is ultra-compact, with an elegant form factor that fits under most TVs and looks great in the process. It's a solid pick for anyone that doesn't have a ton of space for their A/V system, or is looking for sound that can easily fill up a smaller room. The Éclair is pretty special for its size too, with support for immersive multichannel formats like Dolby Atmos and DTS:X. Very few sound bars can be this small, and deliver sound this powerful.

Spacious effects and clear dialogue

The sound bar has five built-in speakers driven by a 100-watt amplifier, including height channels for overhead effects. An elegant wireless subwoofer fills out the low-end, adding impactful bass to help you feel the action. The dialogue isn't lost in all the sound and fury though. A dedicated center channel keeps quiet moments clear and easy to follow.

HDMI makes it easy

The bar's HDMI connections allow 4K video passthrough with support for HDR (High Dynamic Range), including HDR10 and Dolby Vision®. That lets you maintain a high-contrast Ultra HD picture from your Blu-ray player or video game console through to your TV. The bar also supports eARC (enhanced Audio Return Channel), so it can receive uncompressed audio signals — including Dolby Atmos — from an eARC-equipped TV.

Stream your favorite music

Built-in Bluetooth lets you wirelessly stream your favorite tunes from your phone directly to the sound bar. If you want to minimize cord clutter, you can even use the sound bar's Bluetooth to receive a stereo signal from a compatible LG TV.

Enjoy high-res

If you have a collection of high-resolution music files, you can play them on this sound bar system. It handles audio files up to 24-bit/192kHz. So, if you've got quality tracks stashed on a USB drive, you can plug it right in and rock out.

Made to work together

The Éclair is designed to work seamlessly with 2021 LG TVs. You can reduce the clutter on your coffee table by controlling the sound bar with your TV remote. You can also enhance audio performance with TV Sound Mode Share, letting the bar benefit from your TV's built-in audio processing.

Product Research



Active Soundbar Speaker: The active soundbar speaker incorporates a five driver array that includes forward facing front left, center, and front right channels; along with upward firing Dolby Atmos/DTS:X enabled height channels. Each channel consists of a 2" full-range driver. A built-in 100 watt amplifier delivers 20 watts of power to each driver. This 5 driver configuration with dedicated front, center, and height channel delivers an immersive audio experience of Dolby Atmos/DTS:X soundtracks.

  • The active soundbar speaker can be positioned on a flat tabletop surface.
  • The soundbar should be centered above or below your flat-panel television.
  • Make sure there are no obstructions above the the top-firing Dolby Atmos enabled drivers.

Note: The active soundbar does not offer mounting brackets, keyhole slots, or threaded inserts for wall-mounting the speaker.

Wireless Powered Sub: The wireless powered subwoofer houses two 5.25" bi-directional woofers powered by a built-in 220W (RMS) amplifier for deep, accurate bass. The two 5.25" woofers feature a bi-directional configuration with the woofers firing on opposite ends of the enclosure. This bi-directional configuration minimizes vibration and distortion at any volume for big, clear, high-quality bass so you can enjoy impactful movie and music soundtracks. You can adjust the sub output level independent from the system volume.

  • Because it utilizes 5GHz wireless technology, you can place the subwoofer almost anywhere in your room (up to 33' from the soundbar).
  • 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.

Note: Like the active soundbar speaker, the wireless powered sub requires an AC power outlet.

Meridian Hi-Res Audio: 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 via HDMI & USB; as well as 24-bit/96kHz audio via Optical Digital.

Digital Surround Sound Formats: The LG Eclair QP5 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
Bitstream Dolby Digital, DTS
PCM 2ch

3.1.2ch Surround Sound: The LG Eclair QP5 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.


  • The soundbar's HDMI input and output support Dolby Atmos and DTS:X. Your source device must also support Dolby Atmos and DTS:X.
  • The soundbar's optical (toslink) digital input only supports Dolby Digital (5.1ch), DTS (5.1ch), and 2ch PCM.

AI Sound Pro: AI Sound Pro integrates unique audio technologies to bring your movie and music soundtracks to life for an enjoyable and entertaining experience. AI Sound Pro consists of a Sound Field Expander for a wider soundstage, Adaptive Audio for automatic sound tuning, and TV Sound More Share to integrate seamlessly with select LG TVs.

  • Sound Field Expander: AI Sound Pro lets you enjoy the same premium sound experience in a compact design. It utilizes a Sound Field Expander that stretches and widens the audio beyond the soundbar's immediate area for an immersive audio experience.
  • Adaptive Audio: AI Sound Pro uses Adaptive Audio technology to automatically adjust frequency range and sound field extension, depending on which genre of content the user is watching: news, music or cinema. Adaptive audio uses an advanced algorithm to identify voices, effects, and frequencies then optimizes the sound by genre for a more immersive experience with every scene.
  • TV Sound Mode Share: TV Sound Mode Share allows the soundbar to use your LG TV's processing power and AI Sound Pro to make everything you hear clearer and more consistent, even from different content sources. When connected to a compatible 2021-up LG TV, the soundbar automatically switches to the TV Sound Mode Share and utilizes the TV's advanced AI Sound Pro Tuning engine to deliver superior sound through the Eclair QP5 soundbar system.

Sound Modes: The LG Eclair QP5 soundbar speaker system has a number of preset soundfield modes to make listening to your movie, music, sports, and game soundtracks even more enjoyable. You can select Standard, Cinema, Music, Sports, or Game mode from the included remote.

  • Standard: Standard mode provides optimum sound for most applications, including music.
  • Cinema: Cinema mode lets you enjoy a more immersive and cinematic surround sound.
  • Game: Game mode is optimized sound for gaming.
  • Night: Night Mode lets you enjoy sound effects and hear the dialog clearly even at a low volume levels; only accessible from the LG Soundbar App (for Apple iOS 10.0+ and Android OS 5.0+).

Volume & Output Levels: The the LG Soundbar App (for Apple iOS 10.0+ and Android OS 5.0+) provides volume & output level sound adjustments, as well as audio/video synchronization for the system.

  • Sound Levels: The app offers independent channel level adjustment for the soundbar's center and height channels, as well for the wireless powered sub.
  • Auto Volume Leveler: Auto Volume Leveler automatically adjusts the volume level of the soundbar speaker system during loud and low passages, keeping the volume level constant across all programs and advertisements.
  • DRC: The Dynamic Range Compression (DRC) function allows you to compress the dynamic range of Dolby Digital and DTS sound tracks.
  • AV Sync: AV Sync can be used to help sync video to audio when connected to a TV. Video may look slower than the audio if it is connected to a digital TV. If this occurs, you can adjust the audio delay time (0-300ms) to match the video.

HDR (High Dynamic Range): HDR (High Dynamic Range) reproduces a greater dynamic range of luminosity or brightness levels, bringing greater contrast & wider color spectrum to the screen. This increased contrast reveals the subtle nuances of the image, from detailed blacks and shadows to the brightest whites and colors. The LG Eclair QP5 supports the following HDR formats - HDR10 and Dolby Vision.

  • HDR10: HDR10 is an open standard and currently the most popular HDR format on the market. It supports 10-bit color and 1,000 nits. It uses static metadata at the start of a movie to tell the receiver and your TV that the video content is encoded using HDR.
  • Dolby Vision: Dolby Vision Content has dynamic metadata that is produced during content creation, capturing the dynamic properties of each scene. This dynamic metadata is used to optimize the picture brightness curve on a frame-by-frame basis. Dolby Vision is the preferred HDR format by major Hollywood Studios

Note: Use a premium high-speed 18Gbps HDMI cable for the best HDR performance.

eARC (Enhanced Audio Retain Channel): Along with standard ARC (Audio Return Channel), the LG Eclair QP5 supports eARC (Enhanced Audio Return Channel). ARC and eARC allows audio to be sent from your compatible TV to the soundbar system through the same HDMI cable already being used to send audio and video to your television. This eliminates the need for extra cables connected to your television.

  • eARC will support uncompressed audio formats like Dolby Atmos (Dolby TrueHD), DTS:X, Dolby TrueHD, DTS-HD, DTS HD Master Audio, and 2/5.1/7.1ch PCM.
  • ARC is limited to Dolby Atmos (Dolby Digital Plus), Dolby Digital, Dolby Digital Plus, DTS, and 2/5.1/7.1ch PCM.
  • Your TV will also need to support eARC or ARC for this feature to work. Some newer TVs will support eARC, but most TVs only support ARC.
  • The ARC-enabled HDMI input on 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, Satellite/Cable box, or Gaming console to the soundbar system directly; and then connect the system's ARC-enabled HDMI output to your TV's ARC-enabled HDMI input. This setup will give you with the best overall sound performance.


HDM 2.1 Input/eARC Output: The LG Eclair QP5 soundbar speaker system is equipped with a HDMI 2.1 input and HDMI 2.1 eARC output that support up to 4K/HDR video, 4:4:4 color sub sampling, and HDCP 2.3. The HDMI jacks also support Dolby Digital/DTS multichannel audio formats (including Dolby Atmos & DTS:X). The eARC (Enhanced Audio Return Channel) function of the soundbar's HDMI output enables an HDMI eARC capable TV to send its audio stream to the HDMI output of the soundbar system.

  • 4K Pass-Through: 4K pass-through allows the Eclair QP5 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 2.3: The soundbar's HDMI input and output also support HDCP 2.3, which fully complies with the latest copyright protection standard for 4K video transmission. HDCP 2.3 is supported by the soundbar system's HDMI input and output. HDCP 2.3 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.

Note: Use a premium high-speed 18Gbps HDMI cable for the best 4K performance.

Optical Digital Input: In addition to HDMI connectivity, the LG Eclair QP5 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 optical digital input does not support Dolby Atmos or DTS:X.
  • The LG Eclair QP5 is not equipped with any analog audio inputs.

Note: 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).

Price for just the sound bar without subwoofer?
[ Michael  May 29, 2023 ]
1 answer
The LG QP5 Eclair comes with the subwoofer included Mike. It is not available for purchase separately, sadly. IF you are only planning on using the bar and not the subwoofer you can usually score a deal in our outlet section for a slight discount when available! I hope this helps.
[ Bo  May 30, 2023 ]  Staff
I am looking for a compact sound bar with Atmos as I plan to have item shipped. Best options right now seem to be â??LG Eclair QP5â?? or â??Sonos Beam 2â??. Can I get an opinion on which is better? Or if thereâ??s another alternative? Biggest sound bar is â??26 only for shipping purposes. Thanks.
