About the LG SP7Y

Boost your TV sound

The LG SP7Y gives you an easy way to pump up your TV sound. This bar has five built-in speakers driven by a 220-watt amplifier. Front and side-firing channels deliver a wide, detailed soundstage, while the subwoofer helps you feel the action onscreen with hard-hitting bass. The dialogue isn't lost in all the sound and fury though. A dedicated center channel keeps quiet moments clear and easy to follow.

The dialogue isn't lost in all the sound and fury though. A dedicated center channel keeps quiet moments clear and easy to follow.

Virtual 3D audio

The SP7Y generates surprisingly big sound. DTS Virtual:X uses advanced audio processing to simulate height and surround effects. Built-in Meridian Technology further expands the soundfield, making it both wider and deeper. These combine to make the action feel like it's coming from all around you.

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/96kHz. 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 SP7Y 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. 

Connect with Bluetooth

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

A wireless sub brings the bass

The included powered subwoofer is wireless, giving you additional flexibility. (As long as the sub has gets AC power, you're good to go.) You can also add LG's optional SPK8-S wireless speakers, which expand your home theater system with wraparound effects for true surround sound.

Each channel consists of a full-range driver with each Front and Surround channel receiving 45 watts of power and the center channel receiving 40 watts of power from a built-in 220 watt amplifier.

Wireless Powered Subwoofer: The included wireless powered subwoofer houses a front-firing 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). The wireless powered subwoofer does require an AC power outlet connection.

DTS Virtual:X: DTS Virtual:X allows the LG SP7Y's soundbar and subwoofer to deliver an immersive home theater experience with life-like sound above, beside, and behind you. Sound appears to virtually emerge from all around you, without the need for a multi-speaker setup. You’ll recognize richer bass, notice clearer dialog, and be amazed how it transforms your TV experience into an immersive three-dimensional experience when watching movies, listening to music and playing games. Designed to perform in any room regardless of size, layout, or acoustics, DTS Virtual:X is a flexible solution for any room configuration.

Note: The LG SP7Y does not support native Dolby Atmos and DTS Virtual:X audio soundtracks.

AI Sound Pro + TV Sound Mode Share: LG AI Sound Pro is an artificial intelligence technology that optimizes your listening experience. AI Sound Pro automatically and intelligently analyzes source content in real-time to enhance sound quality. It automatically adjust sound levels (including Bass & Treble) based on the content you are watching and listening. From powerful action to dramatic dialog, you'll hear your entertainment with crystal-clear, detailed audio. 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 SP7Y soundbar system.

Meridian Hi-Res Audio: LG partnered with Meridian Technology, pioneers of High-Resolution Audio, and employed a 24-bit/96kHz DAC (digital-to-analog converter) inside the SP7Y to produce high resolution audio that sounds closer to the real thing. Support of higher sampling rates and bit depth provide sound quality that surpasses CDs. You'll enjoy stunning 24-bit/96kHz audio resolution that is closer to the original sound.

Sound Modes: The LG SP7Y 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. Night mode must be accessed from the the LG Soundbar App (for Apple iOS 10.0+ and Android OS 5.0+).

  • Standard: Standard mode provides optimum sound for most applications.
  • Cinema: Cinema mode lets you enjoy a more immersive and cinematic surround sound.
  • Music: Music mode lets you enjoy better sound from music sources.
  • Sports: Sports mode creates a realistic sound like in a stadium.
  • Game: Game mode is optimized sound for gaming.
  • Night: Night mode reduces the general sound volume, but raises the volume of soft and delicate sounds. This is useful when enjoying music or a movie late at night.

Sound Enhancments: The LG SP7Y offers a variety of Sound Enhancements to improve bass, treble, vocals/dialog, and overall tuning. Clear Voice & Bass Blast+ can be accessed from the included remote control. Sound Tuning and DRC must be accessed through the the LG Soundbar App (for Apple iOS 10.0+ and Android OS 5.0+).

  • Sound Tuning: You can adjust the system's overall bass & treble; as well independent channel level for the center, side (surround), subwoofer, and optional rear speakers.
  • Clear Voice: Clear Voice makes vocals and dialog sound clearer; improving the quality of voice sound.
  • Bass Blast+: Bass Blast+ reinforces the bass for a more powerful sound.
  • DRC: The Dynamic Range Compression (DRC) function allows you to compress the dynamic range of Dolby Digital and DTS sound tracks.

Wireless Surround Ready: The SP7Y soundbar system has been designed to integrate with LG's SPK8-S optional wireless surround speakers (sold separately), adding dedicated rear channels with wireless convenience for 5.1ch surround sound. The SPK8-S includes an amplifier/receiver unit and pair of speakers that link wirelessly to the LG soundbar.

Note: The LG Wireless Surround Sound Kit (SPK8-S) will require and AC power outlet connection and speaker wire connection. The kit's wireless receiver/amplifier receives its audio signal wirelessly from a compatible LG soundbar speaker. The rear surround speakers connect to the wireless receiver/amplifier using speaker wire. The wireless receiver/amplifier also requires connection to an AC power outlet.

Mounting & Placement Options: The LG SP7Y offers flexible mounting and placement options for its active soundbar speaker and wireless powered subwoofer.

  • Soundbar: The active soundbar speaker can be positioned on a flat tabletop surface. The soundbar can also be wall mounted using the included wall-mount brackets (mounting screws not supplied). The soundbar should be centered above or below your flat-panel television.
  • Subwoofer: 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.


HDM In/Out: The LG SP7Y soundbar speaker system is equipped with a HDMI 1.4 input and HDMI 1.4 ARC output that support 480p, 720p, 1080i, and 1080p video. The HDMI jacks also support Dolby Digital/DTS multichannel audio formats. The ARC (Audio Return Channel) function of the soundbar's HDMI output enables an HDMI capable TV to send its audio stream to the HDMI output of the soundbar system.

  • Because some televisions, the ARC-enabled HDMI input 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 SK6Y directly; and then connect the SP7Y's ARC-enabled HDMI output to your TV's ARC-enabled HDMI input. This setup will give you with the best overall sound performance.

Basic control (such as Play/Pause and Previous/Next Track) can be done from the included IR remote. Advanced music browsing and song/artist/album display will still need to be done through your Bluetooth source device (not the soundbar).
  • Wireless TV Connection: You can even setup your Bluetooth-enabled TV to stream its audio wirelessly to the LG SP7Y soundbar speaker system. When connected to a Bluetooth-enabled TV, the LG SP7Y only decodes 2ch audio. Dolby Digital, DTS, and other multichannel audio formats are not supported via Bluetooth. During a wireless Bluetooth connection, you can use the TV's remote or the soundbar's remote to raise and lower the volume.
