    Mostly Great

    There seems to be a hiccup that I haven't quite figured out and causes the subwoofer to cut out for a second or two. It seems like when the bass is at the the stronger range/ volume, it overexerts itself and cuts out. Would love to know what is causing that and how to resolve it, I've had that it happen before with a subwoofer that was connected via Bluetooth and the Bluetooth setting seemed to contribute. But here, I'm using an optical output and still have that issue. One thing I will say you must understand before you purchase this, is that the volume control is defaulted to a relatively low volume. In order to fix this, you will HAVE to download the app for the system. This will allow you to remove the volume limitation. You might be led to believe that there was an issue with the volume control, but it's because the main controller is in the app. It would also have been nice that this set came with stands for the speakers, that's probably why it's the price it is. In any case, it really completes our living room and makes video games and movies much more. Theatrical.

    Wish it was truly wireless

    Purchased this on a whim on sale for $349 around president’s day 2026. It is plug and play for an existing 77” B series OLED. Its primary use is for a kids gaming setup/occasional family movie night. For those purposes and at that sale price it is awesome value! Unpacking/setup was super easy, my only dislike and disappointment upon opening is that while the chosen parent rear speaker requires power the child requires a speaker wire ran to it thereby not making the system wireless. I just have the cable running across the carpet like a bum until a child decides to trip and wreck themselves over it. At some point I will have to address that annoyance because the rear speakers on level 10 make all the difference, especially at head level.

    LG 5.1.1 S70TR Soundbar

    Plug and play with new LG OLED 77 TV. ARC Sound was easy to connect. Wireless subwoofer automatically turned on. A slight half star deduction is that one of the rear speakers needs to be connected to a power source. The pair of rear speakers also need to be connected to each other. Otherwise, great sound quality for the price paid during Black Friday deals.

    At home movie theater quality sound

    Wow! Im blown away by the quality of this sound bar. Easy setup. Only con is the volume is three dots that go from green to red as you go up. Would prefer a digital display with numbers.

    It surpassed my expectations

    The setup couldn’t be any easier, just open the box, put the soundbar under my projector screen, woofer on the floor to the right of the soundbar, satélite speakers on my night stands, run the wire from the left satellite speaker to the right, plug all of them, turn the soundbar on. The satélite speaker connects automatically, connect it via Bluetooth to the projector and done. The sound is amazing!!! Tested the system with my favorite movie “Top Gun Maverick” and it was better than great!!! All the sounds I was hearing like the metal cables dragging on the aircraft carrier’s flight deck and the aircraft taking off while the music was playing made it joyful to say the least. Now I’m thinking on buying another one for my office. Concerts, sports and of course movies are more fun watching with this amazing soundbar.

  • Is this S70TR compatible with my LG Nanocell? Thank you

    Hi there, Ann. Thank you for sharing your experience with us. We understand your situation regarding the compatibility between your LG Nanocell TV and the LG S70TR Home Theater Soundbar. Based on our review of the official LG product details, the LG S70TR is designed with features such as LG TV Sound Sync that enable seamless connectivity with LG TVs. The “TV Matching” specification indicates that the soundbar is optimized for TVs 49 inches and larger. Therefore, if your LG Nanocell TV meets or exceeds that size, it is compatible with the S70TR. One troubleshooting step to ensure optimal performance is to confirm that your TV’s firmware is updated to the latest version. This will help ensure that the LG TV Sound Sync feature functions correctly and that the soundbar can fully integrate with your TV’s audio settings. https://www.lg.com/us/soundbars/lg-s70tr-home-theater-soundbar#pdp_specs If you need further assistance or detailed guidance, please send us a private message on Social Media @LGUSSupport, and our team will be more than happy to explore possible solutions with you.

  • Does this soundbar support 5.1 channels of PCM through the HDMI input? Looking to know if can play Switch or Switch 2 surround sound audio through the HDMI input.

    Hi, Jack. Thank you for your question! Yes, the LG Soundbar (S70TR) model does support 5.1 channels of PCM audio through the HDMI input. This means you can enjoy surround sound from devices like your Nintendo Switch or Switch 2 when connected via HDMI. To get the best audio experience, make sure your Switch is set to output audio in surround sound format (5.1 PCM) through the HDMI settings. You may also want to ensure that your TV or receiver is configured to pass through the 5.1 audio signal to the soundbar for full surround sound.

  • What height should rear speaker be placed at on rear wall & what angle should they be tilted at? Room is 17x12. Main seat is a 3 seat couch 8x3 in middle of rear wall. 65" lg tv with S70TR soundbar on front wall under tv. Sub is on right side of on floor.

    Hi, there. Thank you for reaching out to us regarding LG Soundbar (S70TR) model. For optimal sound performance in your room, you’ll want to position your rear speakers correctly to ensure balanced surround sound. Here's what we recommend: Ideally, the rear speakers should be placed at ear level when seated, which is around 36-40 inches from the floor. Since your main seating area is a couch in the middle of the rear wall, the speakers should be mounted or placed on stands at this height for the best sound distribution. For a more immersive surround sound experience, aim the speakers toward the seating area at a slight angle (about 45 degrees). Given your room dimensions (17x12), placing the rear speakers about 1-2 feet away from the side walls will also help avoid too much reflection, ensuring clearer sound. For the subwoofer, you're doing great with it on the floor to the side; just keep it away from corners, as this can cause a muddier bass. You can download it's owner's manual through this link: https://www.lg.com/us/support/product/lg-S70TR.AUSALLK and check for pages 2-6 for installation. Let us know if you need further assistance, and don’t hesitate to send us a private message on social media @LGUSSupport for any additional questions or troubleshooting. ^Juvy
