    Outstanding Soundbar — Nearly Perfect

    I picked up the LG SC9S and I have to say it has completely transformed my home audio experience. The sound is rich, full, and powerful — dialogue is crystal clear and the bass hits hard without being overwhelming. Dolby Atmos support is the real deal on this thing, you can genuinely feel the difference with movies and music. Pairing it with my TV was seamless and the setup took no time at all. The design is sleek and fits perfectly under my screen without being bulky. My only small gripe is that the app could be a little more intuitive, but once you get familiar with it everything works great. Overall an incredible soundbar that I would absolutely recommend to anyone serious about their home audio.

    GREAT SOUND BAR!!!....OPEN BOX WOES

    Really nice sound bar! Promptly delivered! Open box and got a really great deal! So I thought..... It is nearly impossible to get customer service on products that are ordered. . They promptly want you to return it with no option to say hey there's something missing. My purchase was missing the power cord for the soundbar, there was a cord for the subwoofer. We actually contacted the local Best Buy and they asked what was the condition of the open box. . We told him excellent and he said there should have been nothing missing but could not help with getting me the proper power cord /adapter... Suggested third party adapter per Amazon. I happen to have a smaller LG sound bar I had purchased months earlier from Best Buy and was able to power up the new sound bar... pleased with the result...So I just needed a power cord. I did not want to return the whole unit. After trying the support center route just became super frustrated and was like Hey for 50 bucks I'll buy a brand new one just not worth the aggravation. Still feel I did pretty good on the purchase. . Just aggravating process of customer service. I'll always use Best Buy for my Sound, AV, even small appliances. . Just not sure if i'll ever try to get that deal online and stick with in-store purchases. I tried to submit this via email... It seems there's no way to do such a thing so I'll go at it this way in a review....sorry...just too much automation!! -Mike On Fri, Sep 4, 2026 at 11:11 AM Best Buy Customer Reviews <BestBuyInfo@emailinfo.bestbuy.com> wrote:

    Immersive Audio Experience with Powerful Bass!

    I recently added the LG SC9S 3.1.3 Channel Soundbar to my setup, and I’m absolutely thrilled with the upgrade. The Dolby Atmos and DTS:X bring an immersive, surround-sound feel right into my living room, making movies and shows so much more engaging. The soundbar itself is sleek and fits perfectly with my entertainment center, adding a touch of modern elegance. The wireless subwoofer is a game-changer, delivering deep, powerful bass without any messy cables. You can truly feel the impact in action scenes or bass-heavy music tracks, adding a whole new layer of enjoyment. The WOW Orchestra mode is an incredible addition, providing a fuller, richer sound that makes you feel like you’re right in the middle of the action. Setup was a breeze, and it integrated seamlessly with my LG TV. If you’re looking for a sound system that combines high-quality audio, ease of setup, and a minimalist design, the LG SC9S is absolutely worth the investment. Highly recommended!

    LG Soundbar

    Love this soundbar! also love that it hooks to the TV. I am still trying to figure out the controls.. no instruction booklet came with it. No visual menu. HOWEVER, the sound is spectacular

    Its like being at the movies

    Have had this soundbar nearly a year, and it teally makes watching movies and TV shows quite immersive. Hooked it up to an LG OLED TV, easy and a relatively plug-and-play experience. Really liked that it came with a stand/mount for my existing TV since it is an LG TV. The only problem it has caused for me is its ruined watching TV anywhere else except my living room, as I find myself missing the clarity and deep bass from this soundbar. Cant afford to put another one in my bedroom but will be buying another smaller LG soundbar in my bedroom

    Amazing quality

    [This review was collected as part of a promotion.] LG SC9S SoundBar, First off, let me say that the SC9S soundbar itself has impressive overall sound quality. Movie and TV dialogue is very clear. What I find most wonderful and truly pleasing Is that that switching back and forth between TV and movies seamless… and the sound of movies is supreme. Easy to use and app was easy to navigate . If you're looking for an actual immersive surround experience, with great quality sound you found it... I highly recommend this product.....
