The premise seems simple enough. LG promises that you can set its Sound Suite speakers anywhere and Dolby’s home theater tech will make them perform well. The soundbar, subwoofer and speakers don’t have to go in prescribed locations for the best results, which means you can place them where you need to and move them as you see fit. Of course, this all hinges on the reliability of the underlying tech and LG’s ability to make individual speakers that actually sound good.
Like most premium soundbars and complete home theater setups these days, a complete Sound Suite collection is expensive. The centerpiece alone, a soundbar that most people will want in their customizable configuration, is $1,000. However, if you have a recent LG TV, or are planning to buy a 2026 model when those arrive, there’s no better option for boosting your living room entertainment experience.
The components of the LG Sound Suite
There are four different devices that make up the Sound Suite. The centerpiece is the H7 soundbar ($1,000), which is the first one that works with Dolby Atmos FlexConnect (DAFC) technology. Then there’s the 8-inch W7 subwoofer ($600) and the M5 and M7 speakers ($250 and $400). LG allows you to pick and choose between these products to build a home theater set up that suits your needs — up to four speakers and one subwoofer. The only real caveat is that you need the H7 soundbar or a recent LG TV (2025 OLED G5, C5, CS5 and QNED 9M, or an upcoming 2026 model) to serve as the primary device for Sound Suite to work. That’s because the underlying tech requires LG’s alpha 11 Gen 3 AI processor, which is inside the soundbar and the company’s newer TVs.
The H7 houses a dozen Peerless drivers comprising front, side and up-firing units. There’s also four woofers and eight passive radiators for bass and low-frequency audio. The soundbar has a pretty basic design, plain enough to sit in front of an LG OLED (or other premium TV) without being a distraction, and short enough not to block it. Both Bluetooth and Wi-Fi are available here, so AirPlay 2, Google Cast, Spotify Connect and Tidal Connect are all supported.
The W7 wireless sub has an 8-inch woofer that gets really boomy at times. It’s quite large at 16.1 x 16.3 x 7.6 inches, but you can use it standing up vertically or laying down horizontally — whichever orientation fits your needs or available space. The M5 and M7 speakers offer basically the same features, including AirPlay and Cast, and can be used either by themselves, as a stereo pair, as a four-speaker array or as rear satellite speakers with the H7 soundbar. The main difference is the M7 has two full-range drivers, one up-firing driver and a woofer while the M5 only has a tweeter, an up-firing driver and a woofer.
What is Dolby Atmos FlexConnect?
FlexConnect is a home theater audio technology that Dolby announced in 2023. It was available on TCL’s Z100 speakers last year, but LG’s Sound Suite marks the first time the feature has been available on a more robust living room product that includes a soundbar. FlexConnect allows you to position speakers anywhere in a room without sacrificing audio performance. The tech uses a TV or soundbar as the lead device to locate speakers so it can tune the sound to match their positioning. The system can also quickly adapt when you move a speaker — maybe for a party or other special occasion.
FlexConnect works as advertised, but there is one caveat that should’ve been obvious, although I didn’t anticipate it. Every time you add or remove speakers from a DAFC group, you’ll need to recalibrate the system, which includes the software playing sounds from the speakers so that the TV or soundbar can locate them and Dolby’s tech adjusts their output. It doesn’t take long, but there is audible noise from each unit in the group, so you’ll want to factor in that time — and potential annoyance for anyone else in the house.
Other Sound Suite features
Sound Suite offers some of the same features as LG’s other home theater products. Those include Night Mode, Room Calibration Pro, AI Sound Pro+ real-time audio upscaling and Clear Voice Pro+ for enhanced dialogue. For the Sound Suite, LG has also introduced Sound Follow, a feature that allows you to adjust the “sweet spot” for the system based on where you’re sitting.
Once you set your current position with a tap in the ThinQ app, Sound Follow is supposed to change the levels and tuning accordingly. I’m not entirely sure this was working on my system. Unlike my demo at CES, the seating position on the FlexConnect layout in the app was never updated. And while the UI seemed to indicate the change was made when I tapped the buttons, I couldn’t hear any difference in the audio. I asked LG for more information to ensure Sound Follow is functioning properly.
A word about setup
Like most soundbars and speakers these days, you have to use an app to get them all connected and properly set up. And like Samsung, LG makes you do that through the same app that handles all of its connected devices — including appliances. Once you unbox and plug in the Sound Suite speakers, you add them in the ThinQ app as a new home theater arrangement. The software shows you which speakers are available to use and allows you to select which ones you want in the initial Dolby Atmos FlexConnect grouping.
The app will ask you to set the distance between the soundbar and your primary seating area before running the sound optimization (tuning) process. ThinQ will display the speaker layout and you can edit the DAFC group at any time. If you move a speaker though, you’ll need to run the optimization again for the best audio performance. And if you’re using an LG TV as the lead device, all of this is sorted onscreen rather than in the app.
Overall, the process is pretty straightforward, although I encountered some pretty significant connectivity issues that were very frustrating. I review soundbars and speakers regularly, so I’m familiar with the process of using an app to connect devices to my home Wi-Fi in order to get them up and running. With the H7, it took a few days to get it connected, which meant I could only use the soundbar with the audio options available on LG C5’s menu and wasn’t able to set up a larger Sound Suite configuration. After several router and soundbar reboots, I was finally able to get the H7 to connect and become available to finish the install. I’ve never had this problem before, so perhaps LG did something different with the Wi-Fi components here.
When I was adding the M7 speakers to my DAFC setup, I had no issues connecting them to Wi-Fi initially. However, I did have trouble adding them to the FlexConnect group, which required each piece of the Sound Suite playing an audio calibration clip. Repeatedly, the ThinQ app told me there was a connection issue with one of the M7s, although eventually they all somehow got added anyway. I also had trouble removing speakers from the arrangement. Even though the app said sound was only coming from the H7 soundbar, one of the two M7 speakers was still connected and emitting sound when I didn’t want it to. For some reason, this only happened when playing music over AirPlay — TV audio over HDMI eARC always functioned as intended.
If you’re using the TV as the lead device, you do all of the setup on the screen. I found this method to be more straightforward and reliable, although it blasted the calibration sounds at a deafening volume. There is a big issue though: Once connected to the TV as a DAFC setup, the speaker settings weren’t available in either the ThinQ app or on-screen menus. This meant I was stuck in standard mode, with things like AI Sound Pro+ inaccessible. I asked LG for more info on this because it greatly impacts the overall experience.
Which configuration sounds best?
Before I get into describing the various Sound Suite configurations, I need to make an important note about the limitations for the possible setups. LG only allows a maximum of five speakers in any Sound Suite arrangement, but you can mix and match however you want. Just remember if you don’t opt for the H7 soundbar, you’ll need a compatible LG TV as the lead device for FlexConnect to work.
You can also use the M5 and M7 as standalone speakers in another room and swap them in and out of your living room or home theater setup as needed. In the multi-room scenario, Sound Suite speakers function much like a Sonos system would, and the M7 is more than capable of being a standalone music speaker with plenty of detail and decent bass. I wasn’t able to test the M5, so I can’t vouch for that one. Keep in mind that if you opt for the M5 or the M7 for your living room, you’ll need at least two of either one to use FlexConnect with your LG TV.
After testing multiple configurations of the Sound Suite, I think the combination of the H7 soundbar, W7 subwoofer and two M7s is the ideal arrangement. I’ll hedge that a bit as I prefer to disable the M7s in the rear of the room when watching live TV — especially sports — as the same audio coming from the soundbar and those speakers didn’t really enhance the experience. Plus, arena noise seemed overly echo-y and off-putting. This setup is well-suited for streaming TV shows and movies, things where Dolby Atmos, or at least LG’s spatial upscaling, is at the height of its powers.
In this setup with the H7 as the lead, you get Sound Suite in its most immersive form. I always use Netflix’s Drive to Survive as my first test of a new home theater system, and LG’s lineup handled it like a champ. You get excellent directional audio, which makes the cars sound like they’re zooming around your living room. And the in-car shots are so enveloping, it’s like you’re sitting right behind the driver. This configuration also works well for music, though I preferred to use either one of the M7 speakers or the soundbar/sub duo rather than the whole shebang.
My second favorite setup is four M7s. Once again, this configuration requires an LG TV as the lead device, but if you have that, you can definitely save some room in front of your television with separate front speakers. Unfortunately, you can’t use a subwoofer too because if you’re using a TV to power the speakers, you can only add up to four. That’s a real bummer, but the TV speakers will be used as a center channel (dialogue) boost, so it’s not a complete waste. However, this arrangement would benefit from more bass.
The four-speaker setup could be particularly beneficial for people who mount their TVs on the wall and don’t want a soundbar underneath. And, again, FlexConnect allows you to put the speakers anywhere, not necessarily flanking your TV. You also get the option of moving these smaller speakers around when you need to — something you can’t really do with a soundbar. The only sacrifice I noticed audio-wise is that two M7s in the front doesn’t offer the same overhead sensation for Atmos content as the H7’s up-firing drivers.
If you’re just using four M7 speakers for home theater duties, you’ll enjoy the immersive audio these Sound Suite speakers will provide. There’s lots of directional sounds with Atmos content, and there’s plenty of subtle detail that comes through on movies and shows. However, for live sports, this arrangement pulls commentary audio from the TV speakers and puts much of the arena/stadium noise in the rear M7s, which makes it difficult to hear the announcers at times. This is one area where the inability to adjust the audio settings really hampers the experience.
If you’re hoping to invest in something that can pull double duty for music, I prefer one or two M7s for that purpose. And while there’s decent low-end thump, streaming your favorite tunes is where you’ll notice the absence of that W7 subwoofer.
The competition
If you’re looking for alternatives to LG’s Sound Suite, you have to make some sacrifices. The only other option right now that offers Dolby Atmos FlexConnect is the TCL Z100 speaker. Obviously, you’ll need multiples of this $300 device, and you’ll probably want to add the $350 subwoofer, too. Like the LG M7, you’ll need a compatible TCL TV to serve as the lead device for FlexConnect (a QM6K, QM7K, QM8K, QM9K or X11L model). I haven’t tested these 1.1.1-channel units, so I can’t provide a direct comparison to the Sound Suite’s M5 or M7.
For those who can live without FlexConnect, Samsung’s Q990 series is consistently the best all-in-one setup you can buy. I haven’t reviewed one since 2024 because the company has been keen on shipping new models with minimal updates, which means the hardware and most of the features remain the same. The HW-Q990H will be the latest installment when it arrives later this year, with the biggest differentiator being a new dialogue boost called Sound Elevation.
While the Q990 always comes with rear speakers and a subwoofer alongside a powerful soundbar, some features will only be available if you also have a Samsung TV. One of those is Q-Symphony, which utilizes TV speakers alongside the Q990’s drivers for more detailed and immersive sound. For the entire Q990 package, you’re looking at $2,000 — $100 less than the comparable Sound Suite arrangement of the H7 soundbar, two M5 speakers and a W7 sub.
Wrap-up
There’s no denying that LG has created a powerful and immersive living room experience with its Sound Suite lineup. I also like that the company allows customers to decide what they need without sacrificing the main draw of FlexConnect. While I did experience some setup and software issues, those are things LG can iron out over time — Sound Suite is still brand new, after all. I would like to see the company offer some discounted bundles and continue to add more audio features over time to justify the hefty investment. If you’ve got a couple grand to spend, especially if you have a recent LG TV, Sound Suite will be your best option for building out a home theater setup.
