Two M7 speakers flanking a TV in one of many LG Sound Suite arrangements (Billy Steele for Engadget)

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.
