LG Sound Suite Immersive Suite 7 Pro review
Dolby Atmos FlexConnect is well and truly here. And the LG Sound Suite Immersive Suite 7 Pro is among the first systems to make use of this technology. This sound system – composed of an LG H7 9.1.6-channel soundbar, two 2.1.1-channel LG M7 wireless speakers, and the LG W7 sub, all available separately too – is a powerful, dynamic, and expansive-sounding system. But is it capable of outdoing the home theater big boys — particularly Samsung?
Well, let’s start by tackling the Immersive Suite 7 Pro’s unique feature: its Dolby Atmos FlexConnect capabilities. This enables you to enjoy optimized sound and Atmos effects even with your speakers in non-optimal positions for traditional surround setups – the speakers map their position in the room, and adjust their output so you'll still get as close to 3D sound as they can provide. So, if your living room isn’t suited to having rear speakers to the left and right behind you, this could be a real solution.
And FlexConnect works really well in practice on the Sound Suite, helping it to stand out among the very best soundbars. I tried placing the two M7 speakers – which can work wired or wirelessly – across various spots in our TV testing space, and I was treated to clear, impactful, and balanced sound with each configuration. All you have to do is recalibrate the speakers each time you change their position, which is quick and easy to do in the LG ThinQ app.
More generally, the calibration tool provides accurate, streamlined sound, no matter where you’re seated. I had to retry this a couple of times during testing for the most accurate reading, but this wasn’t too troublesome. I did experience a couple of errors later on in my testing, but was almost certainly due to a network issue in our weird corporate network in our test rooms, so setup is likely to be straightforward if you’ve got stable home connectivity.
I want to talk about the Suite 7 Pro’s sound more generally now, because it really impressed me. Surround sound is phenomenal, and I often felt like I was truly enveloped in the movies or music I was playing. When viewing a 4K Blu-ray of 2024’s Nosferatu, I truly felt like I was at the center of the action — the movie's eerie score came through with immense power and control, high-pitched screeches pierced through the center channel and never sounded tinny or distorted, while bass was rippling yet regimented.
In addition, I was struck by the accuracy and expansiveness of the Suite 7 Pro’s Dolby Atmos performance when switching over to The Mask on 4K Blu-ray. At one point, the titular character flung through a glass door like a tornado with a truly palpable smash, and the system mapped his wild movements across the screen with tremendous precision.
Something that a lot of Dolby Atmos soundbars struggle to nail is height effects, but that’s not the case for the Suite 7 Pro. I threw on Top Gun Maverick, and during the scene where Tom Cruise flies his jet over Ed Harris, the verticality of the move was captured with commendable fidelity. The continued upward movement was traced well too, making for a highly immersive viewing experience.
One audio feature that some people may miss is support for DTS audio, meaning there’s no decoding of DTS HD or DTS:X onboard here – but that was to be expected after LG dropped DTS from its TVs in 2025. If your TV or video player supports decoding DTS, that should be fine.
But let's take it back to the fundamentals, where the Suite 7 Pro performs admirably. Dialogue is clear and direct, bass is intent-filled but doesn’t overwhelm other sounds in the frequency range, and treble is both clear and expressive.
I didn’t think music sounded perfect on this system, though, with vocals in the mid-range sometimes getting slightly obscured in the mix. Still, tunes generally sounded strong with clean bass and the Suite 7 Pro made great use of its various channels, especially with Atmos tracks. There’s AI-powered upmix mode if you want to convert a stereo audio signal into an expansive multi-channel format.
In fact, there are quite a few sound modes available, including an AI Sound setup, bass, and voice settings. Personally, I enjoyed the standard sound mode the best— it felt like the most balanced and revealing of the available options to me. But the options don’t stop there. You can adjust channel levels to suit your preferences, adjust the lighting on the rear speakers, and even activate Sound Follow mode, which centers audio on you, rather than a position in the room.
Combine all of that with Wi-Fi connectivity — which opens up hi-res 24-bit/96kHz audio and supports for the likes of Tidal Connect and Spotify Connect — and you’re looking at a feature-rich system. You’ve also got Bluetooth 5.4 connectivity at your disposal.
One thing that didn’t quite bowl me over was the Suite 7 Pro’s look. Don’t get me wrong, it’s still a nice-looking system overall and I appreciated its display, but the H7 bar itself does look a bit basic, lacking the sleek, modern look of a Sonos model or the eye-catching luxury of a bar like the Marshall Heston 120.
I did quite like the curved W7 sub, though, which can stand upright or lay flat. It's not the smallest, but that’s to be expected for a model that reaches down to 25.9Hz and packs a maximum power output of 220W. The mighty M7 wireless speakers are pretty appealing too, and their customizable downward lighting really won me over. On top of that, the included remote feels as if it's built to a very high standard, and it's highly responsive.
What I was a little disappointed by, however, was the lack of HDMI passthrough. See, when you use a soundbar system like this, you already have to sacrifice your TV's eARC port for enhanced sound. And given that many modern TVs only have two HDMI 2.1 ports, this means you can be pretty limited there – if you’ve got a couple modern consoles, say, then that may prove to be inconvenient. That’s something where the Samsung HW-Q990F outdoes the Suite 7 Pro, given that the former supports 4K 120Hz passthrough.
It would be remiss of me not to mention price, too. The H7 soundbar is priced at $999 / £899, with the W7 sub costing $599 / £599, and the M7 speakers coming in at $399 / £399 a piece. That means you’ll be fronting almost $2,400 / £2,300 for the Suite 7 Pro.
Sure, this is an almighty system, rammed with 21 speaker units, a swathe of height channels, game-changing FlexConnect technology, and excellent all-round audio. And given that we’ve tested models like the Yamaha True X Surround 90A, which comes in at $3,499 / £2,199 — a model with fewer channels and no FlexConnect — I don’t think the price is totally unwarranted.
But when you can grab a sensational system like the aforementioned Samsung Q990F for almost $1,000 / £1,000 cheaper, the Suite 7 Pro’s price could prove to be a difficult pill for some to swallow.
With that said, the LG Sound Suite Immersive Suite 7 Pro is certainly something special. It uses Dolby Atmos FlexConnect tech to great effect, its audio performance is very admirable indeed, and the speaker configuration opens up exceptionally immersive movie watching.
Yes, the lack of HDMI passthrough is a shame, and it comes at a very premium price, but if you’re looking for a system that’s designed to suit your specific needs, then this is about as good as it gets.
LG Sound Suite Immersive Suite 7 Pro review: price and release date
- Sound Suite H7 soundbar priced at $999 / £899 (about AU$1,400)
- Sound Suite W7 sub costs $599 / £599 (about AU$840)
- Sound Suite M7 speakers are $399 / £399 (about AU$560) each
- Whole system will set you back approximately $2,400 / £2,300 (about AU$3,400)
The LG Sound Suite Immersive Suite 7 Pro is pretty pricey, coming in at about $2,400 / £2,300 (around AU$3,400) in total. The individual components of this system got a price drop ahead of release, making it pretty competitive over the likes of Sonos, which also offers different parts of its system individually.
You can connect up to four of the M7 or the cheaper LG M5 speakers up to the Suite H7 soundbar, or connect speakers directly to your TV if you have a compatible model, like the LG G5 or LG C5.

Buy it if…
You want a system with Dolby Atmos FlexConnect
Is your room not best suited for a traditional sound system setup? No problem. Dolby Atmos FlexConnect means that you can place the Sound Suite’s various speakers in whatever position suits your space best, but you still get well optimized audio for mesmerizing viewing experiences.
You want top-tier performance
Not only does FlexConnect work like a dream, but Dolby Atmos is awesome on this system in general. The Sound Suite 7 Pro whips up a wide spatial impression with stellar height effects and mapping. More generally, audio quality is exceptional, with rumbling bass, clear dialogue, and expressive treble.
Don't buy it if…
You need HDMI passthrough
If you need a soundbar with HDMI passthrough, then the H7 – which sits at the core of this system – might not work for you. If you have multiple devices that use HDMI 2.1 but your TV only has a couple of these ports, then you’re going to be left feeling a little underserved.
You want a system that supports DTS audio
The Suite 7 Pro does not support DTS audio formats, which really is a shame. That means you don’t get access to DTS:X spatial audio, among other variants — something that the two rival models supply below.

Samsung HW-Q990F
It’s hard to think of a better value surround sound system than the Samsung HW-Q990F. It comes with impeccable performance, a boat-load of features, HDMI passthrough at 4K 120Hz, and a regularly discounted price tag. There’s no FlexConnect here, of course, but it’s still an excellent option. Read our full Samsung HW-Q990F review.
JBL Bar 1300MK2
The JBL Bar 1300MK2 is an almighty soundbar system with 29 drivers and a maximum power output of almost 2,500W. Its battery-powered rear speakers are versatile and compact, it supports Dolby Atmos as well as DTS formats, and it's priced pretty generously to boot. Again, no FlexConnect here, but it’s an excellent pick. Read our full JBL Bar 1300MK2 review.
How I tested the LG Sound Suite Immersive Suite 7 Pro
- Tested across the course of a week
- Used at our TV testing space at Future Labs
- Played 4K Blu-Ray, streamed movies and streamed music over Wi-Fi
I spent a week testing the LG Sound Suite Immersive Suite 7 Pro, using it alongside the LG G5 OLED TV via HDMI eARC. I tested the system using various configurations, and tried the system with the wireless speakers across many parts of our TV testing space at Future Labs.
During my testing time, I viewed and listened to a wide variety of content. I began by throwing on some movies via Netflix Premium, as well as higher-quality 4K UHD Blu-rays, which I played using the Panasonic DP-UB820. I also connected my phone up to the Suite 7 Pro and listened to some tracks via Tidal Connect, using both Dolby Atmos and stereo formats.
Of course, I made sure to exhaust the Suite 7 Pro’s various features as well. I listened using all of the different sound modes, messed around with Dolby Atmos FlexConnect, and tried out the Sound Follow feature.
More generally, I've tested a load of soundbars here at TechRadar, and have tried out everything from ultra-cheap models like the Sony HT-SF150 through to luxurious alternatives like the JBL Bar 1300MK2. My experience testing rival models means that I know exactly what it takes for a soundbar system to stand out, in what is a highly competitive market.
