I tested JBL’s new Dolby Atmos soundbar, and its colossal power and expansive audio blew me away

JBL Bar 1300MK2: two-minute review

Two years after its predecessor came to town, the JBL Bar 1300MK2 has landed, aiming to deliver tons of power, awesome Dolby Atmos, and immersive surround sound. With a price of $1,699.95 / £1,299.99 / AU$2,299.95, I had very high expectations for JBL’s new flagship model. Luckily, it more than delivered.

This model stands out from the rest thanks to its detachable, battery-powered rear speakers, which can also be attached to the main bar or act as standalone Bluetooth speakers. These have 10 hours of battery life each, and can even be charged while in use, making them ideal for just about any user.

But even when it comes to the basics, this model can go toe to toe with the very best soundbars around. Dolby Atmos performance is excellent all-round, with incredibly expansive, almost three-dimensional sound on offer. This model also supports the DTS:X format, streaming over Wi-Fi and Bluetooth, as well as Auracast connectivity.

One key difference this model has over its predecessor is its incredible leap in power output. This 11.1.4 soundbar system has a maximum power output of almost 2,500W across its 29 drivers, which is almost ludicrously high. Will most users require this much might? No, but it’s there if you want to get really loud!

Beyond Atmos, you’re also going to experience crystal-clear dialogue, seismic bass, and precise treble, which makes for great listening experiences whether you’re watching movies or listening to music.

Pair that with an incredibly easy setup and a broad set of features – most of which are accessible via the JBL One app – and you’re looking at a near-perfect offering from JBL.

But the word ‘near’ is important here. There’s 4K passthrough – but only at 60Hz. That’s a shame for gamers who want to enjoy newer titles in 4K at 120fps. And even though I’m a fan of the detachable speakers, the system itself isn’t the most beautiful looking – it’s fairly standard stuff from a brand that usually likes to incorporate unique colorful elements into its designs.

Still, it’s fair to say that the JBL Bar 1300MK2 is an excellent soundbar system overall. It's costly, but pretty well priced against rivals. It sounds absolutely fantastic, and its versatile build helps it stand out in a highly competitive market. As a result, it’s more than worthy of my recommendation.

JBL Bar 1300MK2 review: price & release date

• $1,699.95 / £1,299.99 / AU$2,299.95
• Launched in September 2025

The JBL Bar 1300MK2 was launched in September 2025. It’s worth noting that in the US consumers get the JBL Bar 1300XMK2 instead, which has a slightly larger subwoofer. Typically, you’ll pay $1,699.95 / £1,299.99 / AU$2,299.95 for this bar’s services. That’s pretty similar to the launch price of the original JBL Bar 1300X.

JBL Bar 1300MK2 review: features

• Dolby Atmos and DTS:X support
• 11.1.4 configuration with detachable rear speakers
• 4K passthrough, but not at 120Hz

The JBL Bar 1300MK2 is equipped with just about everything you could want from one of the best Dolby Atmos soundbars. Of course, there’s support for expansive audio formats like Dolby Atmos and DTS:X, with up-firing speakers on board for an added sense of verticality.

On top of that, this 11.1.4 channel system makes use of MultiBeam 3.0 technology. This uses beamforming and digital processing to supply a “wide, cinema-like soundstage”, according to JBL – and I’d be inclined to agree. You get a beautifully expansive listen from JBL’s new flagship soundbar system, but I’ll speak more about that in the performance section.

Another key feature is the inclusion of AI Sound, which has featured on some Bluetooth speakers like the JBL Xtreme 4. This enables the large, dual-driver subwoofer – which can reach down to 33Hz – to deliver improved dynamics.

There are a number of settings you can play around with in the JBL One app too, which is an easy-to-use and well laid out piece of companion software. Something that instantly springs to mind is room calibration. This optimizes sound to your living space incredibly well, and even plays a sound demo after so you can experience the true three-dimensional sound of the Bar 1300MK2.

On top of that, there’s an AI-enabled dialogue enhancement setting, an ambient audio playback option, and various sound modes like Movie, Music, and Standard. There’s even a new Night mode, which only uses the two detachable wireless speakers to supply more mild audio with softer bass.

Speaking of those wireless speakers, you can even use them as standalone Bluetooth listening devices, and they can link up to other JBL models that have Auracast enabled. Of course, they won’t deliver the kind of performance you’d expect from the best Bluetooth speakers around, but the option is very nice indeed.

You get 10 hours of battery life from the wireless rear speakers, which is plenty for a day of movie watching or gaming. And whenever you’re taking a break, you can simply whack the detachable speakers back on the main bar to charge them. You can even keep them charging while in use via USB-C, so JBL really covered every base here.

Something I also appreciated about the Bar 1300MK2 was its solid array of connectivity options. These include: HDMI eARC; digital optical; Bluetooth 5.3 (though the rears use version 5.4); Wi-Fi; USB (playback on the US model only); Ethernet; and three – yes three HDMI inputs.

Here’s the thing though. Although there are three HDMI in slots, none of them offer 4K 120Hz passthrough or auto low latency mode (ALLM). That’s a little disappointing for gamers who want to enjoy titles in performance mode. Sure, you still get 4K passthrough from JBL’s new soundbar, but only at 60Hz I’m afraid.

Given that a lot of 4K TVs are restricted to only two HDMI 2.1 ports – one typically being eARC, which would be used for this soundbar – I think this ends up being a fairly important miss for gamers, especially when rivals like the Samsung HW-Q990F bring 4K 120HZ to the table.

• Features score: 4.5/5

JBL Bar 1300MK2 review: performance

• Incredible power output from 29 drivers
• Earth-shaking bass, clear dialogue, expressive highs
• Very strong Dolby Atmos and surround sound capabilities

To absolutely no surprise whatsoever, the JBL Bar 1300MK2 is a phenomenal performer in the audio department. It harnesses the power of 29 – yes, 29 – drivers, across the main bar, detachable surround speakers, and sub. All of that combines to offer a maximum power output of almost 2,500W. That’s more than double the power of its predecessor. Is it excessive? Arguably yes, but I’d rather have too much rather than too little.

And that raw power was incredibly striking when I tested the 1300MK2 out, proving to be ideal for grandiose movie soundtracks and immersive Dolby Atmos experiences. When I tuned into The Boy and the Heron, a scene with frogs and fish roaring ‘JOIN US’ at the protagonist, is meant to have imposing rumbling bass throughout. And the 1300MK2 replicated this with outstanding vigor. The regimented, deep, and moving low-frequency output was room-enveloping and grasped every last inch of my attention.

Even in spite of this, the soundbar system retains balance. The bass didn’t overwhelm dialogue, which remained clear throughout. And when the heron snapped a wooden sword in half, the high-pitched snap came through with a wonderfully natural crack. The whistle of an arrow was also expressive and bright, and I was generally really impressed by the treble performance of this soundbar.

Let’s focus on Dolby Atmos for a second, which is excellent once more. In The Mask, the frantic and cartoonish movement of the titular character was tracked with impeccable accuracy, voices sounded as if they were flowing well beyond the confines of the speakers themselves, and the overall expansiveness of the presentation was top-notch.

Over in Top Gun: Maverick, I made sure to test out the scene with a jet flying up and over the head of Ed Harris – a must-watch reference scene for soundbar testing. The verticality of this move was pretty good – definitely more believable than a lot of premium rivals. Sure, I wasn’t blown away by the sense of the jet flying above me, but this bar is using upward-firing drivers as opposed to overhead speakers, which can provide an almost tangible sense of height.

Every other aspect of audio was as good as I’d hoped. Dialogue – both with or without PureVoice active had exceptional clarity. More sudden moments in tense movie scenes hit with serious impact, showcasing the soundbar’s great handling of dynamics. And the cohesiveness of the system was great too – the rears had the perfect sense of subtlety, while the sub didn’t overshadow the clean and concise sound emerging from the main bar.

Something we appreciated about the original JBL Bar 1300 was its strong musicality. And I’m glad to report the MK2 also hits the target in this regard. Dolby Atmos music, like Dream of Arrakis by Hans Zimmer is spacious and engrossing, with ambient electronic elements and backing vocals escaping the confines of the bar itself. The heartbeat-like deep bass was dark and low-reaching too, resulting in a hypnotic listen.

Even stereo music sounds very good on the Bar 1300MK2. With Space Cowboy by Jamiroquai, spacey synths were given plenty of room to breathe, smooth percussion was expertly weighted, and bass was intent-filled once more. Vocals sounded a little recessed in my view, but that was nothing a little bit of EQ tweaking couldn’t fix.

Overall, the JBL Bar 1300MK2 is an exemplary performer in the audio department, and its raw power is truly something to behold.

• Performance score: 5/5

JBL Bar 1300MK2 review: design

• Convenient detachable surround speakers
• Strong build quality
• Overall look not spectacular, but sub is sleek

The most captivating aspect of the JBL Bar 1300MK2’s design is undoubtedly its detachable surround speakers, which are battery powered and can assume a number of roles. They can be used as part of the main bar, serve as rear channels, or just play music as standalone Bluetooth speakers.

That versatility is wonderful, and really helps this model stand out. JBL also includes slide-on end-caps for the main bar if you’ve detached the surround speakers, ensuring it looks sleek at all times.

As you’d expect, the Bar 1300MK2’s build quality is high. This is a durable, well-finished model and there’s a neat LED display that will indicate volume or input change as well as when Atmos content is being played.

In terms of looks, I’d argue that this bar is pretty much on-par with most of the competition. It’s a wide model that’s best suited to a TV sized 65-inches or more, and comes in plain black. Personally, I prefer the aesthetic of the Marshall Heston 120 and KEF XIO – models that have gone the extra mile to stand-out from the crowd with intricate details and multiple colorways.

Still, if you prefer a more understated approach, the Bar 1300MK2 will suit you just fine.

JBL describes the included sub as “compact” and even “small” on its website, but I’d say that’s a bit of a reach. Sure, it’s a very powerful unit, packing a huge 1,200W of power on its own, and you could certainly argue that it’s well-sized with that in mind. But small it is not. Having said that, it is a good-looking piece of kit, with a beautifully rounded exterior making it easier on the eye than some of the blockier models out there.

Something I really liked to see was the inclusion of L- and U-shaped brackets, as well as screws. That means that anyone hoping to wall mount the soundbar and rear speakers has the necessary tools to do so. Some rivals charge a fair amount for that privilege, so kudos to JBL!

• Design score: 4.5/5

JBL Bar 1300MK2 review: setup & usability

• Plug and play setup
• Responsive physical and digital remote
• Easy-to-use companion app with user-friendly features

Setting up the JBL Bar 1300MK2 is as easy as you’d expect. Simply hook the main bar and sub up to a power source, link the soundbar to an HDMI or digital optical cable, and you’re off. There’s no complex pairing required after this either, everything is already synced up.

There’s an included remote that you can use to adjust channel levels, bass power, volume and the like. Alternatively, you can use the digital remote on the JBL One app to control the soundbar. Both of these methods are responsive, and I never experienced pesky input delays when issuing commands.

The user-friendly app also takes you through network connection, calibration, and has a digital manual that can be referenced if needed.

More generally, this model packs in a bunch of integrated music apps for Wi-Fi streaming, an inbuilt mic for voice assistant functionality, and effective physical controls on the main bar and surround speakers. Pair that with an easy-to-read LED display and easy to detach surround speakers, and you’re getting top-tier setup and usability.

• Setup & usability score: 5/5

JBL Bar 1300MK2 review: value

• List price is undoubtedly on the premium end
• But you still get plenty of bang for your buck
• Well priced against rivals

Let’s not beat around the bush here. The JBL Bar 1300MK2 is an expensive piece of kit, with a list price of $1,699.95 (for the 1300XMK2, which has a slightly larger sub) / £1,299.99 / AU$2,299.95. In fairness, though, that’s about the same as the original Bar 1300, which launched more than two years ago now.

Also, when you consider the raw power and caliber of performance offered by the Bar 1300MK2, it competes pretty well against rival soundbar systems. The Samsung HW-Q990F, for example, is regularly selling for $1,599 / £1,499 / AU$1,599, and although it offers 4K 120Hz passthrough, it does lack the battery-powered detachable speakers and has a smaller array of speakers.

I’ve also started to see the 1300MK2 go on sale in some territories, with its price standing at AU$1,599.95 on JBL’s Australian store at the time of writing, for example. JBL is also selling the model for less in the US, and so you can expect to see sales pop up here and there in coming months and years.

Combine all of that with the bar’s impeccable performance and versatile design, and it actually ends up being a great value-for-money option, even in spite of its typically high asking price.

How I tested the JBL Bar 1300MK2

• Tested across the space of a week
• Used at our TV testing space at Future Labs
• Played 4K UHD Blu-Rays and streamed music over Wi-Fi

When testing out the JBL Bar 1300MK2, I had it hooked up to the LG C5 OLED TV via HDMI eARC. I made sure to use the detachable speakers attached to the soundbar, but usually kept them separated as rear channels. I also made sure to try them as individual Bluetooth speakers.

During my testing time, I watched and listened to a variety of content. This included a number of movies on both Netflix Premium and on 4K UHD Blu-Ray via the Panasonic DP-UB820. I also connected up my phone to the Bar 1300MK2 and listened to music via Tidal Connect, in both Dolby Atmos and stereo formats.

I also made extensive use of each listening mode: Movie; Music; Standard; and Night. Of course, I also made sure to try out the various other settings in the JBL One app too, including the voice enhancement, ambient sound, and calibration options.

On a more general level, I've tested dozens of soundbars here at TechRadar, and have tried out everything from ultra-cheap options like the Hisense HS214 through to premium alternatives like the Marshall Heston 120. My extensive experience with the Bar 1300MK2’s rivals mean that I know exactly what it takes for a soundbar to stand out, in what is ultimately a highly competitive market.
