JBL Bar 300 Review

The Bar 300 has onboard Dolby Atmos decoding but maps sound mixes to a 5.0 driver array with no physical up fires



Single-box 5.0-channel soundbar with Atmos processing


Near entry-level in JBL’s wide range

JBL ALMOST HAS a very handy model name/ pricing thing going on with its soundbars this season, as the top-of-the-pile Bar 1300 sells for approximately £, the step-down Bar 1000 sells for £, and so on. Admittedly, the Bar 300 reviewed here is actually £ and the Bar 2.0 Mk2 doesn’t sell for two quid, but at least it helps you navigate through what is an extensive soundbar range.

As the price tag implies, the Bar 300 is towards the bottom of the JBL ladder, although it shares many similarities with higher-priced models, not least the overall styling. This new lineup riffs on the brand’s designs of yore, with tidy but slightly nondescript dark-grey enclosures, topped by a logo and smattering of buttons. Parked under a 55in TV, the 82cm-wide, 5.6cm-high Bar 300 doesn’t draw much attention to itself.

There are seven soundbars in the new JBL stable, and with some hitting very similar price points it can be confusing; this option is priced very close to the £ Bar 2.1 Deep Bass Mk2. That comes with a subwoofer, while the Bar 300 doesn’t. But what you get instead is a 5.0-channel speaker config and Dolby Atmos processing.

This 3D sound skill isn’t native, however, with six drivers facing front and side. JBL’s MultiBeam signal processing is on hand to manage sound dispersion, coupled with an auto-calibration routine to best fit the output to your listening environment. This process is activated by a button on the bundled remote marked ‘Calibration’, whereas, on previous JBL soundbars, it was practically a hidden feature, involving a convoluted series of key presses. Finally, common sense has reigned, although some features (PureVoice tech for boosted dialogue clarity, and switching from Smart to Standard modes to kill surround processing) still require some finger-mashing on the zapper or use of the partnering JBL One app.

Another new feature of the improved remote control, however, is a button for bass level adjustment, while the One App brings more flexibility regards sound, with treble, mid, and bass EQ tweaks.

Connections are HDMI in and HDMI out/ eARC, with HDR passthrough including Dolby Vision but not HDR10+. Optical audio is provided for legacy TVs, but the USB port is, as before, service-only in the UK while supporting MP3 playback in the US. Pah.

Processing power

As a compact soundbar without an external subwoofer, the Bar 300 naturally has its limitations regards low-end reach and soundstage scale, but for the money, it can be considered a classy, enjoyable performer. Particularly impressive is how easy it is to live with, and the potency of JBL’s processing. Disengage the Smart Mode (which is on by default) and you’ll notice how much expansion and projection you’re losing.

With Michael Mann’s The Last of the Mohicans (Sky Cinema), the Bar 300 paints a nicely immersive picture, with atmospheric details, such as twittering insects at night in the forest, spread across its front-heavy soundstage. Bass delivery is equally impressive. The out-of-the-box ‘Level 3′ setting is punchy with Foley effects and adds genuine body to Trevor Jones’ A-grade musical score, and adjustments up and down are well-judged. The bar is rear-ported, though, so you’ll want to avoid sitting it directly against a wall.

There was an even greater feeling of low-end drama with the Atmos soundtracks of The Last of Us (Sky Atlantic), as the Bar 300 unleashed meaty, attacking bass blows during the fight with the clickers in Episode 2. Effects higher up the range are also pointy and distinct. Add in the sense of a fluid sound field with Atmos material (as opposed to genuine overhead immersion) and you arrive at a sound that’s inviting, one that draws you into what you’re watching. As Ellie, Joel and Tess navigate their way through Boston’s abandoned buildings, the acoustics of the locations are presented, even with some quite head-turning expansions far left and right.

JBL’s One App, which I haven’t used before, is as slick as an otter in a toboggan. It offers a clean, modern-looking interface, found the soundbar in double-quick time, and acts as a gateway to third-party streamers, including Spotify. Best of all is the touch control of its three-band EQ, which rewards instantaneous changes to the bar’s output. This came in handy to add a bit more brightness to the overall sound, reducing a slightly chesty delivery of voices.

Compact conjurer

Overall, the Bar 300 is a rock-solid, easy-to-accommodate soundbar that extracts a lot from a seemingly simple spec. It’s well-connected, smart where it needs to be, and conjures soundscapes bigger than you’d imagine. It should be auditioned if you have a TV in need of a serious sonic boost
