Sony Bravia Theatre Trio Review: Wide Front, Shy Surround

The Sony Bravia Theatre Trio is a wireless home cinema system that reworks the traditional soundbar into a set of separate elements. It pairs a compact central unit with two front speakers, each carrying a driver aimed at the ceiling. This 3.0.2 configuration, compatible with Dolby Atmos and DTS, sets out to deliver a wider soundstage, more precise placement of effects and stronger immersion, while keeping clutter around the television under control.

To build a genuine bubble of sound, the system leans on Sony's 360 Spatial Sound Mapping technology, which generates a number of virtual speakers, and on Voice Zoom 3 to improve dialogue clarity. Acoustic calibration is carried out using an external microphone and the Bravia Connect app. Compatible with Wi-Fi 6, AirPlay 2, Spotify Connect and Bluetooth, the system can also be extended with rear speakers and subwoofers to build an installation running up to 5.2.4 channels. The Trio has been available since May 2026, and the system assessed here ran firmware 2.009 on the side speakers and 1.410 on the bar, with version 3.9.1 of the Bravia Connect app.

Sitting somewhere between Sony's Bravia Theatre Quad and a conventional soundbar, the Bravia Theatre Trio consists of three elements: a mini soundbar to place under the television, and two speakers to position either side of the screen.

The central unit takes the form of a compact bar just 59 cm wide and 6.4 cm high, and slips easily beneath a TV. Only its depth of 16.5 cm might cause a problem on the narrowest furniture, or in front of televisions with a large central foot. The side speakers are cylindrical, 33.7 cm high and 16 cm in diameter, with one face flattened to make wall mounting easier.

The speakers, like the central bar, use well-made plastic shells. The fabric covering them is particularly thin, however, and feels rather fragile as well as easy to mark.

This three-piece configuration is fairly easy to install, but it does require enough room for the side speakers and, above all, three mains sockets. Everything needed for wall mounting is supplied, along with an HDMI cable and a calibration microphone.

As on its Bravia Theatre Bar 9 and Bar 8 soundbars, Sony equips this system with distinctly thin physical connectivity, reduced to one HDMI eARC port and one HDMI input. The Bravia Theatre Trio therefore does without an optical input, without analogue mini-jack and RCA inputs, and without a USB port for playing files from a memory stick. Nor does it have the subwoofer output found on the Bravia Theatre Bar 9. There is at least the consolation of an HDMI input compatible with 4K/120 Hz, VRR and ALLM streams, which should satisfy gamers.

On the wireless side there is a Bluetooth 6.0 chip supporting the LDAC codec, with latency measured at 276 ms. The system also carries a Wi-Fi chip and supports AirPlay and Spotify Connect. Both of those protocols produced occasional unexpected dropouts, most likely down to a lack of connection stability. The Bravia Theatre Trio is compatible with neither Google Cast nor Alexa Cast, which complicates matters for owners of Android handsets.

Once the three speakers are plugged in, the Bravia Connect app is required to configure the system. Despite the obligation to sign in to a Sony account, getting started proves quick and is effectively guided by a well-designed visual tutorial.

The app then presents a main screen gathering the most important settings: a player for changing source and viewing the incoming stream, three buttons for activating the different sound modes, and a bass level control. Reaching anything more means venturing into the Settings tab, which assembles a mass of parameters whose usefulness is not always obvious.

The remote is similar to those supplied with the Bravia Theatre Quad and the Bravia Theatre Bar 9. Easy to handle and intuitive, it unfortunately has no buttons for adjusting the levels of individual channels, nor for moving between tracks in a playlist. The bar itself carries only a single button, dedicated to power.

The bar's visual interface amounts to two simple indicator lights. The first shows the selected source through its colour, while the second flashes when a key on the remote is pressed. It is therefore impossible to check the volume level or the active listening mode without going through the app. The indicators are also either permanently lit or entirely disabled from the app settings; they do not switch themselves off after a few seconds.

As noted above, the Bravia Theatre Trio comprises three elements. The two side speakers use a two-way architecture with a tweeter and a woofer on the front face. They also have a front port intended to reinforce the bass, plus a driver angled towards the ceiling to reproduce Atmos effects. The central unit, in the shape of a soundbar, is responsible only for the centre channel, which it handles with three drivers. That gives nine transducers in total for a 3.0.2 presentation.

Once the system is installed and initial configuration is finished, the app offers to calibrate it using the supplied USB-C microphone. The speakers first emit a series of test signals so they can locate one another in the room. The system has indeed been designed to allow a degree of flexibility in where the various elements sit, though keeping the speakers on the same plane is advisable so that the soundstage holds together. They then emit a second signal in order to adapt their output to the acoustics of the room.

Next comes the choice of sound mode. For music listening it is strongly worth disabling Sound Field mode in order to remove the various artificial treatments. The system then switches to stereo and only the two side speakers come into play.

With calibration done and the right sound mode selected, the system is ready to use. The Bravia Theatre Trio delivers a slightly unbalanced result, weighted largely towards the lower midrange and the treble. It unfortunately lacks extension in the low frequencies, and also a little presence in the upper midrange.

That lack of foundation is not really a problem when listening to music, and the speakers offer surprising depth given their size. It is with films that the deficit of impact makes itself felt. The dip in the upper midrange is the more troublesome of the two: the result sounds slightly veiled and muffled, which particularly affects voices, not always perfectly intelligible nor sufficiently brought forward.

The slight lift in the treble does bring a pleasant sense of air, but the lack of precision can make the result somewhat aggressive. Cymbals occasionally sound brittle, while a degree of hiss and sibilance appears on certain instruments and high voices. On distortion, by contrast, the system is faultless.

Where the Trio scores is soundstage coherence, which is far better than most soundbars manage, thanks precisely to the presence of two separate speakers. Instruments detach properly from one another, and that is one of its principal strengths.

Since the Bravia Theatre Trio is a little shy in the bass, adding an external subwoofer can make sense. Sony highlights two compatible models for the purpose: the Bravia Theatre Sub 8 and the imposing Bravia Theatre Sub 9.

The latter is a monster in every respect. Physically substantial at 40 cm along each side, it delivers phenomenal power that is completely disproportionate for a listening room of roughly 30 m2; its level had to be cut by four steps to avoid being thoroughly deafened. Its output is such that a slight lack of coherence with the rest of the system also became apparent, with the subwoofer tending to take up too much room in the presentation.

The Bravia Theatre Sub 8 is amply sufficient. More discreet, at around half the depth of the Sub 9, it delivers bass that is ample and deep enough to put the listener at the heart of the action. Its extension is certainly not as abyssal as the Sub 9's, but there was far less need to reduce its level and no real coherence problem with the Trio.

The unusual configuration of the Bravia Theatre Trio brings several advantages over a more traditional soundbar, along with a few drawbacks. The front stage is first of all particularly successful: it has real breadth, with effects that wrap around the television effectively. Unfortunately, in the absence of side-firing drivers, the soundstage stops at the speakers. Surround effects remain very timid, close to inaudible, even after calibration.

To enjoy the spectacle promised by Dolby Atmos and DTS, Sony requires Sound Field mode to be switched on. Without it, the incoming stream stays confined to a 7.1 presentation. Bringing the vertical drivers into play does reinforce the sense of immersion, but Sony's algorithms harm the naturalness of the result, which suffers from unflattering reverberation. The choice is therefore between natural and spectacular, and it is quickly made, particularly as the vertical effects are not all that impressive in the first place.

The Bravia Theatre Trio does not, then, differ fundamentally from a classic home cinema installation built on two stereo speakers, other than in having a centre channel. That channel does grant more latitude over listening position, notably by comparison with the Sony Bravia Theatre Quad.

Less spectacular than a high-end soundbar, the Bravia Theatre Trio finds its purpose above all in a room whose side walls are a long way apart. In that kind of environment, a soundbar fitted with side-firing drivers cannot use the walls to reflect effects back towards the listening position.

The Bravia Theatre Trio becomes far more interesting once a pair of rear speakers is added, in this case Bravia Theatre Rear 9 units. The system then manages to create a particularly immersive bubble of sound, spectacular enough to make one forget, at least in part, the lack of naturalness of Sound Field mode.

In that configuration, calibrating the system makes complete sense. Without it, the bubble lacks homogeneity and the transitions between the various speakers stay rather blurred. Once calibration is done, effects swirl around the listening position and the handovers between speakers become far more natural, even if a slight dip remains perceptible between front and rear. Add a subwoofer to that and the result is an excellent home cinema system.

The Bravia Theatre Trio occupies an awkward position. It sits well above most high-end soundbars in the range while shipping without either a subwoofer or rear speakers.

The Samsung HW-Q990H, positioned considerably below the Trio on its own, uses an 11.1.4 channel architecture that produces a far more enveloping soundstage, with precise side and rear effects and bass of an altogether deeper and more spectacular kind. The Sennheiser Ambeo Soundbar Max outclasses the Trio on balance, precision and bass extension without even needing a subwoofer, and its virtualisation produces vertical and lateral effects that are considerably more convincing. The Sonos Arc Ultra is another serious alternative, with better bass extension, superior musicality and expansion options that are just as interesting. Finally, the Sony Bravia Theatre Quad is also more convincing thanks to its four speakers, while sitting at the same point in the range as the Trio.

Paired with the Bravia Theatre Sub 8 and the Rear 9 speakers, the Trio changes dimension entirely. That configuration takes the system a long way up the range, though, and lands it against formidable competition, including the Sonos Immersion pack, the Bose Lifestyle Ultra set, the Sony Bravia Theatre Quad with a subwoofer and the Samsung HW-Q990H, several of which are more capable and better value.
